# SHA3-384 Digest of Hex Bytes, Base32-Encoded

> SHA3-384 Digest of Hex Bytes, Base32-Encoded is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Computes the SHA3-384 cryptographic hash of raw 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 sha3-384-digest-of-hex-bytes-base32-encoded-a92dc52a -d '<json body>'
```

Example prompt: Can you compute the SHA3-384 hash of these hex bytes — '4a6f686e446f65' — and give me the result encoded as Base32?

## When to prefer this

Use this endpoint when you specifically need a SHA3-384 hash (not SHA2 or other SHA3 variants) of raw binary data supplied as hex bytes, with the output encoded as Base32 (not hex or Base64). Prefer this over the unpaid sandbox variant when operating in a production environment or when the sandbox endpoint is unavailable. Choose this over SHA3-256 or SHA3-512 when the consuming system requires exactly 384-bit digests.

## Known failure modes

- Invalid or non-hex input string causes a 400 bad request error
- Input exceeds 100,000 character limit resulting in rejection
- Missing required 'text' field returns a validation error
- Malformed JSON body causes a 400 parse error
- Payment not included or insufficient returns a 402 Payment Required response

## How this service works

Call when an agent needs a sha3-384 digest of hex bytes, encoded as base32. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-384-base32-rawhex first.

## Output

Returns a SHA3-384 cryptographic digest of the input hex bytes, encoded as a Base32 string. The output is a deterministic, fixed-length hash suitable for integrity verification and fingerprinting.
