Cryptographic Hash API (MD5/SHA-1/SHA-256/SHA-384/SHA-512)
x402
Cryptographic Hash API (MD5/SHA-1/SHA-256/SHA-384/SHA-512) is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.0022/call, status unknown (last checked 2026-09-14).
Computes a cryptographic hash of any text input using a chosen algorithm (MD5, SHA-1, SHA-256, SHA-384, or SHA-512) and returns the hex digest.

How this service works
hash sha256 generator, SHA256 hash generator, SHA-256 hash, generate SHA256 hash, SHA-1 SHA-256 SHA-384 SHA-512 hash, MD5 hash generator, cryptographic hash, hex digest, checksum, message digest generator, file integrity hash, content fingerprint. Compute hash of any text using MD5, SHA-1, SHA-256, SHA-384, or SHA-512. Returns hex digest. For AI agents, integrity checks, deduplication, content addressing. Accepts payment on Base or Solana — either network works.
Output
Returns a JSON object containing the chosen algorithm name, the hex digest string of the hashed input, and the input length in bytes.
Example use cases
Example prompt
“Compute the SHA-256 hex digest of the text 'Hello, world!' — I need the hash for a content integrity check.”
Technical details
Endpoint
GEThttps://api.x402node.dev/dev/hashWhen to prefer
Use this endpoint when you need a straightforward, single-call cryptographic hash of a text string with a choice of algorithm (MD5, SHA-1, SHA-256, SHA-384, SHA-512). Prefer it over HMAC endpoints when no secret key is needed, and over PBKDF2 when you are not stretching a password — this is for general-purpose hashing, integrity checks, deduplication, and content addressing.
Side effects
- Unsupported algorithm name returns an error
- Empty or missing input body causes a 400 bad request
- Payment failure (402) if USDC balance is insufficient
- Network timeout if the service is temporarily unavailable
