How this service works
Call when an agent needs a blake2b512 digest of latin1 bytes, encoded as base64url. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2b512-base64url-latin1 first.
Output
Returns a base64url-encoded BLAKE2b-512 cryptographic digest of the provided Latin-1 encoded input text, optionally keyed with the supplied key string.
Example use cases
Content integrity fingerprinting
“Hash the Latin-1 string 'Invoice #4821: Total $500.00' with BLAKE2b-512 using the key 'invoicekey' and return the base64url digest so I can verify it hasn't been tampered with.”
Keyed message authentication
“Generate a BLAKE2b-512 keyed digest of the Latin-1 text 'user:alice;role:admin;exp:1720000000' using key 'authsecret99', encoded as base64url — I need it for a token integrity check.”
Deterministic document fingerprint
“Give me the base64url-encoded BLAKE2b-512 digest of this Latin-1 document text: 'Contrat de vente numéro 7, signé le 1er juillet' with no key, so I can store a unique fingerprint for deduplication.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2b512-base64url-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a BLAKE2b-512 hash of Latin-1 text with base64url output encoding, especially when a keyed (MAC-style) digest is required. Prefer the free sandbox variant (/v1/sandbox/digest-blake2b512-base64url-latin1) for testing. Use this paid endpoint for production workloads where guaranteed availability matters.
Side effects
- Input text contains characters outside Latin-1 range — may cause encoding errors or unexpected results
- Key exceeds 512-character maximum — rejected with validation error
- Empty text or key fields — rejected due to minLength:1 constraint
- Payment not provided or insufficient — 402 Payment Required response
- Service unavailable — 5xx error with no digest returned
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. |
