  • x402-probeUnpaid probe of a public https URL for x402 payment requirements ($0.005 USDC).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Unpaid probe of a public https URL for x402 payment requirements ($0.005 USDC). Never pays. Returns HTTP status, latency, whether 402/payment-requirements parse, networks, min price, schema flag. https only; caps ~12s, 200KB, 5 redirects. Factual only; as is, no guarantee. Not a rating or certification. Provided as is, with no warranty or guarantee of accuracy or fitness. Nothing is stored.

    • title: x402 probe
    • readOnlyHint: true

    • openWorldHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
