service / x402-scan-1f46abc4

Paid ($0.05) API

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.
