How this service works
Call when an agent needs a blake2s256 digest of latin1 bytes, encoded as base64. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-base64-latin1 first.
Output
A Base64-encoded string representing the BLAKE2s-256 digest of the provided Latin-1 text, optionally computed with a secret key for keyed hashing (MAC).
Example use cases
Content integrity fingerprinting
“Hash the Latin-1 string 'Invoice #4821: $500.00 due 2024-06-01' with the key 'invoicekey' using BLAKE2s-256 and return it as Base64 so I can verify the content hasn't changed.”
Keyed message authentication
“I need a BLAKE2s-256 keyed digest of the message 'user:admin;role:superuser' with secret key 'authsecret99' encoded as base64 — this is for verifying API request authenticity.”
Deterministic token generation
“Generate a BLAKE2s-256 base64 digest of the Latin-1 text 'session:abc123:2024-06-01T00:00:00Z' with no key, so I can use it as a short deterministic session token.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-base64-latin1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, lightweight BLAKE2s-256 cryptographic digest specifically of Latin-1-encoded text with the output in Base64 format, and do not have access to local cryptographic libraries. It is also suitable for keyed BLAKE2s hashing (MAC) when a secret key is required. Prefer the unpaid sandbox endpoint /v1/sandbox/digest-blake2s256-base64-latin1 for development/testing to avoid the $0.009 USDC per-call cost.
Side effects
- Text contains characters outside Latin-1 range (only bytes 0x00–0xFF supported)
- Key exceeds 512-character limit or is empty when provided
- Text is empty or missing (minLength:1 required)
- Network timeout or upstream service error (HTTP 5xx)
- Payment failure — x402 payment protocol error or insufficient USDC balance
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. |
