x402
SHA-512 Base64url Digest of UTF-16LE Encoded Text is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-29).

How this service works
Call when an agent needs a sha512 digest of utf16le bytes, encoded as base64url. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-base64url-utf16 first.
Output
A base64url-encoded SHA-512 digest string computed from the input text after encoding it as UTF-16LE bytes. The response contains the hash value that can be used for integrity verification, fingerprinting, or comparison with hashes produced by UTF-16LE-aware systems such as .NET or Windows applications.
Example use cases
Verify Windows/.NET string fingerprint
“I need a SHA-512 hash of the string 'invoice-2024-001-approved' encoded as UTF-16LE bytes and returned as base64url — that's how our .NET backend computes its checksums.”
Content integrity token for Unicode text
“Generate a SHA-512 base64url digest of this Japanese text '日本語のテスト文字列' using UTF-16LE encoding so I can include it as an integrity token in a document header.”
Cross-platform hash matching
“Can you compute the SHA-512 hash of 'the quick brown fox jumps over the lazy dog' treating the text as UTF-16LE bytes and encoding the output as base64url? I need to confirm it matches what a Windows application produced.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha512-base64url-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-512 hash of text that has been encoded as UTF-16LE bytes (as used by Windows, .NET, and Microsoft ecosystems) with the output in base64url format. Prefer this over SHA-256 or SHA-3 variants when interoperating with systems that use UTF-16LE string encoding natively. Use the sandbox variant (/v1/sandbox/digest-sha512-base64url-utf16) for testing to avoid the $0.005 USDC charge.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field returns a validation error
- Invalid USDC payment or insufficient funds results in 402 Payment Required
- Network timeout if the service is temporarily unavailable
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. |
