x402
Blake2s-256 Hex Digest (Latin1) — agentshelf.syntexa.ch is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-29).

How this service works
Call when an agent needs a blake2s256 digest of latin1 bytes, encoded as hex. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-hex-latin1 first.
Output
A JSON response containing the BLAKE2s-256 digest of the provided latin1 text, encoded as a lowercase hexadecimal string. The digest is 32 bytes (64 hex characters) long.
Example use cases
Keyed message authentication code
“I need a keyed BLAKE2s-256 hex digest of the message 'order:12345:confirmed' using the key 'sharedSecret99' — can you compute that for me?”
Data integrity fingerprint
“Generate a BLAKE2s-256 hex fingerprint of this latin1-encoded config blob so I can verify it hasn't been tampered with: 'host=db.local;port=5432;db=prod'.”
Deterministic content hash
“Hash the latin1 text 'ñoño café' with blake2s256 and give me the hex output — no key needed, just a plain digest.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-hex-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2s-256 digest (not SHA-256 or BLAKE2b) of latin1-encoded text and want the result as hex. It supports optional keyed hashing (MAC mode) which SHA-family endpoints typically do not. Prefer the unpaid sandbox variant (/v1/sandbox/digest-blake2s256-hex-latin1) for testing; use this paid endpoint for production workloads where guaranteed SLA matters.
Side effects
- Text contains characters outside the latin1 range (codepoints > 255) — the API may reject or mangle the input
- Key exceeds 512-character maximum length — request rejected with validation error
- Empty text or key supplied — rejected by minLength:1 constraint
- Network timeout or service unavailability — no digest returned
- Insufficient USDC balance — payment fails and request is not processed
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. |
