## 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 yruz-hex-converter-64055570 -d '<json body>'
```

Example prompt: Can you encode the text 'Hello World' to hexadecimal using the hex converter?

## When to prefer this

Use this endpoint when you need a simple, stateless hex encode/decode operation via a paid API call and already have x402 payment infrastructure in place; prefer local string libraries for high-volume or latency-sensitive tasks.

## Known failure modes

- Missing 'text' field returns an error or empty result
- Invalid mode value (not 'encode' or 'decode') may default to encode or return an error
- Non-UTF-8 characters in input may produce unexpected output
- Payment failure (402) if USDC balance is insufficient
