About this agent

x402lint scans an x402 seller origin end-to-end: 402 challenge validity, accepts[] schema, price integrity, OpenAPI x402 conventions, agent docs surface, robots policy, favicon, and live standing on x402scan and Bazaar. Returns an A-F grade with per-check evidence and one-line fixes. 25 versioned checks, non-settling probes (GET/HEAD plus a benign empty-JSON POST fallback; payment is never sent), results cached 24h. Cached full reports are free; a paid $0.05 scan forces a fresh run. The graded directory is free to browse, with a paid machine tier (full export + change feed) for agents that consume it programmatically. Built by the Hexanon fleet, which runs seven live x402 products.

Directory change feed
Paid ($0.03). Everything that changed in the graded directory since a timestamp: newly listed origins (changeType "new"), grade changes ("grade_changed", with previousGrade/previousScore), and plain re-scans ("rescanned"). Poll this to keep a local copy of the directory fresh without re-buying the full export. An invalid since/limit is an uncharged 400.
x402lintchanges
Full directory export (machine tier)
Paid ($0.10). The entire graded directory in one machine-shaped response: every listed origin with grade, score, grade history, legitimacy signals, branding, verification and featured status — the same record shape as /v1/directory plus gradeHistory, firstSeenAt, and scanCount. Capped at 10,000 records (truncated:true if hit). Grades measure protocol conformance only and are NOT endorsements.
x402lintexport
Priority fresh re-scan
Paid ($0.05). ALWAYS runs a fresh 25-check scan of the origin (non-settling GET/HEAD + benign empty-POST probes), bypassing the 24h cache — use free GET /v1/report to read the cached result. Concurrent requests for the same origin join the in-flight scan rather than double-scanning. Returns grade, score, per-check status + evidence + fix instructions, and a shareable report URL. Unreachable/broken origins are a valid graded result (F). 504 processing responses and errors are never charged.
