SHA3-512 Hash Digest
x402
SHA3-512 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 SHA3-512 cryptographic hash digest from either a UTF-8 text string or raw bytes provided as a hex-encoded input

How this service works
SHA3-512 digest of text or raw bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok:true, the hash type ('hash-sha3-512'), the computed SHA3-512 digest value, and a payment receipt containing a transaction hash, USD amount charged, and a unique receipt ID.
Example use cases
Data integrity fingerprinting
“Compute the SHA3-512 hash of the text 'The quick brown fox jumps over the lazy dog' so I can use it as a fingerprint to verify the data hasn't been tampered with.”
Hashing raw hex-encoded bytes
“Give me the SHA3-512 digest of these raw bytes: 0xdeadbeefcafe1234 — I need to verify the integrity of a binary payload.”
Blockchain commitment hashing
“Hash the string 'user-commitment-2024-abc123' with SHA3-512 so I can use it as a cryptographic commitment on-chain.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/hash-sha3-512?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA3-512 (not SHA2-512, MD5, or SHA-256) cryptographic digest, especially for blockchain-adjacent applications, smart contract commitments, or any use case mandating the SHA3/Keccak family. It accepts both raw text and hex-encoded binary input, making it versatile. Prefer this over general-purpose hashing services when you need a pay-per-call, auditable receipt with transaction proof.
Side effects
- Input text exceeds 49152 character limit — request rejected
- Hex string does not match pattern ^0x[0-9a-fA-F]*$ — invalid format error
- Neither 'text' nor 'hex' parameter provided — missing input error
- Payment failure via x402 protocol — 402 Payment Required response
- Network timeout or service unavailability from the UnyKorn operator node
