SHA3-384 Digest of UTF-16LE Bytes, Base64-Encoded
x402
SHA3-384 Digest of UTF-16LE Bytes, Base64-Encoded is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).
Computes a SHA3-384 cryptographic hash of a UTF-16LE encoded text string and returns it as a base64-encoded digest.

How this service works
Call when an agent needs a sha3-384 digest of utf16le bytes, encoded as base64. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base64-utf16 first.
Output
Returns a base64-encoded SHA3-384 digest computed from the UTF-16LE byte representation of the input text. The response provides a fixed-length cryptographic hash suitable for integrity verification, deduplication, or fingerprinting.
Example use cases
Data integrity fingerprint for pipeline
“I need to generate a SHA3-384 base64 fingerprint of the UTF-16LE encoded version of this document content so I can verify it hasn't been tampered with downstream: 'Annual report Q4 2024 revenue totals $4.2M net'.”
Deterministic ID from user input
“Take this user-submitted form text — 'John Doe, account #87234, preferences: dark mode' — and compute a SHA3-384 base64 hash over its UTF-16LE bytes so I can use it as a stable, collision-resistant identifier.”
Cross-system hash compatibility check
“Our Windows system produces SHA3-384 hashes over UTF-16LE encoded strings and encodes them in base64. Can you hash the string 'SyncToken:20240115-abc' the same way so I can compare outputs?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha3-384-base64-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a SHA3-384 hash computed over the UTF-16LE byte encoding of a string, with the result in base64 format — particularly when interoperating with Windows-native systems or other pipelines that use UTF-16LE encoding. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-384-base64-utf16) for development and testing before using this paid version.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or empty 'key' field may result in authentication failure
- Network or payment failure (x402) if USDC balance is insufficient
- Malformed JSON body returns a 400 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. |
