Blake2s-256 Hex Digest over UTF-16LE (agentshelf.syntexa.ch)
x402
Blake2s-256 Hex Digest over UTF-16LE (agentshelf.syntexa.ch) 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 BLAKE2s-256 cryptographic hash of a UTF-16LE-encoded string and returns the digest as a lowercase hex string.

How this service works
Call when an agent needs a blake2s256 digest of utf16le bytes, encoded as hex. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-hex-utf16 first.
Output
Returns a hex-encoded BLAKE2s-256 digest (64 hex characters) computed over the UTF-16LE byte representation of the input text, optionally keyed. The response is a deterministic, fixed-length hash string.
Example use cases
Keyed BLAKE2s hash for message authentication
“I need to authenticate a message — can you compute a BLAKE2s-256 hex digest of 'invoice:12345:approved' encoded as UTF-16LE using the secret key 'hmac-secret-42'?”
Content fingerprinting for deduplication
“I want a unique fingerprint for this document snippet to detect duplicates later. Can you get me the BLAKE2s-256 hex hash (UTF-16LE) of the text 'The quick brown fox jumps over the lazy dog'?”
Deterministic ID generation from Unicode text
“I need a stable, short ID derived from the Unicode string '2024年度レポート' — give me its BLAKE2s-256 hex digest over UTF-16LE bytes, no key needed.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-hex-utf16?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2s-256 digest over UTF-16LE-encoded bytes returned as hex — for example, when interoperating with Windows/.NET systems that default to UTF-16LE, or when your verification counterpart computes hashes over UTF-16LE. Prefer the free sandbox endpoint (/v1/sandbox/digest-blake2s256-hex-utf16) for testing. Use this paid endpoint for production workloads where the sandbox is unavailable or rate-limited.
Side effects
- Text or key exceeds maximum length (100,000 and 512 chars respectively) — returns a 4xx validation error
- Missing or empty text field — returns a 4xx validation error
- Payment not included or insufficient USDC — returns HTTP 402
- Malformed request body — returns a 4xx parse 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. |
