# Blake2s-256 Digest — Base32/Latin1 Encoding

> Blake2s-256 Digest — Base32/Latin1 Encoding is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-29).

Computes a BLAKE2s-256 cryptographic digest of latin1-encoded input text and returns it as a Base32-encoded string.

## Facts

- Endpoint: POST https://agentshelf.syntexa.ch/v1/digest-blake2s256-base32-latin1?utm_source=zero.xyz
- Price: $0.005/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blake2s-256-digest-base32-latin1-encoding-fa6a7efe -d '<json body>'
```

Example prompt: Can you compute a BLAKE2s-256 hash of this latin1 text — 'Hello, world!' — and give me the result as a Base32 string? Use the key 'mySecretKey'.

## When to prefer this

Choose this endpoint when you specifically need a BLAKE2s-256 hash (not SHA-256, MD5, or other algorithms) with Base32 output encoding over latin1-interpreted text, particularly when you need deterministic, compact digests suitable for use in identifiers or integrity tokens. Prefer the free sandbox endpoint /v1/sandbox/digest-blake2s256-base32-latin1 when available.

## Known failure modes

- Text contains characters outside the latin1 range, causing encoding errors
- Key exceeds 512 character limit
- Text is empty or exceeds 100,000 character limit
- Payment of $0.005 USDC not received, returning 402

## How this service works

Call when an agent needs a blake2s256 digest of latin1 bytes, encoded as base32. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-blake2s256-base32-latin1 first.

## Output

Returns a Base32-encoded BLAKE2s-256 digest string computed over the latin1-interpreted input text, optionally keyed with the provided key parameter.
