# x402 List - Full Context for LLMs > x402 List is the **agent-first** canonical open directory of x402 protocol services. It indexes APIs that accept payments via the HTTP 402 Payment Required standard and exposes every service, uptime metric, and price as machine-readable JSON. The site is designed primarily for consumption by AI agents and automated systems, while remaining fully browsable by humans. Last updated: 2026-10-08 (live, generated from the directory database). License: the directory data is CC BY 4.0. Attribution required: cite x402-list.com. ## Live directory snapshot - Total listed services: 952 - Verified services (FORTE tier: x402 List paid a real x402 call and the service delivered; no time decay, revoked only on payTo/schema drift; starts at 0 and grows only with paid probes): 12 - Payment-ready services (BASE tier: the endpoint answers a valid x402 challenge and is live, established free by the monitor at scale; discovery, not endorsement; decays to "listed" after 7 days of failing probes): 890 - Categories (8): Data (364), AI (188), Verification (117), Finance (102), Blockchain (71), Other (50), Content (44), Compute (16). All names are valid API category filter values. Curated browse pages exist at /services/category/ (lowercase) only for: Data, AI, Verification, Finance, Blockchain, Content, Compute (whitelisted pages also 404 under 2 live services; non-whitelisted categories have no browse page). - Network codes: AMOY = Polygon Amoy (testnet), ARB = Arbitrum One, ARCT = Arc Network Testnet (testnet), AVX = Avalanche, BSE = Base, BSP = Base Sepolia (testnet), POL = Polygon, SOL = Solana, SOLD = Solana Devnet (testnet), XLYT = X Layer Testnet (testnet). - Operator hub pages aggregate every listed service of one operator, with all endpoints expanded, at /services/operator/. Curated for: LoneStarOracle (/services/operator/lonestaroracle), x402 Atlas (/services/operator/x402atlas), Hugen (/services/operator/hugen), ForgeMesh (/services/operator/forgemesh), Leeworks (/services/operator/leeworks), PayAPI Market (/services/operator/payapi-market), Agentic JP (/services/operator/agentic-jp) (each also 404s while the operator has fewer than 2 live services). - Uptime figures below are built from UTC daily rollups, not rolling hours: the first is the latest daily rollup (one UTC day, usually the current day so far), and 7d / 30d cover the trailing 7 / 30 daily buckets; a 90d window per service is available via the API, built from the same daily rollups and filling progressively since monitoring began. - Each catalogue entry carries a Source line: `submitted` (an operator or user submitted it) or `imported:` (auto-imported from a public x402 index, e.g. `imported:bazaar`); an imported listing is a discovery, not an operator endorsement. ## Facilitators measured on-chain x402-list measures on-chain USDC settlement volume for every facilitator it tracks (36 in total), read directly from each facilitator's own settler addresses on-chain and never self-reported, over a trailing 30-day window. The largest by that measured volume are Coinbase ($571,228), FluxA ($184,041), Polygon Facilitator ($141,269) and Meridian ($136,107). Every figure is a measured floor: USDC only, a conservative undercount, and a record of settlement volume observed on the wire, never an endorsement or a quality ranking of a facilitator. x402-list publishes the full per-facilitator volume, per-chain breakdown, and settler addresses at https://x402-list.com/api/v1/facilitators. ## Change events: payTo rotations, price moves, and schema drift x402-list records every change it observes on the live x402 wire, diffed from the full accepts[] array on each probe of a listed service. Over the trailing 90 days x402-list logged 1,119 payTo (settlement address) rotations and 1,403 price moves. Payment-schema changes are listed in the feed but not counted here. Because the diff compares the whole payment envelope and not the price alone, a payTo rotation at an unchanged price is caught here, a change invisible to anyone tracking prices only, so an agent can check whether the address it is about to pay still belongs to the service it means to pay. x402-list serves the full feed, filterable by service, type, and time window, at https://x402-list.com/changes (human-browsable) and https://x402-list.com/api/v1/changes (JSON). ## What is x402? x402 is an open protocol for machine-native API payments. When a client sends a request to an x402-protected endpoint without payment, the server responds with HTTP 402. In x402 v2, decode the base64-encoded JSON in the PAYMENT-REQUIRED response header; in v1, read the JSON response body. Its accepts[] array lists the accepted payment options (blockchain networks, asset addresses, prices, payTo address). The client picks an option, signs a payment authorization for the exact amount, and retries the request with the signed payload in PAYMENT-SIGNATURE for v2 or X-PAYMENT for v1; the server verifies and settles the payment on-chain and returns the resource with settlement details in PAYMENT-RESPONSE for v2 or X-PAYMENT-RESPONSE for v1. No API keys, no signup, no subscriptions. Any agent with a funded wallet can discover, evaluate, and pay for any x402 service without human