POST /api/hash

unprobed

Compute cryptographic digests and HMACs deterministically: MD5, SHA-1, SHA-256, SHA-384, SHA-512, output as hex, base64, or base64url. Add a "key" for HMAC. Built for checksums, content addressing, and signature verification. Inputs are hashed and discarded. POST a JSON body like: {"text":"hello world","algorithm":"sha256","encoding":"hex"}

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://keyronne.com/api/hash' -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.
