SHA-512/224 Digest of Hex Bytes, Base64-Encoded
x402
SHA-512/224 Digest of Hex Bytes, Base64-Encoded is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-29).
Computes a SHA-512/224 cryptographic hash of raw bytes supplied as a hex string and returns the digest encoded in base64.

How this service works
Call when an agent needs a sha512-224 digest of hex bytes, encoded as base64. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base64-rawhex first.
Output
Returns a base64-encoded SHA-512/224 cryptographic digest of the input hex bytes. The SHA-512/224 algorithm produces a 224-bit (28-byte) hash truncated from SHA-512, which base64-encodes to approximately 40 characters.
Example use cases
Verify binary file integrity
“I have a binary chunk represented as hex — '4d5a9000' — can you hash it with SHA-512/224 and give me the base64 digest so I can compare it against a stored checksum?”
Short hash for compact storage
“I need a compact cryptographic digest of some raw bytes I have in hex format. Can you run SHA-512/224 on 'cafebabe1234' and return the base64 result? I want to store it efficiently.”
Cryptographic integrity tag for protocol message
“Our protocol requires a SHA-512/224 hash of the raw message bytes, encoded as base64. The message bytes in hex are 'ff00aabb'. Can you compute that for me?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-base64-rawhex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512/224 hash (the 224-bit truncated variant of SHA-512) over SHA-256 or SHA-3 variants, and your input is raw binary data represented as a hex string rather than plain text, with the output needed in base64 encoding. If you need to hash plain text rather than hex bytes, use the text-input sibling endpoint instead. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha512-224-base64-rawhex) before paying.
Side effects
- Invalid hex string (odd length or non-hex characters) — likely returns a 400 error
- Input exceeds maxLength of 100,000 characters — request rejected
- Empty input string — rejected due to minLength:1 constraint
- Network timeout or service unavailability — 5xx error
- Insufficient USDC balance for the $0.006 payment — payment failure
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. |
