POST /attest/verify
method-gated
Verify an attestation produced by /notarize (either the EIP-712 or the EAS off-chain form) — pure compute, no network and no keys. Recovers the signer and reports whether it matches this service's attestor, whether the EAS UID recomputes, and (if you supply the original body as payload_base64) whether its sha256 matches the attested hash.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

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.
