## 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-encode-utility-a08f5a6b -d '<json body>'
```

Example prompt: URL encode this string for me so I can safely use it as a query parameter: 'hello world & welcome=true'

## When to prefer this

Choose this endpoint when an AI agent needs a quick, reliable, micropayment-gated URL encoding operation as part of an automated pipeline — particularly when already integrated with the x402 payment protocol and needing a simple utility call without managing encoding libraries directly.

## Known failure modes

- Missing or null 'value' field may return an error or empty result
- Invalid options object may cause a 400 bad request
- Payment failure via x402 protocol will result in a 402 Payment Required response before the encoding is performed
- Network timeout on the hosted Render.com instance if service is cold-starting

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing the URL-encoded version of the input string in the 'result' field, along with the operation name 'url_encode' in the 'operation' field.
