# SHA-512/224 Digest with Base32 Encoding (Raw Hex Input)

> SHA-512/224 Digest with Base32 Encoding (Raw Hex Input) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Computes a SHA-512/224 cryptographic hash of hex-encoded bytes and returns the digest encoded as base32

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-digest-with-base32-encoding-raw-hex-input-761bf00d -d '<json body>'
```

Example prompt: Compute a SHA-512/224 hash of the hex bytes '48656c6c6f' and give me the result encoded as base32.

## When to prefer this

Choose this endpoint when you specifically need a SHA-512/224 digest (not SHA-256 or SHA-512) of binary data provided as raw hex, and require the output in base32 encoding rather than hex or base64. Prefer the free sandbox variant (/v1/sandbox/digest-sha512-224-base32-rawhex) when available. Use this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Invalid hex string input (non-hex characters) may cause a 400 error
- Empty or missing text/key fields return a validation error
- Input exceeding 100,000 character limit rejected
- Payment failure (x402) if USDC balance is insufficient
- Malformed request body returns 422 or 400 status

## How this service works

Call when an agent needs a sha512-224 digest of hex bytes, encoded as base32. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-224-base32-rawhex first.

## Output

A base32-encoded string representing the SHA-512/224 cryptographic digest of the provided hex-encoded input bytes. The response is deterministic — identical inputs always yield the same output.
