SHA-384 Hash Digest
x402
SHA-384 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 the SHA-384 cryptographic digest of either a UTF-8 text string or raw bytes provided as a hex-encoded value

How this service works
SHA-384 digest of text or raw bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok=true, the hash type ('hash-sha384'), the SHA-384 digest value, and a payment receipt including transaction hash, USD amount charged, and a unique receipt ID.
Example use cases
Document integrity fingerprint
“Hash this contract text with SHA-384 so I can store a tamper-proof fingerprint of it: 'This agreement is entered into on June 1, 2025 between Acme Corp and...'”
Blockchain payload pre-image hash
“I need the SHA-384 digest of these raw bytes before I submit them on-chain — the hex is 0x4a3f2c1d.”
Password-free verification token
“Take the string 'user:alice:session:20250601' and give me its SHA-384 digest so I can use it as a verification token.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/hash-sha384?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, trustless SHA-384 hash via the x402 micropayment protocol without managing your own crypto infrastructure. Prefer it over SHA-256 endpoints when 384-bit digest strength is required (e.g. TLS certificate chains, NIST compliance). Useful for agents that need on-demand hashing within an automated blockchain or EVM workflow on the UnyKorn network.
Side effects
- Input exceeds 49152 character limit for text — returns validation error
- Hex input does not match pattern ^0x[0-9a-fA-F]*$ — returns schema validation error
- Payment failure via x402 protocol — call not executed
- Neither 'text' nor 'hex' param provided — ambiguous or empty input error
- Network timeout on the UnyKorn operator node
