x402
BLAKE2b-512 Digest with Base64 Encoding (Latin1 Input) 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 keyed BLAKE2b-512 cryptographic hash of Latin1-encoded text and returns the digest as a Base64 string.

How this service works
Call when an agent needs a blake2b512 digest of latin1 bytes, encoded as base64. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2b512-base64-latin1 first.
Output
A Base64-encoded string representing the 512-bit BLAKE2b cryptographic digest of the provided Latin1 text, computed with the given key.
Example use cases
Message authentication code generation
“Hash this Latin1-encoded payment payload 'montant=100,devise=EUR,bénéficiaire=Dupont' using the key 'pay-hmac-secret' with BLAKE2b-512 and return it as Base64 so I can attach it as a MAC.”
File integrity checksum for Latin1 content
“I have a Latin1-encoded config file content: 'paramètre=activé;niveau=élevé'. Compute its keyed BLAKE2b-512 digest using key 'cfg-integrity-key' and give me the base64 hash so I can store it for integrity verification.”
Deterministic token derivation
“Derive a BLAKE2b-512 base64 digest from the Latin1 string 'utilisateur=René;session=42' with key 'token-derive-key' — I need this as a deterministic session token fingerprint.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2b512-base64-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2b-512 digest (not SHA-256, MD5, or other algorithms) of Latin1-encoded text, returned as Base64. Prefer the unpaid sandbox endpoint (POST /v1/sandbox/digest-blake2b512-base64-latin1) for testing. Use this paid endpoint when you need guaranteed production-grade hashing with a keyed BLAKE2b-512 algorithm and Base64 output in a single atomic call.
Side effects
- Text contains characters outside the Latin1 (ISO-8859-1) range — server may reject or misinterpret input
- Key exceeds 512 characters or is empty — schema validation error
- Text exceeds 100,000 characters — request rejected
- Payment of $0.007 USDC not provided or fails — 402 Payment Required returned
- Network timeout or service unavailability — connection 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. |
