SHA-224 Hex Digest
x402
SHA-224 Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-01).
Computes the SHA-224 cryptographic hash of input text and returns it as a hexadecimal-encoded digest string.

How this service works
Call when an agent needs a sha224 digest of text, encoded as hex. No network and no LLM. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha224-hex first.
Output
Returns a 56-character lowercase hexadecimal string representing the SHA-224 digest of the submitted text. No external network calls or LLM inference are involved — the computation is deterministic and pure.
Example use cases
Deduplication fingerprint for documents
“I need a unique fingerprint for this text so I can detect duplicates in my database — can you compute the SHA-224 hex hash of 'The quick brown fox jumps over the lazy dog'?”
Integrity checksum for API payloads
“Generate a SHA-224 hex digest of this JSON payload string so I can attach it as a content checksum before sending it to a third-party service: '{"user":"alice","action":"login","timestamp":1700000000}'”
Deterministic ID from user input
“I want to turn the user's email address 'jane.doe@example.com' into a deterministic 56-character hex ID — compute the SHA-224 hash of that string for me.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha224-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a compact, deterministic SHA-224 hash of text returned as hex (56 hex characters). Prefer the free sandbox endpoint (/v1/sandbox/digest-sha224-hex) for testing. Use this paid endpoint in production when you need reliable uptime. Choose SHA-224 hex over SHA-224 base64 when downstream systems expect hexadecimal encoding. Prefer SHA-256 or SHA-3 endpoints if a longer or different digest algorithm is required.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key returns an authentication error
- Malformed JSON request body causes a 400 bad request
- Payment not provided or insufficient funds returns a 402 Payment Required
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. |