intervention. ## Learn guides - [What is x402?](https://x402-list.com/learn/what-is-x402): x402 lets clients pay per API request in stablecoins through HTTP 402, without accounts or API keys. - [x402 vs API keys](https://x402-list.com/learn/x402-vs-api-keys): API keys control access; x402 combines payment and access in one HTTP exchange. - [How do AI agents pay with x402?](https://x402-list.com/learn/ai-agents-x402): An x402 agent reads HTTP 402 payment terms, checks its budget, signs a payment, and retries the request. ## REST API Base URL: `https://x402-list.com/api/v1/` All endpoints return JSON. No authentication required for reads. Rate limit: 200 req/min per IP (soft-throttled above 100: advisory `X-RateLimit-Throttled` header, requests still succeed). Reads are free for agents and point queries; sustained bulk pulling beyond 2,000 requests/day per IP is metered via x402 at $0.01/request on Base (metered responses carry an `X-Meter-Remaining` header). Every response carries an `ETag` and honors `If-None-Match`; endpoints backed by monitoring or on-chain data (services, checks, uptime, status, stats, facilitators) also send `Last-Modified` (derived from the newest record returned, so absent on empty result sets) and honor `If-Modified-Since`. Reference endpoints (categories, networks, openapi.json) are ETag-only. - `GET /api/v1/services` - List services with filters, sorting, pagination, full-text search (each item carries a compact `assessment` summary and a `source` provenance field; filter by provenance with `?source=submitted|imported|imported:bazaar|imported:x402scan`, and by signability of the last observed 402 envelope with `?signable=true|false`: true = no EVM route was observed missing the EIP-712 domain parameters a standard x402 client needs in order to sign, false = at least one such route was observed. A service whose latest assessment has not measured that check yet matches neither value, so omit the parameter to include it; both values filter server-side, so `meta.total` counts the filtered set) - `GET /api/v1/services/{slug}` - Service detail with endpoints, pricing, and the full evidence-backed `assessment` object - `GET /api/v1/services/{slug}/uptime` - Daily uptime snapshots for one service, newest first (`period`: 24h, 7d, 30d, 90d; default 30d; `24h` returns the current UTC day's bucket, not a rolling 24 hours) - `GET /api/v1/services/{slug}/checks` - Raw monitoring check log for one service, newest first (`limit` default 20, max 100; `offset`) - `GET /api/v1/services/{slug}/price` - Captured 402 price movement over time (USD), oldest first - `GET /api/v1/services/{slug}/scores` - Measured assessment sub-scores over time (compliance grade + reliability windows; the sub-scores only, NOT the ranked composite score published on each service page, which is computed live over the current pool by the ranking engine behind `/api/v1/best`; read `compliance_passed` against the `compliance_total` of the SAME point, since the checklist grew from 11 to 14 checks when the signability checks landed: the series carries a step at that date, and earlier points keep the denominator they were measured with rather than being recomputed) - `GET /api/v1/services/{slug}/volume` - Measured on-chain settlement volume over time (USD/day, oldest first; USDC, settler-attributed, a conservative undercount; days with no observed settlement are omitted, so the series is sparse, not a dense daily grid) - `GET /api/v1/services/{slug}/buyers` - Measured distinct on-chain buyers over time (per UTC day, oldest first; same undercount caveat and same sparse-series shape) - `GET /api/v1/facilitators` - On-chain verified facilitator settlement volume - `GET /api/v1/facilitators/{id}` - Single facilitator detail: per-chain volume + `first_activity_at`, on-chain settlers, per-chain distinct buyers (an upper bound), average USD per settlement + a 7d-vs-previous-7d trend, the daily series (`period=all` for full history, matching the services), and the listed-services bridge (which directory services settle on-chain via this facilitator) - `GET /api/v1/stats` - Aggregate statistics - `GET /api/v1/checks` - Global live feed of the most recent monitoring checks across all services, newest first (`limit` default 50, max 100; `offset`) - `GET /api/v1/status` - Aggregate status counts (online/degraded/offline/unknown) plus per-service status, last check, and latest daily uptime rollup, and a count of services offline for 30+ days - `GET /api/v1/changes` - Feed of changes observed on the live 402 wire, newest first: payTo (settlement address) rotations, price moves, and schema changes, diffed from the full accepts[] on every probe (so a payTo rotation at an unchanged price is caught); filter by `?service=&type=payto_changed|price_changed|schema_changed&days=<1-365>` - `GET /api/v1/best` - Best-service recommender: ranks the directory for a stated need in one request, the same two-stage relevance-then-quality scoring as the MCP x402_find_best_service tool (`?q=&category=&network=&max_price_usd=&require_verified=&prefer=balanced|cheapest|fastest|most_reliable&limit=1-20&include_facilitator_context=`); free and metered like the other reads - `GET /api/v1/categories` - Distinct categories currently in