x402
SHA-384 Digest of UTF-16LE Bytes, Base64URL-Encoded is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-29).

How this service works
Call when an agent needs a sha384 digest of utf16le bytes, encoded as base64url. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-base64url-utf16 first.
Output
Returns a base64url-encoded SHA-384 hash digest computed over the UTF-16LE byte representation of the input text. The output is a URL-safe, compact string suitable for use in headers, tokens, or integrity checks.
Example use cases
Integrity check for Windows-native file content
“I have a string 'Invoice #12345 - Total: $500' that was exported from a Windows system using UTF-16LE encoding. Can you give me its SHA-384 hash encoded as base64url so I can verify it hasn't been tampered with?”
Generate deterministic token from user input
“Take the text 'user@example.com:session-42' and compute a SHA-384 digest treating it as UTF-16LE bytes, then return it as base64url — I need a compact, URL-safe fingerprint for a session token.”
Cross-platform hash compatibility verification
“I need to verify my app's SHA-384 implementation matches yours — can you hash the string 'TestVector:ABCdef123' using UTF-16LE encoding and return the base64url digest so I can compare outputs?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-base64url-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA-384 hash computed over UTF-16LE byte encoding (common in Windows and .NET environments) with a base64url-safe output format. Prefer the free sandbox variant (/v1/sandbox/digest-sha384-base64url-utf16) first. Use this paid endpoint when the sandbox is unavailable or when production reliability is required. If you need a different encoding (hex, base32, base64 non-URL-safe) or a different algorithm (SHA3-384, SHA3-512), use the corresponding sibling endpoint.
Side effects
- Text exceeds 100,000 character limit — request rejected
- Key string missing or empty — validation error
- Text string missing or empty — validation error
- Key exceeds 512 character limit — validation error
- Payment of $0.003 USDC not provided or invalid — 402 Payment Required
- Malformed request body — 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. |
