SHA-512/224 Digest – Base64 Encoded, UTF-16LE Input
x402
SHA-512/224 Digest – Base64 Encoded, UTF-16LE Input is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).
Computes a SHA-512/224 cryptographic hash of text encoded as UTF-16LE bytes, returning the digest as a Base64 string.

How this service works
Call when an agent needs a sha512-224 digest of utf16le bytes, encoded as base64. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base64-utf16 first.
Output
Returns a Base64-encoded SHA-512/224 digest (28 bytes, 40-character Base64 string) computed over the UTF-16LE byte representation of the provided text.
Example use cases
Checksum for document integrity
“I need a SHA-512/224 digest of the text 'Annual Report Q4 2024 – Confidential' encoded as UTF-16LE, returned as Base64, so I can use it as a compact integrity checksum.”
Fingerprinting user-submitted content
“Hash this user comment 'Great product, would recommend!' using SHA-512/224 over its UTF-16LE bytes and give me the Base64 result so I can store a unique fingerprint.”
Generating a deterministic token from input
“Compute the SHA-512/224 Base64 digest of the UTF-16LE encoding of the string 'user:42:session:xyz' — I need a short deterministic token for deduplication.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-base64-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512/224 digest (the truncated variant of SHA-512) over UTF-16LE encoded bytes with Base64 output — useful for compatibility with Windows/COM systems that use UTF-16LE natively, or when interoperating with systems expecting this exact hash-encoding combination. If you don't need UTF-16LE byte semantics, prefer an endpoint using UTF-8 encoding instead.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid 'key' parameter causes a bad request
- Payment not provided or insufficient USDC balance results in a 402 Payment Required response
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. |
