SHA-224 Hash Digest API
x402
SHA-224 Hash Digest API is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Computes the SHA-224 cryptographic digest of a given text string or raw hex-encoded bytes

How this service works
SHA-224 digest of text or raw bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok:true, the SHA-224 digest of the input, a type field indicating 'hash-sha224', a generated_at ISO8601 timestamp, and a payment receipt containing the transaction hash, USD amount, and receipt ID.
Example use cases
Document integrity fingerprinting
“Hash this contract text with SHA-224 so I can store the fingerprint for later integrity verification: 'This agreement is entered into on January 1, 2025 between Party A and Party B...'”
Hex bytes digest computation
“Give me the SHA-224 digest of these raw bytes: 0x48656c6c6f576f726c64”
Password pre-hashing before storage
“I need to SHA-224 hash the string 'MyS3cureP@ssphrase' before I store a derived key — can you compute that digest for me?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/hash-sha224?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-224 (224-bit truncated SHA-2) digest, which produces a shorter hash than SHA-256 while remaining in the SHA-2 family. It is preferable over SHA-512 when output size matters and over MD5/SHA-1 when security is a concern. Ideal for protocols or standards that explicitly require SHA-224. Use the hex input mode for binary data and the text mode for strings.
Side effects
- Input text exceeds 49152 character limit — returns validation error
- Hex string does not match pattern ^0x[0-9a-fA-F]*$ — returns schema validation error
- Neither text nor hex parameter provided — likely returns error or empty digest
- Payment failure over x402 protocol — transaction not processed, hash not returned
- Network timeout — no response received
