How this service works
Call when an agent needs a blake2s256 digest of text, encoded as base64. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-base64 first.
Output
Returns a base64-encoded BLAKE2s-256 cryptographic digest of the provided text. The result is a deterministic, fixed-length hash string computed entirely locally (no network calls or LLM inference involved).
Example use cases
Content integrity fingerprinting
“Hash the string 'user_session_token_abc123' with BLAKE2s-256 and give me the base64 digest so I can use it as a short integrity fingerprint.”
Keyed MAC generation for API payload
“I need a keyed BLAKE2s-256 digest of the text 'order_id=9921&amount=50.00' using the key 'mysecretkey' — return it as base64 so I can attach it as a message authentication code.”
Deterministic document identifier
“Generate a BLAKE2s-256 base64 hash of this document excerpt: 'The quick brown fox jumps over the lazy dog' — I want to use it as a stable, short document ID.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-blake2s256-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a compact, secure BLAKE2s-256 hash of text output as base64 specifically — ideal when downstream systems expect base64-encoded digests rather than hex or base32. Prefer the free sandbox variant (/v1/sandbox/digest-blake2s256-base64) for testing. Use this paid endpoint for production workloads where reliability and guaranteed processing matter.
Side effects
- Empty or missing text field returns validation error
- Key or text exceeding maximum length (512 and 100000 chars respectively) results in rejection
- Malformed request body returns 400-level error
- Payment failure or insufficient USDC balance returns 402 Payment Required
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. |
