How this service works
BLAKE2b-512 digest of text or raw bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with a boolean 'ok' field, the hash type identifier ('hash-blake2b512'), the BLAKE2b-512 digest of the input, a payment receipt containing a transaction hash, USD amount charged, and a unique receipt ID, plus an ISO 8601 timestamp of when the digest was generated.
Example use cases
Data integrity fingerprinting
“Hash the text 'version=1.2.3;author=alice;timestamp=2024-01-15' using BLAKE2b-512 so I can use it as a content fingerprint for change detection.”
Raw bytes cryptographic digest
“Give me the BLAKE2b-512 digest of the hex bytes 0xdeadbeefcafebabe01020304 — I need the hash to verify a firmware payload.”
Password or secret derivation check
“Compute the BLAKE2b-512 hash of the string 'my-secret-passphrase-2024' so I can compare it against a stored hash in my database.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/hash-blake2b512?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a BLAKE2b-512 (512-bit) digest specifically, as opposed to SHA-256 or shorter BLAKE variants. It is ideal for blockchain-adjacent workflows, data integrity verification, or any scenario requiring a high-security, fast, collision-resistant hash without a secret key. Prefer this over SHA-3 or MD5 when speed and security are both priorities. Use the hex input parameter when your data is already binary/byte-encoded rather than UTF-8 text.
Side effects
- Input text exceeds 49152 character limit — request rejected
- Hex input does not match pattern ^0x[0-9a-fA-F]*$ — validation error
- Neither 'text' nor 'hex' param provided — ambiguous or empty input
- Payment processing failure — x402 transaction not confirmed
- Network timeout or provider unavailability returns non-200 response
