SHA-384 Hex Digest of UTF-16LE Encoded Text
x402
SHA-384 Hex Digest of UTF-16LE Encoded Text is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-02).
Computes a SHA-384 cryptographic hash of the UTF-16LE byte representation of input text and returns it as a lowercase hex string

How this service works
Call when an agent needs a sha384 digest of utf16le bytes, encoded as hex. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-sha384-hex-utf16 first.
Output
Returns a lowercase hexadecimal string representing the SHA-384 cryptographic digest of the input text after it has been encoded as UTF-16LE bytes. The digest is 96 hex characters long (384 bits).
Example use cases
Checksum for API payload integrity
“I need to verify the integrity of this API payload — compute the SHA-384 hex digest of its UTF-16LE bytes using key 'api-integrity-check' and the text '{"userId":42,"action":"transfer"}'.”
Fingerprinting multilingual document content
“Generate a SHA-384 hex fingerprint of the UTF-16LE encoding of this Japanese document excerpt '日本語テスト文書' using key 'doc-fingerprint' so I can detect future changes.”
Consistent cross-platform hash for Windows-encoded strings
“Give me the SHA-384 hash in hex of the UTF-16LE bytes for the string 'Windows encoded config value: path=C:\Users\Admin' with key 'config-hash', since our Windows system uses UTF-16LE natively.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha384-hex-utf16?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need SHA-384 (not SHA-256 or SHA-512) applied to the UTF-16LE byte encoding of a string (common in Windows/.NET environments or when interoperating with systems that use UTF-16LE natively). Choose this over generic hashing libraries when you need a paid, auditable, API-based computation without running local code. If a free sandbox endpoint (POST /v1/sandbox/digest-sha384-hex-utf16) is available, prefer that first to avoid the $0.007 charge.
Side effects
- Text exceeds maximum length of 100,000 characters — request rejected
- Key string is empty or exceeds 512 characters — validation error
- Malformed JSON body — 400 bad request
- Payment not attached or insufficient USDC — 402 payment required
- Service temporarily unavailable — 503 error
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. |
