# AgentShelf Base32Hex Encoder

> AgentShelf Base32Hex Encoder is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-02).

Encodes arbitrary text using the Base32Hex (extended hex) alphabet, returning the encoded string without any network or LLM calls.

## 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 agentshelf-base32hex-encoder-7a323120 -d '<json body>'
```

Example prompt: Can you base32hex-encode the text 'Hello, World! This is my test payload.' for me?

## When to prefer this

Choose this endpoint when you need a deterministic, offline base32hex encoding with no external dependencies — it performs no network calls and uses no LLM, making it fast and predictable. Prefer the free sandbox POST /v1/sandbox/base32hex-encode if available; use this paid endpoint when sandbox access is unavailable or you need production-grade reliability. It is distinct from standard Base32 (which uses A–Z2–7) and Crockford Base32.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment failure or insufficient USDC balance prevents the call from completing
- Malformed request body returns a 400-level error

## How this service works

Call when an agent needs text encoded with base32hex. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/base32hex-encode first.

## Output

Returns the base32hex-encoded representation of the submitted text string, using the extended hex alphabet (characters 0–9 and A–V), suitable for case-insensitive or DNS-safe contexts.
