x402
SHA3-224 Base64url Digest (UTF-16LE encoding) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-29).
Computes a SHA3-224 hash of text encoded as UTF-16LE bytes, returning the digest as a base64url string

How this service works
Call when an agent needs a sha3-224 digest of utf16le bytes, encoded as base64url. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base64url-utf16 first.
Output
Returns a base64url-encoded SHA3-224 digest computed over the UTF-16LE byte representation of the input text string
Example use cases
Document fingerprinting for deduplication
“I need a SHA3-224 base64url digest of this document text encoded as UTF-16LE bytes so I can detect duplicates: 'Annual report Q4 2024 revenue exceeded projections by 12%.'”
Integrity checksum for API payload
“Generate a SHA3-224 base64url hash of the UTF-16LE encoding of this JSON payload string so I can use it as a checksum: '{"user":"alice","amount":500}'”
Deterministic ID from user input
“Hash this user-submitted form value 'alice@example.com' using SHA3-224 over its UTF-16LE bytes and give me the base64url result so I can use it as a stable identifier.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-224-base64url-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-224 digest (not SHA-256, SHA3-256, or MD5) computed over UTF-16LE bytes (not UTF-8) and returned in base64url encoding — a combination important for interoperability with Windows-native or .NET systems that default to UTF-16LE. Use the free sandbox endpoint /v1/sandbox/digest-sha3-224-base64url-utf16 first for testing; fall back to this paid endpoint when the sandbox is unavailable.
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid 'key' field results in authentication failure
- Payment failure or insufficient USDC balance blocks the 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. |
