# SHA3-224 Digest with Base32 Encoding and Latin-1 Input

> SHA3-224 Digest with Base32 Encoding and Latin-1 Input is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Computes a SHA3-224 cryptographic hash of Latin-1 encoded text 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 sha3-224-digest-with-base32-encoding-and-latin-1-input-7326166c -d '<json body>'
```

Example prompt: Hash the text 'Hello World' using SHA3-224, treating it as Latin-1 bytes, and give me the result encoded as Base32.

## When to prefer this

Choose this endpoint when you specifically need a SHA3-224 hash (not SHA-256, SHA3-256, or BLAKE2) with Base32 output encoding (not hex or Base64) and your input is Latin-1 encoded text. Prefer the free sandbox endpoint `/v1/sandbox/digest-sha3-224-base32-latin1` first; use this paid endpoint when the sandbox is unavailable or rate-limited. Use this over SHA3-256 or SHA3-512 variants when a 224-bit digest size is required.

## Known failure modes

- Text contains characters outside the Latin-1 range (U+0000–U+00FF), causing encoding errors
- Input text exceeds 100,000 character maximum length
- Key field exceeds 512 character maximum or is empty
- Payment of $0.005 USDC not provided or rejected via x402 protocol
- Service temporarily unavailable returning 5xx errors

## How this service works

Call when an agent needs a sha3-224 digest of latin1 bytes, encoded as base32. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base32-latin1 first.

## Output

Returns a Base32-encoded SHA3-224 digest string computed from the provided Latin-1 text input. The digest is deterministic and fixed-length (SHA3-224 produces a 224-bit output), encoded using the standard Base32 alphabet.