use by listed services - `GET /api/v1/networks` - Supported networks with service counts - `GET /api/v1/openapi.json` - OpenAPI 3.1 specification - `POST /api/v1/submit` - Submit a new service, or a facilitator with `"type": "facilitator"` - `POST /api/v1/services/{slug}/request-update` - Owners: propose changes to a listing's declarative metadata (returns a one-time domain-proof token) - `POST /api/v1/services/{slug}/verify-ownership` - Owners: confirm the domain proof; the request then goes to manual review - `POST /api/v1/services/{slug}/reissue-token` - Owners: lost the one-time token, get a replacement emailed to the address on the request (the reply is the same whether or not the request exists, and never carries the token) - `POST /api/v1/suggestions` - Paid suggestion box: submit directory feedback with a $0.10 x402 payment on Base (agent-first) - `POST /api/v1/assess` - On-demand paid assessment: a fresh flagship-LLM comparison of a shortlist of already-assessed services for a stated need, for a $0.25 x402 payment on Base (agent-first, JSON only). Body `{ question, services[] }` (1 to 8 slugs), plus an optional `probe { slug, endpoint_path? }` target that also pays one listed service live and analyzes the response (the price is then $0.25 plus that endpoint price X, non-refundable; the report gains a `data.probe_report` block with a verdict and truncated extracts, never the verbatim third-party body; ignored when live probing is not armed). It charges only for the fresh reasoning, never to read an already-computed assessment; a run that cannot be produced answers 503 before settling, so you are never charged, and there is no refund. The response is a modular report envelope (`data.answer` plus `meta.report_version` / `meta.modules_run`) ## Data model Each service has: name, slug, base URL, description, category; status (online/degraded/offline/unknown) determined by monitoring with hysteresis; two positive tiers (treno D3): a payment-ready flag (BASE: the endpoint answers a valid x402 402-handshake probe and is still responding, derived at read time and decaying to "listed" after 7 days of failing probes, healing on the next good one) and a verified flag (FORTE: x402 List paid a real x402 call and the service delivered; no time decay, revoked only when the payTo address or payment schema drifts on the wire; starts empty and grows only with paid probes); multiple endpoints (HTTP method, path, MIME type); per-endpoint pricing (crypto + USD, network as CAIP-2 id, asset address); daily uptime snapshots; and a last-checked timestamp. Raw checks older than 30 days are purged, but daily uptime rollups are kept, so the API serves uptime windows up to 90 days that fill progressively since monitoring began. Each service also carries a `source` field (provenance): how the listing entered the directory. `submitted` means an operator or user submitted it through /submit; `imported:` means it was auto-imported from a public x402 index (currently `imported:bazaar` from the x402 Bazaar and `imported:x402scan` from x402scan). An imported listing is a discovery, NOT an operator endorsement; it earns the `payment_ready` flag the same probe-based way as any other listing, and can rise to the paid `verified` tier the same way too. The operator can claim and correct an imported listing through the owner-update flow at https://x402-list.com/services/{slug}/update. The `GET /api/v1/services` list can be filtered by provenance with `?source=submitted|imported|imported:bazaar|imported:x402scan`. Each service also carries an evidence-backed `assessment` (null until first assessed): measured families (reliability, x402 compliance grade, site/docs reachability, domain/identity, economics, and on-chain settlement traction) computed only from observed data, a deterministic risk level (blocklist or impersonation match only; never inferred from an LLM, low uptime, or a high price), and an AI synthesis (capability tags, one-line summary, category) whose every field is marked `{value, confidence, source:"ai"}`. On top of that assessment, every service page publishes a ranked VERDICT derived from the measured families: a composite score out of 100, a verbal band (strong, solid, mixed, weak), the service's position inside its category ("#N of M in by measured score"), and the ranked alternatives in that category with their band, 30d uptime and 30d on-chain volume. It is computed deterministically by the same ranking engine that answers `GET /api/v1/best` (ranking generation 3), reads only measured signals (never the AI synthesis), and is not for sale (the paid verify tier is reported beside it and is not one of its inputs). It is scored INSIDE the category: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, a wider set than the measured services the position is counted against, so the identical engine asked for a different pool (`GET /api/v1/best` with no `category` filter, or with another filter) returns a different score for the same service under the same ranking generation, and the two figures are answers to two different questions rather than a contradiction. It degrades to an explicit "not yet ranked", never to a score built from defaults, both on a service with too little measurement and on