SHA-384 Digest (UTF-16LE → Base64)
x402
SHA-384 Digest (UTF-16LE → Base64) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).
Computes a SHA-384 hash of text encoded as UTF-16LE bytes and returns the digest as a Base64 string.

How this service works
Call when an agent needs a sha384 digest of utf16le bytes, encoded as base64. Send JSON {"text":"hello"}. Exact $0.01 USDC on Base. Try unpaid POST /v1/sandbox/digest-sha384-base64-utf16 first.
Output
Returns a Base64-encoded SHA-384 digest of the input text after encoding it as UTF-16LE bytes. The result is a fixed-length cryptographic hash string suitable for integrity checking or fingerprinting.
Example use cases
Integrity fingerprint for document content
“I need to generate a SHA-384 Base64 fingerprint of this contract text using UTF-16LE encoding so I can verify it hasn't been tampered with later: 'This agreement is entered into on January 1, 2025...'”
Cross-platform checksum for Unicode strings
“Can you hash the string 'Ünïcödé tëxt sämplé' with SHA-384 using UTF-16LE bytes and return the Base64 digest? I need it to match what a Windows app produces.”
Deterministic token generation from a passphrase
“Take the phrase 'mysecretpassphrase2025' and compute its SHA-384 hash as Base64, treating the text as UTF-16LE bytes — I'm building a deterministic token.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-base64-utf16?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need a SHA-384 hash of text that has been encoded as UTF-16LE bytes (common in Windows/COM environments) and the output must be Base64 encoded. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha384-base64-utf16) for testing. Choose this over sibling endpoints when SHA-384 strength is required over MD5, SHA-1, or RIPEMD-160, and Base64 output is needed rather than hex or base64url.
Side effects
- Text exceeds 100,000 character limit — request rejected
- Text or key field is empty or missing — validation error
- Invalid UTF-16LE encoding edge cases for certain characters
- Payment of exactly $0.01 USDC not fulfilled — 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. |
