Verify and monitor a third-party x402 endpoint without paying it.

Verify and monitor a third-party x402 endpoint without paying it. Probe the live 402 challenge and check conformance: price, payTo, network, scheme, schema and example quality, whether its own advertised input still reaches a challenge, and whether its description fits the facilitator limit that silently blocks settlement. Then get availability history and a field-level diff since the last observation. Optional recomputation against Base.