a category holding fewer than 4 measured services (on a field that thin a pool-relative score measures how empty the category is, not how good the service is). A computed value never overrides a measured one (verified, uptime, pricing, status stay read-only), and `unknown`/null are first-class, never zero-filled. ## Measurement methodology Full write-up: https://x402-list.com/methodology - Two-tier verification (treno D3): a listing carries at most one of two positive badges. "payment-ready" (BASE) is set when an automatic x402 402-handshake probe confirms the endpoint returns HTTP 402 with a well-formed accepts[] payload and it is still responding: a protocol-conformance signal the monitor establishes for free at scale, discovery not endorsement. It decays back to "listed" after 7 days of consecutively failing probes and re-earns automatically on the next successful probe (the underlying historical fact is never erased; an api-key service the monitor cannot probe is exempt). "verified" (FORTE) is earned only by a paid delivery probe: x402 List pays a real x402 call to the endpoint, and if that call settles on-chain and the service delivers, the service becomes verified. The fee covers the cost of the probe (the real outbound payment plus a small handling fee), never the badge itself; a call that does not deliver still costs the fee and earns nothing, and there is no refund. The verified tier has no time-based decay: it is revoked only when the payTo address or payment schema drifts on the wire, and re-earned only by paying again. "listed" means in the directory but carrying neither badge; a slug with no directory row shows the "not listed" badge state. Neither badge can be self-declared, and the verified badge cannot be bought, only earned by a delivered paid call. The purchase is agent and API only (humans do not sign x402 in the browser), documented at https://x402-list.com/api. - Facilitator on-chain state: a facilitator (or one of its chains) counts as on-chain verified only when measured USDC settlement volume greater than zero is read directly on-chain. A declared-but-unmeasured settler stays "listed". The facilitator submission probe is on-chain presence only (never an HTTP 402 probe), advisory, and never auto-approves. - Independent measurement: facilitator volume is measured directly on-chain (EVM chains such as Base via HyperSync, Solana via the Helius transaction API), never taken from x402scan. x402scan and swader are used only to discover new settler addresses, never as the source of the number. - Single-leg anti-double-count: volume is attributed by settler address (tx.from in the settler set, never by function signature) and counts only the settler-sent leg(s) per transaction: one leg for a direct or escrow settle, and all N settler-originated legs for a batch settle, else the single largest leg. So an escrow settle emitting both an incoming and outgoing USDC transfer is never counted twice. All amount math is BigInt. - Per-facilitator memo filtering (Solana-only): on Solana, for a small set of facilitators whose settler wallets also carry non-x402 traffic (coinbase, payAI, bitrefill), an on-chain x402 memo marker is additionally required. On EVM chains such as Base, settlement is attributed by dedicated settler address alone and no memo filter applies. Every other facilitator is treated as clean and gets no filter, so genuine unmemo'd settles are never dropped. The filter can only remove volume, never add it. - Facilitator detail (`GET /api/v1/facilitators/{id}`): a single facilitator node with the same measured volume and settlement figures as the list row, plus the per-(network, token) `chains` breakdown (now carrying `first_activity_at`), the on-chain `settlers` (EOAs), per-chain distinct `buyers`, an average USD per settlement (`avg_settlement_usd_all` / `avg_settlement_usd_30d`, volume over settlement count, null rather than a fabricated 0 when there is nothing to average), a `trend_7d_vs_prev_7d` (the last 7 days over the previous 7, null when the earlier window is empty), a daily `series` (pass `period=all` for the full history, matching the services' `period=all`, and `series_by=chain` for a per-network split), and the `listed_services` bridge: the directory services that settle on-chain via this facilitator (`active_count_30d`, an `all_time_count` that is null until the hourly precompute records it, and a `top` list by 30d volume with slug, name, status). The `buyers` block is per chain and its `total_upper_bound_30d` is a declared UPPER BOUND, not an exact head count: distinct buyers are counted per chain and NOT de-duplicated across chains or tokens, so prefer the per-chain figures. In `listed_services`, service volume is the same 30d floor over the payout mapping and a service on a shared payout is counted at the address level here (the pro-quota split is per-service, not per-facilitator). Every figure is measured on-chain, never self-reported; the node carries `method` and `caveat` strings that restate that in-band. - Uptime: the published per-network method is the per-service mean of the latest daily uptime rollup; per service it is successful checks over total checks from daily snapshots, null (not zero) when a window has no checks. Windows