SHA-512 Hex Digest (UTF-16LE Encoding)
x402
SHA-512 Hex Digest (UTF-16LE Encoding) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-09-29).
Computes a SHA-512 hash of 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 digest of utf16le bytes, encoded as hex. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-hex-utf16 first.
Output
Returns a hex-encoded SHA-512 digest string computed from the UTF-16LE byte representation of the input text. The output is a 128-character lowercase hexadecimal string uniquely representing the hashed content.
Example use cases
Verify file integrity via hash
“Hash this document content using SHA-512 with UTF-16LE encoding and return the hex digest so I can check it against my expected checksum: 'Invoice #4521 total $3,200.00 due 2024-06-01'”
Generate password hash for Windows compatibility
“I need to compute the SHA-512 hex hash of the password 'S3cur3P@ssw0rd!' encoded as UTF-16LE bytes — this is for a Windows-compatible credential hash.”
Fingerprint Unicode text for deduplication
“Can you produce a SHA-512 hex fingerprint of this Japanese text '日本語のテキスト' using UTF-16LE encoding so I can use it as a unique identifier in my database?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SHA-512 hashing where the input text must be processed as UTF-16LE bytes (common in Windows environments, .NET, or when interoperating with systems that use wide-character encoding). Prefer the free sandbox endpoint (/v1/sandbox/digest-sha512-hex-utf16) for testing. Use sibling endpoints if you need a different output encoding (base32, base64, base64url) or a different character encoding (plain UTF-8 text vs UTF-16LE bytes).
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field returns an authentication/validation error
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Malformed request body returns 400 Bad 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. |
