SHA3-224 Hex Digest of Raw Hex Bytes
x402
SHA3-224 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-24).
Computes a SHA3-224 cryptographic hash of raw bytes provided as hex-encoded input, returning the digest as a hex string.

How this service works
Call when an agent needs a sha3-224 digest of hex bytes, encoded as hex. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-hex-rawhex first.
Output
A SHA3-224 cryptographic digest of the input hex bytes, returned as a lowercase hex string. The output is a fixed-length 56-character hexadecimal representation of the 224-bit hash.
Example use cases
Integrity fingerprint for binary payload
“I have a binary blob represented as hex — '4a6f686e446f65' — can you SHA3-224 hash it and return the hex digest so I can use it as an integrity fingerprint?”
Cryptographic commitment to hex-encoded data
“I need to create a SHA3-224 commitment to the hex string 'cafe0011beef9922' — please compute the digest as hex for me.”
Audit trail hashing for raw byte sequences
“For my audit log I need a SHA3-224 hex digest of the raw byte sequence '0011223344556677aabbccdd' — can you generate that?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-hex-rawhex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA3-224 (not SHA3-256, SHA-256, or MD5) digest of data already encoded as hexadecimal bytes, and you require the result as a hex string. Prefer the unpaid sandbox variant (POST /v1/sandbox/digest-sha3-224-hex-rawhex) when available to avoid the $0.007 USDC cost. Choose this paid endpoint when the sandbox is unavailable or rate-limited and you need a guaranteed response.
Side effects
- Invalid hex string input (non-hex characters) causing a parse error
- Input exceeds 100,000 character limit returning a validation error
- Missing required text or key field resulting in a 400 Bad Request
- Payment failure or insufficient USDC balance returning a 402 Payment Required
- Malformed request body returning a schema validation 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. |
