# SHA-512/224 Base32 Latin1 Digest

> SHA-512/224 Base32 Latin1 Digest is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-24).

Computes a SHA-512/224 cryptographic hash of latin1-encoded bytes and returns the result as a Base32-encoded string.

## Facts

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-512-224-base32-latin1-digest-164c96ca -d '<json body>'
```

Example prompt: Compute the SHA-512/224 hash of the latin1 text 'Hello, world!' and give me the result as a Base32-encoded digest.

## When to prefer this

Choose this endpoint when you specifically need a SHA-512/224 digest (a truncated variant of SHA-512) applied to latin1-encoded bytes with Base32 output encoding. It is appropriate when downstream systems expect Base32 format, when latin1 encoding is required for compatibility with legacy data, or when SHA-512/224 is mandated by a security or interoperability standard. If you only need a plain-text or UTF-8 input, or a different output encoding such as hex or base64, prefer the corresponding sibling endpoints on agentshelf.syntexa.ch.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected
- Key exceeds 512 characters or is empty — validation error
- Input text is empty — validation error
- Non-latin1 characters may produce unexpected results if encoding assumptions differ
- Payment of $0.001 USDC not provided — 402 Payment Required response
- Network timeout or service unavailability — 5xx error

## How this service works

Call when an agent needs a sha512-224 digest of latin1 bytes, encoded as base32. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base32-latin1 first.

## Output

Returns a Base32-encoded string representing the SHA-512/224 cryptographic digest of the provided text interpreted as latin1 bytes. The output is a deterministic, fixed-length hash suitable for integrity verification or fingerprinting.
