# SHA3-256 + Base32 Digest of Raw Hex Bytes

> SHA3-256 + Base32 Digest of Raw Hex Bytes is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-25).

Computes a SHA3-256 hash of raw hex-encoded bytes and returns the digest encoded as Base32

## 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 sha3-256-base32-digest-of-raw-hex-bytes-818e493d -d '<json body>'
```

Example prompt: Can you compute the SHA3-256 hash of these raw hex bytes — '4a6f686e446f65' — and give me the result encoded as Base32?

## When to prefer this

Choose this endpoint when you specifically need a SHA3-256 digest of data provided as raw hex bytes, with the result encoded in Base32 (not hex or Base64). It is ideal when your downstream system expects Base32-encoded SHA3 hashes, or when you need a compact, case-insensitive representation of the digest. If you do not need Base32 output or SHA3-256 specifically, consider alternative hashing endpoints.

## Known failure modes

- Invalid or non-hex input string causes a parsing error
- Input exceeds maximum length of 100,000 characters
- Missing required fields returns a validation error
- Odd-length hex string may fail raw byte interpretation
- Payment not included or incorrect amount results in 402 response

## How this service works

Call when an agent needs a sha3-256 digest of hex bytes, encoded as base32. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/digest-sha3-256-base32-rawhex first.

## Output

Returns a Base32-encoded string representing the SHA3-256 digest of the input data interpreted as raw hex bytes. The response is a compact, uppercase Base32 string suitable for use as a checksum, identifier, or verifiable hash.
