SHA-512/224 Digest — Base64URL + UTF-16LE Encoding
x402
SHA-512/224 Digest — Base64URL + UTF-16LE Encoding is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-19).
Computes a SHA-512/224 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 sha512-224 digest of utf16le bytes, encoded as base64url. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base64url-utf16 first.
Output
Returns a base64url-encoded SHA-512/224 digest of the input text treated as UTF-16LE bytes. The output is a compact, URL-safe cryptographic hash string suitable for integrity checks, deduplication keys, or content identifiers.
Example use cases
Integrity fingerprint for a log entry
“I need a SHA-512/224 base64url fingerprint of this log line encoded as UTF-16LE: 'User admin logged in at 2024-06-01T12:00:00Z'. Can you compute that?”
Deterministic ID for a document chunk
“Generate a base64url SHA-512/224 hash of this text chunk using UTF-16LE encoding so I can use it as a stable content identifier: 'The quick brown fox jumps over the lazy dog.'”
Verifying data integrity across systems
“Can you compute the SHA-512/224 digest of 'order:98765:confirmed:2024' using UTF-16LE bytes and return it as a base64url string so I can cross-check it against the value my partner system produced?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-base64url-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512/224 hash (not SHA-256 or SHA-512) with UTF-16LE byte encoding and base64url output encoding — a combination common in Windows-ecosystem compatibility, certain token-generation schemes, or when an existing system already uses this exact algorithm and encoding triple. If you only need a generic hash or a different encoding (e.g. hex, base64 standard), a different endpoint is more appropriate.
Side effects
- Text or key field missing or empty — validation error returned
- Text exceeds 100,000 character limit — request rejected
- Key string exceeds 512 character limit — request rejected
- Payment of $0.007 USDC not provided or declined — 402 response
- Malformed JSON body — parse error returned
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. |
