SHA3-384 Hex-Bytes-to-Hex Digest
x402
SHA3-384 Hex-Bytes-to-Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-24).
Computes a SHA3-384 cryptographic hash of raw hex-encoded input bytes and returns the digest as a hex string

How this service works
Call when an agent needs a sha3-384 digest of hex bytes, encoded as hex. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-hex-rawhex first.
Output
Returns a SHA3-384 cryptographic digest of the raw bytes represented by the hex-encoded input, as a lowercase hexadecimal string. No additional metadata — just the hex-encoded hash output.
Example use cases
Binary data integrity verification
“I have a binary blob stored as hex — 'deadbeef0102030405' — can you run SHA3-384 on those raw bytes and give me the hex digest so I can compare it against the expected checksum?”
Cryptographic fingerprinting of byte sequences
“I need to fingerprint this raw byte sequence for my audit log. The bytes are hex-encoded: 'cafebabe00010002'. Please hash them with SHA3-384 and return the result as hex.”
Deterministic hash for protocol message
“My protocol needs a SHA3-384 hex digest of the raw bytes 'f0e1d2c3b4a59687' to include in a signed message header — can you compute that for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-384-hex-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to hash raw binary data that is already hex-encoded (i.e. the input is hex bytes, not UTF-8 text) and want the SHA3-384 output as a hex string. Use the free sandbox endpoint POST /v1/sandbox/digest-sha3-384-hex-rawhex first if available; only call this paid endpoint when the sandbox is unavailable or you need production-grade reliability. Prefer this over SHA2/MD5/BLAKE2 siblings when SHA3-384 strength is required by your protocol or compliance requirements.
Side effects
- Invalid hex input (non-hex characters in the text field) returns an error
- Input exceeds 100,000 character limit causing rejection
- Missing or empty 'text' or 'key' fields return validation errors
- Payment of exactly $0.001 USDC not provided results in 402 Payment Required
- Network timeout or service unavailability returns 5xx error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
