# SHA-512 / Base32 / Latin-1 Digest

> SHA-512 / Base32 / Latin-1 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-02).

Computes a SHA-512 hash of latin1-encoded input text and returns it 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 sha-512-base32-latin-1-digest-243c6516 -d '<json body>'
```

Example prompt: Can you compute the SHA-512 hash of the text 'Hello, world!' treating it as latin1 bytes, and give me the result encoded as Base32?

## When to prefer this

Choose this endpoint when you specifically need a SHA-512 digest of latin1-encoded bytes output as Base32 (not hex or base64). Use the free sandbox endpoint POST /v1/sandbox/digest-sha512-base32-latin1 first for testing. Prefer this over generic hashing libraries when you need a hosted, API-accessible computation with no local dependencies. Use instead of the blake2s256-base64 sibling when SHA-512 is required by your protocol or verification partner.

## Known failure modes

- Input text exceeds 100,000 character limit — request rejected
- Key field missing or empty — validation error
- Text contains characters outside latin1 range that cannot be encoded — may produce unexpected results
- Payment of $0.009 USDC not provided or invalid — 402 Payment Required
- Service temporarily unavailable — 5xx error

## How this service works

Call when an agent needs a sha512 digest of latin1 bytes, encoded as base32. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-base32-latin1 first.

## Output

Returns a Base32-encoded SHA-512 digest of the provided text, treated as latin1 bytes. The response is a deterministic, fixed-length Base32 string representing the cryptographic hash of the input.