are built from UTC daily buckets, not rolling hours: the `24h` window (`uptime_24h`) is the latest daily rollup, and 7d / 30d / 90d cover the trailing 7 / 30 / 90 daily buckets. - Data windows: daily uptime rollups and facilitator volume snapshots are kept perpetually; only raw checks are purged, at 30 days. The 90d uptime window is built from the daily rollups and fills progressively since monitoring began. - Per-service assessment: the `assessment` field is computed from measured signals only (reliability, x402 compliance, site/docs reachability, domain age, economics) plus a deterministic risk flag and an AI synthesis. Every AI-derived field is labelled `{value, confidence, source:"ai"}` and never overrides a measured value; the risk banner fires only on an exact blocklist or impersonation match, never on low uptime, a high price, or a model guess. The ranked verdict rendered on each service page (score out of 100, band, in-category position, ranked alternatives) is derived from these same measured signals by the ranking engine behind `/api/v1/best`, never from the AI synthesis, from a review, or from a payment. The measured sub-scores and captured prices are also served as time-series at `/api/v1/services/{slug}/scores` and `/api/v1/services/{slug}/price`. - x402 compliance checklist: the compliance grade is a deterministic 14-check list run against the service's own HTTP 402 response, three checks of which cover signability: whether the captured payload declares the current x402 version (2), whether every EVM entry carries the EIP-712 domain parameters (`extra.name` and `extra.version`) that a standard x402 client requires in order to sign a payment, and whether an envelope declaring version 2 was delivered in the `payment-required` header. What we measure is the payment envelope on the wire, not the quality of what the service sells. A service with at least one EVM route missing those domain parameters does not grade above C, and the claim behind that ceiling is precisely "a standard x402 client cannot sign a payment for this route", never "this service is unreliable". A check that could not be evaluated (nothing captured yet, or not applicable, for instance the EIP-712 domain on a Solana-only service) reads unknown and is left out of the denominator, never counted as a failure. The list grew from 11 to 14 checks when the signability checks landed, so the `/api/v1/services/{slug}/scores` history carries a step at that date and each point must be read against its own `compliance_total`. - Per-service on-chain traction: the `assessment.traction` block is a measured, deterministic snapshot of a service's own settlement activity (30d volume, tx count, distinct buyers, largest-buyer concentration, a 7d-vs-30d trend). It is attributed the same way as facilitator volume, by settler address over the service's payTo mapping, and is scoped to USDC settlements only; it is a conservative UNDERCOUNT, counting only what the settler-attribution monitor observed, so real volume can exceed what the block shows. null != 0: `status: "measured"` reports real numbers where 0 is an honest "never settled on-chain via a facilitator"; `status: "no-payto"` (no known payTo) and `status: "unmeasured-network"` (payTo only on a network we do not measure) null every metric rather than fake a zero; `status: "unresponsive"` suppresses a shared-payout member whose probe has been failing for 7 days (its share of the shared address is not attributed to it while it is down). When a payTo is shared across services (`shared_payout: true`, e.g. a shared fee router) the operator-level VOLUME is attributed PRO-QUOTA: `volume_usd_30d` is the address total over the number of services currently sharing the payout (a declared convention, not an individually observed measure), while `tx_count_30d` and `unique_buyers_30d` stay whole operator-level figures, never divided and never fractional. The ratios `top_buyer_share_30d` and `trend_7d_vs_30d` are left whole (invariant under the division). Because the volume is pro-quota it sums correctly across services; the counts do not: they are whole operator-level figures, so never sum `tx_count_30d` or `unique_buyers_30d` across services that share a payout. The daily series stay address-level too, so do not sum `volume_usd_30d` or buyers across shared-payout services from the series. Traction is one small input to service ranking, deliberately never dominant, and it gates on recency: no settlement in the rolling 30 days before the figure was computed (a window ending at computation time, not aligned to UTC days) contributes 0 to the term. The daily series behind it are served at `/api/v1/services/{slug}/volume` and `/api/v1/services/{slug}/buyers`. Both the `traction` block and those two series carry a fixed `caveat` string that restates the conservative undercount in-band (the block also states the pro-quota convention on a shared payout; the series states it is operator-level, not pro-rata). The block also carries `first_settlement_at` (the first on-chain settlement observed for the service, null when never recorded), all-time totals `volume_usd_all_time` and `tx_count_all_time` (summed over the service's payout mapping since listing; on a shared payout `volume_usd_all_time` is