Reads the challenge from both the response body and the v2 PAYMENT-REQUIRED header. Free.

Free.

Pass your own dependency list to check it in one call. Derived from a daily external re-audit of the whole MCP package population — an event exists only because a snapshot from before it exists. Free.

From a daily audit of the MCP server catalog. Free.

Formerly: deep trust check, endpoint track record, bulk trust dataset, and the cross-domain Data API. Includes the client-side spend-cap gotcha for x402-fetch.
