Sources are queried per request rather than served from a stored snapshot. Metadata and evidence summary only: this does not scan your systems and is not security advice.

Verified route: POST /api/v1/x402-inspector/x402-v2, taking {url}. At verification it performed a real live probe of the submitted target and reported its observation accurately. Important limitation: it probes with GET only and its input schema has no method parameter, so any endpoint that serves its challenge on POST is reported as having no challenge. POST-only is the common shape for x402 routes, so treat a no_challenge result as inconclusive rather than as evidence that an endpoint is unprotected. The badge covers delivery of a real paid scan, not the correctness of its verdicts. Base only.
