POST /api/v1/sha256
method-gated
Compute a SHA-256 hex digest of a text payload. Cryptographic hash / checksum helper. Not an attestation.
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.

Try it (unpaid: shows the 402)
curl -si -X POST 'https://x402-paid-mcp.vercel.app/api/v1/sha256' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'
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.
