SHA-384 Hex Digest of Raw Hex Bytes
x402
SHA-384 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-09-29).
Computes a SHA-384 digest of raw bytes supplied as a hex string, returning the result encoded as a hex string.

How this service works
Call when an agent needs a sha384 digest of hex bytes, encoded as hex. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-hex-rawhex first.
Output
Returns a hex-encoded SHA-384 digest computed over the raw bytes represented by the input hex string. The output is a 96-character lowercase hex string corresponding to the 48-byte SHA-384 hash.
Example use cases
Integrity check for binary blob
“I have a binary payload stored as hex — '4f3a9c8b...' — can you run SHA-384 over those raw bytes and return the hex digest so I can compare it against the expected checksum?”
Cryptographic fingerprint for audit log
“For my audit log entry, compute the SHA-384 hex digest of this hex-encoded byte sequence: 'aabbccdd1122334455' — I need the raw-bytes hash, not a string hash.”
Hashing serialized binary protocol data
“I have a binary message from a network protocol serialized as hex ('0800450000...'), and I need its SHA-384 digest as hex to include in the message signature — can you compute that?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-hex-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA-384 applied to raw bytes that are supplied in hexadecimal encoding, and you need the output also as hex. Use the free sandbox endpoint (POST /v1/sandbox/digest-sha384-hex-rawhex) first for testing. Prefer this over SHA-256 or SHA-512 endpoints when SHA-384 is required by your protocol or compliance requirement.
Side effects
- Input 'text' is not valid hex — returns error indicating malformed hex input
- Input exceeds 100,000 character limit — request rejected
- Missing required fields ('key' or 'text') — validation error
- Payment of $0.009 USDC not provided or insufficient — 402 Payment Required
- Odd-length hex string may fail raw byte decoding
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. |
