SHA3-512 Digest of UTF-16LE Bytes, Base64-Encoded
x402
SHA3-512 Digest of UTF-16LE Bytes, Base64-Encoded 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 SHA3-512 cryptographic hash of text encoded as UTF-16LE bytes and returns the result as a Base64 string.

How this service works
Call when an agent needs a sha3-512 digest of utf16le bytes, encoded as base64. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-base64-utf16 first.
Output
Returns a Base64-encoded SHA3-512 cryptographic digest computed over the UTF-16LE byte representation of the input text. The output is a fixed-length Base64 string corresponding to the 512-bit hash.
Example use cases
Integrity check for Windows file content
“I have a string that was saved on a Windows system — treat it as UTF-16LE bytes, run SHA3-512 on it, and give me the base64 digest so I can verify it hasn't been tampered with. The text is 'C:\Users\alice\report.docx v2 final'.”
Cross-platform hash verification
“I need to verify that a document matches a SHA3-512 checksum someone gave me — can you hash the text 'Invoice #4821 Total: $3,500.00' as UTF-16LE bytes and return the result in base64 so I can compare it?”
Generating a deterministic token from UTF-16LE text
“Take the string 'session-user-42-secret' and produce a SHA3-512 base64 digest treating it as UTF-16LE bytes — I want to use this as a deterministic fingerprint for an audit log.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-512-base64-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-512 hash computed over UTF-16LE byte encoding (common in Windows/Microsoft environments) with Base64 output format. Prefer the unpaid sandbox endpoint /v1/sandbox/digest-sha3-512-base64-utf16 for testing. Use this paid endpoint when the sandbox is unavailable or when production-grade reliability is required. If you need SHA3-512 over plain UTF-8 or different output encodings (hex, base64url), look for sibling endpoints on agentshelf.syntexa.ch.
Side effects
- Input text is empty or missing — returns validation error
- Text exceeds 100,000 character limit — request rejected
- Key parameter is missing or empty — returns error
- Malformed request body — returns HTTP 400
- Payment of $0.004 USDC not provided or rejected — returns HTTP 402
- Service temporarily unavailable — returns HTTP 5xx
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. |