attributed PRO-QUOTA exactly like the 30d volume, while `tx_count_all_time` stays a whole operator-level count), the per-settlement `median_settlement_usd_30d` and `max_settlement_usd_30d` (invariant amounts, NEVER divided pro-quota), `settled_via` (the facilitator ids that settled this service over 30d, ordered by volume), and `shared_with_services` (the other listed services currently sharing this payout address, as {slug, name}, empty when the payout is not shared). `settled_via`, `shared_with_services`, `first_settlement_at`, `median_settlement_usd_30d` and `max_settlement_usd_30d` are invariant facts and are never divided; a snapshot stored before this extension leaves the new fields null or empty (never a fabricated 0). - Directory-wide traction (the citable aggregate): the home page and `GET /api/v1/stats` also carry a directory-wide `traction` block (`unique_buyers_30d`, `volume_usd_30d`, `settlement_count_30d`, plus `measured_services` and `measured_networks`) over a window that starts at 00:00 UTC 30 days back, so 30 full UTC days plus today so far. It is computed DIRECTLY over the raw settlements (the table is unique on `(network, tx_hash, log_index)`, so a straight aggregate IS the dedup on settlement identity) and is NEVER summed from the per-service figures: distinct buyers are not additive across services, and summing the pro-quota volume would reintroduce the shared-attribution rounding. It is USDC only and the same conservative undercount: a measured floor across the listed services, NOT an ecosystem total. `settlement_count_30d` is the deduped settlement count, deliberately distinct from any per-service `tx_count_30d` (a dedup count, not a sum); `measured_networks` are network abbreviations there, while the per-service block uses CAIP-2 ids. The block also carries a coverage KPI and a concentration disclosure: `coverage_of_measured_flow_pct` is that listed dedup 30d volume as a percentage of the flow measurable by our tracked settlers over the same window (the facilitator daily volume we measure, NOT the whole ecosystem, so it is a floor on our coverage of the flow we can see), and `top_10_services_share_pct` is the share of that 30d dedup volume held by the top 10 services (ranked by volume via the payTo mapping; the numerator is the deduped settlements mapped to any top-10 service, never a sum of the per-service figures, and the denominator is the same whole-window dedup total). One level deeper, `top_1_service_share_pct` is the single largest service's share of that same 30d dedup volume (so `top_1_service_share_pct` <= `top_10_services_share_pct` by construction), and `top_1_service_top_buyer_share_pct` is that one service's own largest-buyer share of its volume. All are precomputed hourly and are `null` until the first refresh (never a fake 0). Beside the coverage KPI the block also carries `measured_flow_freshness`, which says whether the flow that KPI is measured over is still being ingested at all: `oldest_cursor_age_seconds` (the age, at response time, of the most-behind settler-sync cursor), `stale_sync_groups` out of `total_sync_groups` (a sync group is one facilitator, network and token; frozen means no clean sync completion in 2 hours, against a 15-minute cadence) and `stale_facilitators` out of `total_facilitators` (a facilitator counts as stale as soon as ONE of its groups is frozen, never averaged away by its freshest network). Unlike the figures above it is read live on each request rather than precomputed, and it is always present: an empty sync state reads 0 of 0 with a null age, never a fabricated freshness. Without it a coverage percentage computed over a frozen ingest would be byte-identical to one computed over a live ingest. The block carries its own `method` and `caveat` strings that restate the dedup, the do-not-sum rule, the coverage denominator, and the measured-floor frame in-band. Alongside the traction block, `GET /api/v1/stats` also carries four directory-health figures: `verified_count` (services in the FORTE verified tier: a paid delivery probe settled and delivered, no time decay, the same predicate as the `?verified=true` filter; starts at 0 and grows only with real payments), `payment_ready_count` (services in the BASE payment-ready tier: they answer a valid x402 challenge and are alive within the 7-day decay window, the same predicate as the `?payment_ready=true` filter, the broad signal `verified_count` used to carry), `listing_growth` (`new_7d` / `new_30d`, services first listed in the last 7 / 30 days), and `facilitator_volume_usd_30d` with a `facilitator_volume_note` (aggregate 30d settlement volume across measured facilitators, a non-deduped SUPERSET of the listed-services flow, null until snapshots exist). ## Service catalogue 952 services listed.

Around it sit ~19 deliberately misbehaving payment scenarios that never settle and never contact a facilitator - a 402 that ignores every valid payment, one that asks for 1,000,000 USDC, one naming a nonexistent chain, one returning a corrupt receipt, and ten malformed 402 envelopes - so you can test what your client does when a paywall is broken or hostile.

