How this service works
Cryptographic hash of a text string - sha256 (default), sha512, sha1 or md5 - returned as hex and base64. Use it for content fingerprints, integrity checks and deterministic ids; pure computation, instant.
Output
Returns the cryptographic hash of the input text in both hexadecimal and base64 encoding, using the specified algorithm (sha256, sha512, sha1, or md5).
Example use cases
Example prompt
“Can you hash the text 'Hello, World!' using SHA-512 and give me both the hex and base64 digests?”
Technical details
Endpoint
POSThttps://agent402.tools/api/hashWhen to prefer
Use this endpoint when you need a quick, paid-per-call cryptographic hash of a text string without setting up local crypto libraries. Ideal for agents needing one-off integrity checks, fingerprinting, or digest generation supporting multiple algorithms via a single API.
Side effects
- Text input exceeds 100KB limit — request rejected
- Invalid algorithm name supplied — returns error
- Missing 'text' field in request body — validation error
- Payment failure via x402 protocol — 402 response with payment details
