How this service works
Dated topic news search, x402 service diagnostics, annual SEC financial facts, CSV validation, citation-source comparison, web extraction and email domain checks for agents. Find recent topic news with deduplicated source links and optional source-linked headline highlights; retrieve six annual US-GAAP USD fields by CIK with filing links, same-filing growth checks and optional observed revisions; check supplied CSV and citations; extract public page text, rendering JavaScript in a headless browser when needed; inspect email address syntax and mail-domain DNS. Pay per call with native USDC on Base or Solana via x402, without a separate API key. Wallet-first free trials cover CSV, column-spec, citation and static-page operations.
Output
Returns a JSON report containing: a linter grade (A-F) and numeric score with per-category breakdowns (docs, protocol, directory), a compliance grade and score, a list of findings each with an ID, title, status (pass/fail), severity, category, and suggested fix, plus coverage metadata (paid routes probed, head observations, delivery verified flag), a unique report_id, scan timestamp, and expiry timestamp.
Example use cases
Pre-launch x402 compliance audit
“Before I go live, can you scan https://api.mynewservice.com with paths /v1/charge and /v1/refund for x402 conformance and tell me the compliance grade and any critical findings?”
Debugging failed x402 payment route
“My x402 payment API at https://api.paygateway.io keeps getting rejected by clients — can you run a conformance scan on /v1/invoice and /v1/settle and show me what protocol rules are failing?”
Continuous CI compliance check
“Run a fast-mode conformance scan on https://api.staging.example.com covering /payments and /auth so I can see the linter score and whether delivery is verified before merging this branch.”
Technical details
Endpoint
POSThttps://api.mekler.ai/v1/services/conformance/scan-origin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to audit or certify that an x402-enabled API correctly implements the x402 payment protocol — covering protocol headers, documentation presence, and directory listings. Prefer it over generic HTTP health checks or manual inspection when you need a structured, graded compliance report with actionable findings and fix suggestions, especially before launching a new x402 service or diagnosing client-facing rejection issues.
Side effects
- Invalid or unreachable origin URL returns an error or failing HTTP-reachable finding
- Paths exceeding 50 items or 1024 characters are rejected by schema validation
- Non-public or private IP addresses blocked by public-address checks
- Malformed idempotency key pattern causes request rejection
- Origin returns unexpected content types that prevent protocol evaluation
- Timeout when origin is slow to respond, resulting in partial or inconclusive evaluation