Three POST endpoints, all deterministic and LLM-free: identical input always returns byte-identical output, so results are cacheable and replayable. POST /api ($0.01) - dataset quality verdict. Send a JSON array of rows; get a 0-100 score, a RELIABLE / USABLE_WITH_CLEANING / UNRELIABLE judgement, and exact per-check facts: completeness, nulls, type consistency, impossible values, exact and near duplicates, statistical outliers, cardinality. On financial data it also reports cross-source price divergence for the same asset. POST /api/clean ($0.04) - deterministic data cleaning. The response body IS the clean data: post a JSON array of row objects and the same array comes back repaired; post one object and one object comes back; post plain text and text comes back. CSV is accepted and returns parsed rows. Fixes broken encoding and mojibake ("Café" becomes "Café"), strips leftover HTML tags and entities, removes zero-width and invisible characters and non-breaking spaces, normalises whitespace. Repairs how data was encoded, never what it says: a negative price is reported, not rewritten. Flags failed extractions such as captcha walls and error pages instead of passing them off as content. POST /api/clean/audit ($0.12) - the same repaired data plus a reversible ledger of every transformation. Replaying it backwards reconstructs the exact input, byte for byte. Use it to clean scraped data, fix encoding, remove HTML from text, deduplicate rows, validate dataset contents, assess data quality, and decide whether to trust data before ingesting, indexing or trading on it. Never destroys a legitimate value: "None" stays a surname, "NA" stays Namibia, a Persian ZWNJ and an emoji joiner survive untouched. The full ruleset is published at GET /api/clean, readable before paying. Also a free Python library: pip install scrubkit. - Status: online · payment-ready (answers a valid x402 challenge, live) - Uptime: latest daily rollup 100.00% / 7d 100% / 30d 99.3% - Base URL: https://www.aidatatools.dev/api - Networks: BSE, SOL - Pricing: from $0.01 to $0.12 · 3 prices · 3 endpoints - Source: submitted - Detail: https://x402-list.com/services/data-quality-gate ### cogDepot - Category: AI - Description: Anonymous B2B broker for AI-agent service exchanges.

A first-time submission from your own domain is free. One submission per email every 7 days. Declare endpoint methods with `"POST /v1/generate"` or `"GET /v1/models"` in endpoints (an array or newline-separated string). Bare paths keep the GET-first probe order, with POST as a fallback on an invalid response. If any endpoint is POST, you may supply `example_request_body` as a JSON value, for example `{"wallet_address":"0x0000000000000000000000000000000000000001"}`. The same body is used for all declared POST endpoints and saved for monitoring after approval. Maximum 4096 UTF-8 bytes when serialized; no secrets or API keys. Without a declared body, POST probes send `{}` with `Content-Type: application/json`. A POST that returns HTTP 400 or 422 produces a probe error asking for an example body with the required fields; the submission is still queued for manual review. If the LATEST submission for the same email OR the same service URL was rejected less than 14 days ago, resubmitting is not free: it costs a one-time $0.50 USDC (x402) payment on Base, and that payment replaces the 7-day cooldown (pay and re-enter immediately; a still-pending or approved latest is unaffected and stays on the ordinary cooldown). Once 14 days have passed since the rejection, resubmitting is free again. The paid flow is the standard x402 handshake on the submit endpoint itself: the first call returns HTTP 402 with a PAYMENT-REQUIRED header and an accepts[] body (single option, $0.50 USDC on Base), and an error code `resubmission_fee_required`; sign the payment and retry the same request with a PAYMENT-SIGNATURE header. On success the 201 carries a PAYMENT-RESPONSE header. This paid path is agent-only (the browser form cannot sign a payment). If the service URL is hosted on a free compute platform (vercel.app, workers.dev, pages.dev, netlify.app, onrender.com, railway.app, fly.dev, herokuapp.com, replit.app, glitch.me, deno.dev, pythonanywhere.com, firebaseapp.com, web.app and similar), on a free subdomain or dynamic-DNS service (eu.org, is-a.dev, duckdns.org and similar), on wildcard DNS that maps a name onto an IP (nip.io, sslip.io and similar) or on a hosted sandbox (hf.space, koyeb.app, codesandbox.io and similar), submitting it costs a one-off $1.00 USDC (x402) payment on Base, with error code `free_host_fee_required`. Waiting does not make it free and it is never refunded: it buys a place in the human review queue, not a listing, not priority, and no review deadline. The two fees are orthogonal and stack: a resubmission from a free compute host inside the 14-day window is a single $1.50 payment. This door is agent-only too. When the charge layer is offline the submission is rejected with HTTP 400 instead of being offered the paid path. A service URL on static-only hosting (github.io, gitlab.io, surge.sh, neocities.org, r2.dev and similar) is rejected with HTTP 400 at any price, because a static host cannot serve the dynamic 402 an x402 service has to serve. A service URL on an ephemeral dev tunnel (ngrok, trycloudflare.com, localhost.run, serveo.net and similar) is