BLAKE2s-256 Hash Digest
x402
BLAKE2s-256 Hash Digest 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 a BLAKE2s-256 cryptographic hash digest from either a UTF-8 text string or raw hex-encoded bytes

How this service works
BLAKE2s-256 digest of text or raw bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok:true, the hash type ('hash-blake2s256'), and a receipt object containing the transaction hash, USD amount charged, and a unique receipt ID. The BLAKE2s-256 digest itself is included in the response alongside generation timestamp.
Example use cases
Data integrity check before upload
“Hash this string using BLAKE2s-256 so I can store the digest alongside my file and verify it hasn't been tampered with later: 'user-session-token-abc123xyz'”
Hashing raw bytes for blockchain
“I have some raw hex-encoded bytes 0x4a6f686e446f65 — can you run them through BLAKE2s-256 and give me the digest?”
Deriving a deterministic key from input
“Compute the BLAKE2s-256 digest of the text 'my-app:user:42:secret' so I can use it as a deterministic identifier in my smart contract.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/hash-blake2s256?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a BLAKE2s-256 hash specifically — preferred for speed-sensitive or resource-constrained environments where BLAKE2s (32-byte output, optimized for 32-bit platforms) is the required algorithm. Use over SHA-256 or BLAKE2b when the target system or protocol explicitly specifies BLAKE2s-256, such as certain blockchain protocols, zero-knowledge proof systems, or embedded contexts. Suitable for both text and binary (hex-encoded) inputs.
Side effects
- Input exceeds 49152 character limit for text — returns validation error
- Hex string does not match pattern ^0x[0-9a-fA-F]*$ — returns schema validation error
- Both hex and text fields omitted — ambiguous or empty input error
- Payment failure via x402 protocol — endpoint returns 402 before processing
- Network timeout on the UnyKorn node — returns gateway error
