x402
SHA3-224 Hex Digest (UTF-16LE) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-24).
Computes a SHA3-224 hash of the UTF-16LE byte encoding of a given text string, returning the result as a lowercase hex string.

How this service works
Call when an agent needs a sha3-224 digest of utf16le bytes, encoded as hex. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-hex-utf16 first.
Output
Returns a lowercase hex-encoded SHA3-224 digest (56 hex characters) computed over the UTF-16LE byte representation of the input text. The response includes the hash string corresponding to the submitted text.
Example use cases
Data integrity fingerprinting
“I need a SHA3-224 hex hash of the text 'Invoice #4821 total: $1,250.00' using UTF-16LE encoding so I can store a tamper-evident fingerprint of this record.”
Unicode content checksum
“Can you give me the SHA3-224 hex digest of this Japanese string '日本語テスト' encoded as UTF-16LE? I want to verify the content hasn't changed.”
Deterministic identifier generation
“Hash the string 'user:alice@example.com:2024' with SHA3-224 using UTF-16LE bytes and return the hex result — I'll use it as a deterministic unique identifier.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA3-224 (not SHA-256, SHA3-256, or other variants) with UTF-16LE byte encoding — common for compatibility with Windows/.NET systems that default to UTF-16LE. If you don't need the paid version, prefer the unpaid sandbox endpoint POST /v1/sandbox/digest-sha3-224-hex-utf16 first. Use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing 'key' parameter may cause authentication failure
- Payment of $0.005 USDC not included or declined results in HTTP 402
- Malformed JSON request 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. |