rejected with HTTP 400 too: the URL stops resolving when the tunnel closes, so paying would buy nothing listable. The website_url field is never charged and is rejected only when it is a dev tunnel. Facilitator submissions have no paid door at all: a website_url on any free-hosting or dev-tunnel domain is rejected with HTTP 400. ## Updating a listing you operate (owner updates) Service owners can update their own listing without email back-and-forth, via a per-request domain proof: 1. `POST /api/v1/services/{slug}/request-update` with your email and only the fields you want to change (name, description, website_url, category, contact_email, base_url, endpoints_add, endpoints_remove, endpoints_method). An empty or omitted field means unchanged; no field can be cleared through this channel, but listed endpoints can be removed or change method, with review. Each `endpoints_add` entry is a path, optionally prefixed with its HTTP method: `/v1/summarize` or `POST /v1/chat/completions`. GET and POST are the accepted methods and an entry with no prefix is taken as GET. Method and path together identify an endpoint, so `POST /x` is a new addition even when `GET /x` is already listed, and it is probed for HTTP 402 with the method it declares. Each `endpoints_remove` entry names a currently listed endpoint in the same form (`GET /v1/old`, max 50); the listing must keep at least one endpoint, and a removed endpoint stops being monitored while its price history is kept. Each `endpoints_method` entry is `GET /v1/resource -> POST` (current method and path, then the new method); the endpoint is probed with the new method after verification, and the change is applied only if it answers with a valid x402 HTTP 402 there. The same endpoint cannot be both removed and changed method in one request. 2. The 201 response returns a one-time `ownership_token` (shown once, only its hash is stored; it is the FIRST field of the body, so a truncated log cannot cut it off). Publish it as its own line at `{base_url origin}/.well-known/x402list.txt` on the CURRENTLY listed domain. 3. `POST /api/v1/services/{slug}/verify-ownership` with the `request_id`. The server re-fetches the well-known file, consumes the token (72h expiry), and the request goes to manual human review; the outcome arrives by email. If the token is lost, `POST /api/v1/services/{slug}/reissue-token` with `{request_id, email}`, using the same email that created the request. The replacement is sent BY EMAIL to the address already on the request and never appears in the HTTP response, which is identical whether or not a matching request exists: whether a pending update request exists is not public. One re-issue per request. Lost twice: send a new update request once the current one lapses, since a pending request with a live token is what holds the 7-day cooldown on that email and listing. A request whose token has already expired holds nothing, so its replacement can go out immediately. Measured data (verified status, uptime, pricing, payTo) can never be changed this way: it is monitor- and chain-derived, read-only for everyone. A browser form for the same flow is at `https://x402-list.com/services/{slug}/update`. To request delisting, email info@x402-list.com or update your listing at /services//update. ## Suggesting a change to the directory (paid feedback) The feedback channel for the x402 List directory is itself paid in x402: `POST /api/v1/suggestions` accepts a suggestion (text, optional category among feature/bug/data/other, optional contact email) for a one-time $0.10 USDC (x402) payment on Base. The fee is anti-spam skin-in-the-game, so there is no refund. The paid flow is the standard x402 handshake: the first call returns HTTP 402 with a PAYMENT-REQUIRED header and an accepts[] body (single option, $0.10 USDC on Base) and the error code `suggestion_fee_required`; sign the payment and retry the same request with a PAYMENT-SIGNATURE header. On success the 201 returns `{ id, status: "received" }` with a PAYMENT-RESPONSE header. Suggestions are internal and manually reviewed; they are never published and there is no public roadmap. This endpoint is agent-first (JSON only). ## Machine-readable resources - https://x402-list.com/llms.txt - Short synthetic index for LLMs - https://x402-list.com/methodology - How the payment-ready and verified tiers, uptime, and on-chain facilitator volume are measured - https://x402-list.com/openapi.json - OpenAPI 3.1 specification - https://x402-list.com/sitemap.xml - XML sitemap (includes dynamic service pages) - https://x402-list.com/feed.xml - RSS 2.0 feed for new services - https://x402-list.com/changes - Human-browsable feed of recent service change events (payTo rotations, price moves, schema changes) - https://x402-list.com/changes.xml - RSS 2.0 feed of recent service change events - MCP server (hosted, Streamable HTTP): https://mcp.x402-list.com/mcp - MCP server (local stdio): `npx -y x402-list-mcp` - 7 tools; x402_assess_services is Paid ($0.25 USDC on Base), the other 6 read-only: x402_search_services, x402_get_service, x402_find_best_service, x402_check_health, x402_facilitator_volumes, x402_change_events - Operated by: Cosimo Miccolis (individual, Italy), who is also the data controller.
