SHA3-512 Hex Digest (UTF-16LE Encoding)
x402
SHA3-512 Hex 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).

How this service works
Call when an agent needs a sha3-512 digest of utf16le bytes, encoded as hex. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-hex-utf16 first.
Output
Returns a 128-character lowercase hexadecimal string representing the SHA3-512 digest of the input text after encoding it as UTF-16LE bytes. No network calls or LLM inference are performed; the result is deterministic and repeatable for the same input.
Example use cases
Document integrity fingerprinting
“Take this contract text and give me its SHA3-512 hex digest using UTF-16LE encoding so I can verify it hasn't been tampered with later.”
Password hashing pipeline
“Hash this passphrase 'CorrectHorseBatteryStaple' using SHA3-512 over UTF-16LE bytes and return the hex digest so I can store it securely.”
Deduplicate Unicode text records
“I have two copies of a Unicode document and want to know if they're identical — can you SHA3-512 hash each one as UTF-16LE and compare the hex digests?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-512-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA3-512 (not SHA2-512 or SHA3-256) applied to text interpreted as UTF-16LE bytes and want the result as a hex string. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-512-hex-utf16) first for testing. Use this paid version when the sandbox is unavailable or rate-limited.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing 'key' field may result in authentication or routing failure
- Malformed JSON body returns 400-level error
- Payment not included or insufficient USDC triggers 402 Payment Required
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. |
