# SHA3-224 Base32 Digest of Raw Hex Bytes

> SHA3-224 Base32 Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-02).

Computes a SHA3-224 hash of raw hex-encoded bytes and returns the result 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-base32-digest-of-raw-hex-bytes-b8ae9d21 -d '<json body>'
```

Example prompt: Can you compute the SHA3-224 hash of these raw hex bytes — 'deadbeef0102' — and give me the result encoded as Base32?

## When to prefer this

Choose this endpoint when you specifically need a SHA3-224 digest (not SHA-256 or SHA3-256) with Base32 output encoding, and your input is already represented as hex bytes. Prefer the free sandbox POST /v1/sandbox/digest-sha3-224-base32-rawhex first if available; use this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Invalid hex string (odd length, non-hex characters) causes a 400 error
- Empty or missing text field returns a validation error
- Input exceeding 100,000 character limit is rejected
- Malformed JSON body results in a parse error
- Payment not attached or insufficient USDC triggers a 402 Payment Required response

## How this service works

Call when an agent needs a sha3-224 digest of hex bytes, encoded as base32. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-224-base32-rawhex first.

## Output

Returns a Base32-encoded SHA3-224 digest string computed from the input interpreted as raw hex bytes. No network calls are made; the computation is purely local and deterministic.
