# SHA-512 Base32 Digest of Hex Bytes (agentshelf.syntexa.ch)

> SHA-512 Base32 Digest of Hex Bytes (agentshelf.syntexa.ch) 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 a SHA-512 hash of raw hex-encoded bytes and returns the digest encoded as a Base32 string.

## 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-base32-digest-of-hex-bytes-agentshelf-syntexa-ch-b79aac9a -d '<json body>'
```

Example prompt: Compute the SHA-512 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 SHA-512 hash of raw hex-encoded bytes output in Base32 format — a niche but precise combination. Prefer the free sandbox variant (POST /v1/sandbox/digest-sha512-base32-rawhex) for testing. Use this paid endpoint when you need production reliability or the sandbox is unavailable. Do not use this for plain text hashing (use a text-input variant), for different hash algorithms (blake2b, blake2s, etc.), or for different output encodings (base64, hex).

## Known failure modes

- Invalid or non-hex input string causes a 400 error
- Input text or key exceeds maximum length limits (100,000 and 512 chars respectively) returns an error
- Malformed request body returns a 400 bad request
- Payment not provided or insufficient results in a 402 Payment Required response
- Server-side error returns a 500 response

## How this service works

Call when an agent needs a sha512 digest of hex bytes, encoded as base32. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha512-base32-rawhex first.

## Output

Returns a SHA-512 cryptographic digest of the input interpreted as raw hex bytes, encoded as a Base32 string. The output is a deterministic, fixed-length Base32 string suitable for use as a checksum, fingerprint, or content identifier.
