x402
SHA3-224 Hex Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-01).
Computes a SHA3-224 cryptographic hash of input text and returns the result encoded as a hexadecimal string.

How this service works
Call when an agent needs a sha3-224 digest of text, encoded as hex. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-hex first.
Output
A hex-encoded SHA3-224 digest string (56 hex characters representing 224 bits) of the submitted text. The response is deterministic — the same input always produces the same digest. No network calls or LLM inference are involved in generation.
Example use cases
Data integrity fingerprinting
“Generate a SHA3-224 hex hash of this document content so I can use it as a checksum to verify nothing has changed later: 'Order ID: 98321, Amount: $150.00, Customer: Jane Doe'”
Deterministic ID generation
“I need a compact, fixed-length hex identifier derived from this URL string using SHA3-224: 'https://example.com/products/widget-blue-large'”
Password hashing for audit log
“Hash this plaintext token using SHA3-224 and return the hex digest so I can store a non-reversible record: 'session_token_abc123xyz'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-224 digest (Keccak-based, 224-bit output) returned in lowercase hexadecimal format. Prefer it over SHA2-224 when SHA-3 family resistance properties are required. Use the free sandbox endpoint (/v1/sandbox/digest-sha3-224-hex) first for testing. Choose a sibling endpoint if you need a different hash algorithm (MD5, RIPEMD-160, SHA-512) or a different output encoding (base32, base64, base64url).
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Invalid or missing API key results in a 402 Payment Required or authentication failure
- Malformed JSON body returns a 400 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. |
