SHA-512/224 Hex Digest of Raw Hex Bytes
x402
SHA-512/224 Hex Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-19).
Computes a SHA-512/224 hash of input interpreted as raw hex bytes and returns the digest encoded as a hexadecimal string.

How this service works
Call when an agent needs a sha512-224 digest of hex bytes, encoded as hex. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-hex-rawhex first.
Output
Returns a hex-encoded SHA-512/224 digest string computed over the input interpreted as raw hex bytes. The digest is a fixed-length hexadecimal string (56 hex characters / 28 bytes).
Example use cases
Integrity check of binary payload
“I have binary data encoded as hex — '48656c6c6f576f726c64' — can you run SHA-512/224 on those raw bytes and return the hex digest so I can verify its integrity?”
Keyed hash for hex-encoded data
“Compute a SHA-512/224 hex digest of the hex string 'deadbeefcafe0123' using the key 'mysecretkey' so I can use it for a checksum in my pipeline.”
Cryptographic fingerprint generation
“Generate a SHA-512/224 hash of the hex-encoded bytes 'a1b2c3d4e5f6' and return it as hex — I need a compact cryptographic fingerprint for this chunk of data.”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-hex-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512/224 digest of data that is already hex-encoded (i.e., the input represents raw bytes in hex form) and you need the output in hex format. Use this over SHA-256 or full SHA-512 when a 224-bit truncated digest is required for compatibility with systems using the SHA-512/224 standard. Try the free sandbox endpoint POST /v1/sandbox/digest-sha512-224-hex-rawhex first if available before paying.
Side effects
- Invalid hex string input (odd-length or non-hex characters) causing a 400 error
- Input text exceeding 100,000 character limit
- Key exceeding 512 character limit
- Payment failure or insufficient USDC balance triggering a 402 error
- Network timeout or service unavailability returning a 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. |
