## 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 url-percent-encoder-6b7f9b39 -d '<json body>'
```

Example prompt: Can you percent-encode this string so I can safely put it in a URL: 'hello world & welcome to 2024!'?

## When to prefer this

Use this endpoint when you need server-side, reliable percent-encoding of a string and don't have access to a local encoding library, or when you want a consistent, standards-compliant result within an automated pipeline that already uses the x402render utility suite. Particularly handy when chaining with other endpoints on the same host (e.g. encode a value before embedding it in a JSON payload that is then minified).

## Known failure modes

- Missing or empty 'text' field returns an error
- Non-string input type may be rejected
- Payment failure (402) if USDC balance is insufficient or x402 payment header is missing

## How this service works
