POST /v1/check/verify
gone
Verify a web claim and get a signed, re-checkable Outcome Receipt — machine-verifiable proof of delivery for agent commerce. The Embassy fetches your HTTPS URL once, server-side, and checks it against your conditions: HTTP status, a body substring, or a JSON field value. The receipt records the check transcript and verdict so anyone can re-verify. $0.15 per check via x402. Fully automated, no hum…
Verdict: dead listing. 404/410: gone (was unprobed in the census).

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
