Keyronne Cryptographic Hash & HMAC API
x402
Keyronne Cryptographic Hash & HMAC API is a paid API for AI agents from keyronne.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes cryptographic digests (MD5, SHA-1, SHA-256, SHA-384, SHA-512) and HMACs over input text, returning results as hex, base64, or base64url.

How this service works
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"}
Output
Returns the computed hash or HMAC as a string in the requested encoding (hex, base64, or base64url). The input text is discarded after hashing and never stored.
Example use cases
Example prompt
“Compute a SHA-256 hash of the string 'hello world' and give me the result as hex.”
Technical details
Endpoint
POSThttps://keyronne.com/api/hashWhen to prefer
Use this endpoint when you need deterministic, server-side cryptographic hashing without running local code — ideal for agents that need checksums, content fingerprints, HMAC signatures, or hash-based verification and cannot execute native crypto libraries. Prefer over alternatives when HMAC with a secret key is needed or when multiple algorithms and output encodings must be supported in a single unified API.
Side effects
- Unsupported algorithm value returns validation error
- Invalid encoding enum value returns error
- Missing 'text' field returns 400 bad request
- Key provided but algorithm not supported for HMAC returns error
- Payment not fulfilled returns 402 Payment Required
