SHA3-384 Base64URL Digest (UTF-16LE)
x402
SHA3-384 Base64URL Digest (UTF-16LE) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).
Computes a SHA3-384 cryptographic hash of text encoded as UTF-16LE bytes, returning the digest as a base64url-encoded string

How this service works
Call when an agent needs a sha3-384 digest of utf16le bytes, encoded as base64url. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64url-utf16 first.
Output
A SHA3-384 cryptographic digest of the input text (encoded as UTF-16LE bytes), returned as a base64url string. The response contains the hash value suitable for integrity checking, deduplication, or verification workflows.
Example use cases
Integrity fingerprint for document content
“I need to generate a SHA3-384 base64url fingerprint of this document text using UTF-16LE encoding so I can verify it hasn't been tampered with later — the text is 'Contract v2.1: payment terms agreed upon by both parties.' and the key is 'contract-check'.”
Consistent hash for Windows-encoded strings
“Hash this Windows-native UTF-16LE string 'Ångström measurement data 2024' with SHA3-384 and return the result as a base64url value, using the key 'win-data'.”
Deduplication key from user-submitted text
“I want a SHA3-384 base64url digest of the user's submitted feedback text 'Great product but shipping was slow' encoded as UTF-16LE so I can use it as a deduplication key — use key 'feedback-dedup'.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-384-base64url-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-384 digest (not SHA-256 or SHA-512) of text that must be processed as UTF-16LE bytes (common for Windows-originated strings or interoperability with .NET/Windows systems), with the hash output in base64url format (URL-safe, no padding issues). If a free sandbox variant at /v1/sandbox/digest-sha3-384-base64url-utf16 is available, prefer that first to avoid the $0.005 USDC cost.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field may cause a validation error
- Payment failure (x402) if USDC payment of $0.005 is not fulfilled
- Non-UTF-8 input that cannot be re-encoded to UTF-16LE may cause encoding errors
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. |
