# SHA-512/256 Digest of Hex Bytes Encoded as Base32

> SHA-512/256 Digest of Hex Bytes Encoded as Base32 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Computes a SHA-512/256 hash of raw hex-encoded bytes and returns the result 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 sha-512-256-digest-of-hex-bytes-encoded-as-base32-4c9a6b75 -d '<json body>'
```

Example prompt: Can you compute the SHA-512/256 hash of these raw hex bytes — 'deadbeef0102030405060708' — and give me the result as a Base32 string?

## When to prefer this

Choose this endpoint when you specifically need a SHA-512/256 digest of data represented as raw hex bytes, with the result encoded in Base32 — a niche but precise combination not commonly offered by generic hashing APIs. Prefer the unpaid sandbox POST /v1/sandbox/digest-sha512-256-base32-rawhex endpoint first to avoid charges during development or testing. Use this paid endpoint in production or when the sandbox is unavailable.

## Known failure modes

- Invalid hex input (odd-length or non-hex characters) causes a 400 error
- Input text or key exceeds maxLength limits (100000 or 512 chars respectively) causes rejection
- Missing required fields returns a 400 validation error
- Network timeout or service unavailability returns a 5xx error
- Payment failure or insufficient USDC balance prevents call from completing

## How this service works

Call when an agent needs a sha512-256 digest of hex bytes, encoded as base32. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-256-base32-rawhex first.

## Output

Returns a Base32-encoded string representing the SHA-512/256 digest of the input interpreted as raw hex bytes. The output is a deterministic, fixed-length cryptographic hash suitable for integrity verification, fingerprinting, or protocol use.
