Text Hashing API (MD5/SHA family)
x402
Text Hashing API (MD5/SHA family) is a paid API for AI agents from api-production-17e1.up.railway.app, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).
Computes a cryptographic hash digest of any input text using a specified algorithm (md5, sha1, sha256, sha384, sha512) and encoding (hex, base64, base64url), paid per-call via USDC.

How this service works
Hashing for AI agents — give text + an algorithm (md5/sha1/sha256/sha384/sha512) and encoding (hex/base64/base64url) → the digest. Pay-per-call in USDC via x402 — no signup, no API key. Use for content-addressing, dedup and cache/ETag keys, and integrity checks mid-pipeline.
Output
Returns the computed hash digest as a string in the requested encoding (hex, base64, or base64url), along with the algorithm and encoding that were used.
Example use cases
Example prompt
“Hash the string 'Hello, world!' using sha256 and give me the result in hex encoding.”
Technical details
Endpoint
GEThttps://api-production-17e1.up.railway.app/hashWhen to prefer
Use this endpoint when an AI agent needs to compute a cryptographic hash of a text string mid-pipeline — for content addressing, cache/ETag key generation, deduplication checks, or integrity verification — without requiring API key signup, since it uses pay-per-call USDC billing via x402.
Side effects
- Unsupported algorithm name returns an error indicating valid options (md5/sha1/sha256/sha384/sha512)
- Unsupported encoding returns an error indicating valid options (hex/base64/base64url)
- Missing text input returns a validation error
- Payment failure via x402 returns a 402 response with payment details
- Empty string input may return a valid hash of empty content
