x402
SHA3-224 Base64 Digest (UTF-16LE Encoding) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-29).
Computes a SHA3-224 hash of the input text encoded as UTF-16LE bytes, returning the digest as a base64 string

How this service works
Call when an agent needs a sha3-224 digest of utf16le bytes, encoded as base64. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base64-utf16 first.
Output
Returns a base64-encoded string representing the SHA3-224 digest of the input text after encoding it as UTF-16LE bytes. The digest is deterministic and fixed-length for any given input.
Example use cases
Integrity check for document content
“I need to generate a SHA3-224 base64 digest of this contract text using UTF-16LE encoding so I can verify it hasn't been tampered with later: 'This agreement is entered into on January 1, 2025 between Party A and Party B.'”
Fingerprinting multilingual user input
“Can you hash this Japanese text '日本語テキスト' using SHA3-224 with UTF-16LE byte encoding and return the result as base64? I need the fingerprint to deduplicate submissions.”
Generating reproducible content identifiers
“Hash the string 'product-sku-AX900-variant-blue' with SHA3-224 via UTF-16LE encoding and give me the base64 output so I can use it as a stable content identifier in my database.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-base64-utf16?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA3-224 digest computed over UTF-16LE byte encoding of the input text, with the result returned as base64. This is distinct from SHA3-256 or other SHA3 variants, and from UTF-8 encoding. If you need SHA3-224 base64 without payment, try the unpaid sandbox variant at /v1/sandbox/digest-sha3-224-base64-utf16 first.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid 'key' field may result in authentication failure
- Payment of $0.008 USDC not provided results in 402 Payment Required
- Malformed request body returns 400 Bad Request
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. |
