# SHA-256 Digest of Hex Bytes Encoded as Base32 (agentshelf.syntexa.ch)

> SHA-256 Digest of Hex Bytes Encoded as Base32 (agentshelf.syntexa.ch) 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 the SHA-256 hash of raw bytes provided as a hex string, then encodes the result 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-256-digest-of-hex-bytes-encoded-as-base32-agentshelf-syntexa-ch-cbc6b25c -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of these hex bytes — 'deadbeef0102030405' — and give me the result encoded as Base32?

## When to prefer this

Use this endpoint when you specifically need a SHA-256 hash of raw binary data (supplied as hex) with the result encoded in Base32 format — a niche but precise cryptographic combination. If a free sandbox version is available (POST /v1/sandbox/digest-sha256-base32-rawhex), prefer that first to avoid the $0.006 USDC charge. Choose this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Invalid or non-hex input string causes a validation error
- Empty input or input exceeding 100,000 character limit returns an error
- Malformed JSON body results in a 400 Bad Request
- Payment failure or insufficient USDC balance returns a 402 Payment Required

## How this service works

Call when an agent needs a sha256 digest of hex bytes, encoded as base32. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-base32-rawhex first.

## Output

Returns a Base32-encoded string representing the SHA-256 digest of the raw bytes provided as a hex-encoded input string.
