# SHA3-512 / Base32 / Latin-1 Digest

> SHA3-512 / Base32 / Latin-1 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Computes a SHA3-512 cryptographic hash of latin1-encoded text bytes and returns the digest encoded as a Base32 string.

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 sha3-512-base32-latin-1-digest-92cbae7f -d '<json body>'
```

Example prompt: Compute the SHA3-512 hash of the latin1 text 'Héllo wörld' and give me the result as a Base32-encoded digest.

## When to prefer this

Choose this endpoint when you specifically need a SHA3-512 hash of text interpreted as latin1 bytes with Base32 output encoding. Prefer the free sandbox endpoint (/v1/sandbox/digest-sha3-512-base32-latin1) for testing. Use this paid endpoint when the sandbox is unavailable or for production workloads. Choose alternative endpoints if you need a different hash algorithm (e.g. blake2s256), a different encoding (e.g. hex or base64), or a different input encoding (e.g. UTF-16LE or UTF-8).

## Known failure modes

- Input text contains characters outside the latin1 range (U+0000–U+00FF), causing encoding errors
- Missing or empty 'text' field returns a validation error
- Key field missing or invalid may result in authentication failure
- Text exceeding 100,000 characters is rejected
- Network timeout or service unavailability returns a non-200 response

## How this service works

Call when an agent needs a sha3-512 digest of latin1 bytes, encoded as base32. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-512-base32-latin1 first.

## Output

Returns a Base32-encoded SHA3-512 digest of the input text interpreted as latin1 bytes. The output is a deterministic, fixed-length Base32 string representing the cryptographic hash.
