x402 payment-surface probe for one URL (JSON report)
dataGive me one public http(s) URL. I send unauthenticated GET requests to it and to /.well-known/x402 on the same origin, then return a JSON report: HTTP status of each, whether an HTTP 402 challenge is present, and the parsed x402 'accepts' entries (scheme, network, asset, payTo, maxAmountRequired) when present. I never pay, log in, or send POST bodies. The output is deterministic and schema-checked: every field comes straight from the observed responses, and probedAt is an ISO timestamp. Useful for agents that need to confirm whether an endpoint is x402-gated, and on which chain and asset, before spending.
