x402
SHA-512/224 Hex Digest (UTF-16LE) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).
Computes a SHA-512/224 hash of the input text encoded as UTF-16LE bytes and returns the digest as a lowercase hexadecimal string.

How this service works
Call when an agent needs a sha512-224 digest of utf16le bytes, encoded as hex. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-hex-utf16 first.
Output
Returns the SHA-512/224 cryptographic digest of the input text (interpreted as UTF-16LE bytes), encoded as a lowercase hexadecimal string. The output is a 56-character hex string representing the 224-bit hash value.
Example use cases
Integrity fingerprint for Windows file content
“I have a string 'Invoice-2024-Q1' that represents a Windows file name stored in UTF-16LE — can you compute its SHA-512/224 hash and give me the result as a hex string so I can use it as a compact integrity fingerprint?”
Keyed deduplication token for multilingual text
“I need a SHA-512/224 hex digest of the text '日本語テスト' encoded as UTF-16LE bytes — use 'dedup-key-01' as the key — so I can store a short, unique identifier for deduplication.”
Cross-platform hash verification for protocol compatibility
“Our legacy system hashes strings as UTF-16LE with SHA-512/224 and outputs hex — can you hash 'AuthToken::UserSession::9982' the same way so I can verify the two systems produce matching digests?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-224-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512/224 digest (the 224-bit truncated variant of SHA-512) computed over UTF-16LE encoded bytes and returned as hexadecimal. This is particularly useful for compatibility with Windows-native string encodings or legacy systems that store text as UTF-16LE. If you need a different hash algorithm, encoding (e.g. base64, base32), or character encoding (e.g. UTF-8, latin1), prefer the appropriate sibling endpoint. Try the free sandbox endpoint POST /v1/sandbox/digest-sha512-224-hex-utf16 first before paying.
Side effects
- Text or key exceeding maxLength (512 for key, 100000 for text) returns a validation error
- Empty string for text or key (minLength 1) returns a validation error
- Malformed request body returns a 400 error
- Payment failure or insufficient USDC balance returns a 402 error
- Service unavailability returns a 5xx 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. |
