Current paid endpoints; minimum quoted prices in USD where available; first capture dates in UTC
MethodPathDescriptionPriceNetworkAsset402 channelCaptured
POST/paid/a2aA2A (Agent2Agent) protocol JSON-RPC endpoint, SendMessage only. Authorizes up to $0.75 (the highest-priced skill); settlement charges the invoked skill's real per-skill price. Base (EVM) only -- for Solana use the REST or MCP endpoints. See /.well-known/agent-card.json for the skill catalog and per-skill pricing.$0.75BaseUSDCheadersince 08-31
GET/paid/aeo-auditURL -> AI-readiness report. Checks schema.org structured data, crawlability (robots.txt, meta robots, canonical), and llms.txt presence, then returns a 0-100 score with specific recommendations for what's missing. Results are cached for 24 hours per URL.$0.031Base+SolUSDCheadersince 08-31
GET/paid/contentFetch a URL with a real rendered browser (JavaScript executed) and return clean Markdown. Results are cached for 24 hours per URL, so repeat calls for the same page are fast and don't re-render.$0.005Base+SolUSDCheadersince 08-31
POST/paid/extractExtract structured data from content you already have (e.g. from a prior /content call), using AI. No browser render involved -- pure AI extraction, cheaper and faster than fetching a URL fresh. Use this when you already have the text; use /extract-url if you only have a URL.$0.016Base+SolUSDCheadersince 08-31
POST/paid/extract-urlFetch a URL with a real rendered browser and extract structured data from it in one call, using AI (tries multiple models in sequence for reliability). Use this when you don't already have the page content; use the cheaper /extract if you do. Results are cached for 24 hours per URL+schema combination.$0.021Base+SolUSDCheadersince 08-31
GET/paid/fetch-cleanAlias of /content for agents that call a single URL directly. Fetches a URL with a real rendered browser (JavaScript executed) and returns clean Markdown. Results are cached for 24 hours per URL.$0.005Base+SolUSDCheadersince 08-31
GET/paid/pdfFetch a URL with a real rendered browser (JavaScript executed) and return a PDF of the full page. Not JSON -- the response body is the file itself. Results are cached for 24 hours per URL. Cache status and fetch time are reported in the X-Cached and X-Fetched-At response headers.$0.01Base+SolUSDCheadersince 08-31
GET/paid/pingHealth and payment-path check. Returns server time and a confirmation that your x402 payment settled. Cheapest endpoint in the catalog; use it to verify your client's payment flow before calling paid tools.$0.001Base+SolUSDCheadersince 08-31
GET/paid/researchquery -> up to 10 deduped, rendered sources as one token-budgeted bundle (~8,000 tokens combined). Combines /search (three-provider failover, region=tw Taiwan lane) with /content's rendered-page fetching internally, so you get one call instead of assembling search-then-fetch yourself. Sources are deduped by domain. Requires at least 3 successfully fetched sources to succeed -- returns sources_requested and sources_returned so you can see how many of the candidate set actually came back.$0.031Base+SolUSDCheadersince 08-31
GET/paid/screenshotFetch a URL with a real rendered browser (JavaScript executed) and return a PNG screenshot of the full page. Not JSON -- the response body is the image itself. Results are cached for 24 hours per URL. Cache status and fetch time are reported in the X-Cached and X-Fetched-At response headers.$0.01Base+SolUSDCheadersince 08-31
GET/paid/searchquery -> structured search results (title, url, snippet), up to 10 per call. Backed by three providers with automatic failover (DataForSEO primary, Tavily and Serper as fallback) so a single provider outage doesn't take the endpoint down. Pass region=tw for a Traditional Chinese / Taiwan-region search lane. Results are cached for 24 hours per query+region.$0.005Base+SolUSDCheadersince 08-31

How the score works

What the score read on this service: status online, 100% uptime 30d, 547ms response p95, x402 compliance 14 of 14, $0.001 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 389 listings, this one among them: the same 389 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Paid probe: delivered (HTTP 200) on 2026-09-02. Settled via coinbase ($0.16, 11 tx). Traction is a conservative undercount; first settlement seen 2026-08-26.

Pay-per-call web data APIs for AI agents over the x402 protocol. Rendered-page fetching, structured extraction, search, research bundling, and an A2A (Agent2Agent) protocol endpoint with a multi-turn research orchestrator. No accounts, no API keys.

TariffMonkee is a listed x402 Data API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at . Latest service check observed at . Service data JSON · Measurement methodology.

Page rendered at . This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: . Latest price capture: . Prices are recorded quotes, not a promise of availability. Token assets and payment terms are listed separately. Endpoint data JSON · Price history JSON · Measurement methodology.

Assessment computed at . Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor. The comparison score is out of 100 within this category. Assessment JSON · Measurement methodology.

Observed daily coverage: 2026-09-16 to 2026-10-15 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp. Latest settlement in the assessment: . Uptime and response JSON · Volume JSON · Buyers JSON · Measurement methodology.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.

Daily snapshot total, 30d: $0.16, peak $0.05 on 09-30. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.

Daily address snapshots: 2026-09-16 to 2026-10-15 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here. † marks a recorded $0.00 with settlements.

Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.
