MethodPathDescriptionPriceNetworkAsset402 channelCaptured
GET/api/config-lintPOST a YAML, JSON, TOML, .env, Dockerfile or GitHub Actions workflow (max 64 KB, kind auto-detected). Returns syntax errors and common mistakes with line numbers and rule IDs: tabs, duplicate keys, unpinned images and actions, root user, curl-pipe-shell, script injection, committed secrets. Optional SARIF.$0.005Arbitrum One+Avalanche+Base+Pol+SolUSDC, USD Coinheadersince 11-11
GET/api/context-packPOST documents or text chunks plus a token budget. Returns deduplicated, query-ranked, whitespace-compressed context that fits the budget, with source offsets and a token estimate. Deterministic, no LLM.$0.01Arbitrum One+Avalanche+Base+Pol+SolUSDC, USD Coinheadersince 11-11
GET/api/dataset-checkPOST CSV text or JSON rows. Returns inferred schema plus null, missing, duplicate, type-mismatch and numeric outlier findings per column, and a 0-100 quality score. Never changes values.$0.01Arbitrum One+Avalanche+Base+Pol+SolUSDC, USD Coinheadersince 11-11
GET/api/extract-contactsFetch one public web page and return emails, phone numbers and social profile links found on it.$0.005Arbitrum One+Avalanche+Base+Pol+SolUSDC, USD Coinheadersince 11-11
GET/api/html-to-ragPOST HTML or a public URL. Strips scripts, styles, nav and footers, converts to Markdown and returns heading-aware chunks with heading paths, token estimates, stable hashes and configurable overlap. For embedding and RAG pipelines. Tables: HTML tables become GitHub-flavored Markdown with a | --- | header row. Nested tables are lifted out as labelled sub-tables under ### Parent row → column headings, with (see Parent → column) in the parent cell. If two nested tables would get the same label, later ones get ', table 2', ', table 3' in document order, so headings stay unique and the same on every run. Pipes in cells are escaped as \|. Links inside cells become [text](url); bold, italic and code markers in the link text are kept; the title attribute is dropped; an href that starts with # is not turned into a link. Example: a Basic row with a nested Limits table becomes | Basic | (see Basic → Limits) | plus a ### Basic → Limits sub-table.$0.005Arbitrum One+Avalanche+Base+Pol+SolUSDC, USD Coinheadersince 11-11

Detects and redacts emails, phone numbers, Luhn-valid card numbers, SSNs, IBANs (mod 97), IPv4/IPv6 addresses, API keys, JWTs, private keys and password assignments.

How the score works

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 123ms response p95, x402 compliance 14 of 14, $0.005 price against the category. 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 492 listings, this one among them: the same 492 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.

All measured facts

What it does

12 pay-per-call web data and AI developer utility APIs for agents: URL to Markdown, contact extraction, HTML to RAG chunks, context packing, dataset checks, JSON repair, schema diff, prompt-injection scan, PII redaction, config lint, ID validation and x402 lint. USDC via x402 on Base, Arbitrum, Polygon, Avalanche, Sei or Solana. No signup, no API key.

Johto Data is a listed x402 Data API. Captured payment terms name Arbitrum One, Avalanche, Base, Polygon, 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.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.
