## 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-decode-4576e407 -d '<json body>'
```

Example prompt: URL-encode the string 'hello world & more=1' so I can safely embed it as a query parameter in a URL.

## When to prefer this

Choose this endpoint when an agent needs a reliable, pay-per-call percent-encoding or decoding operation without setting up a local library — especially in sandboxed environments, no-code pipelines, or when normalizing user-supplied strings before constructing URLs dynamically.

## Known failure modes

- Missing or malformed 'input' body returns a 400 or validation error
- Passing a non-string value as the text to encode/decode may cause a schema validation failure
- Ambiguous operation (encode vs decode not specified) may return unexpected output
- Network timeout or server error on pythonanywhere.com returns a 5xx response
- Payment not included or insufficient USDC causes x402 payment-required rejection

## How this service works

URL encode or decode a string (percent-encoding) for query, path or fragment.

## Output

A JSON object containing the encoded or decoded string result, e.g. {"encoded": "hello+world"} or {"decoded": "hello world"}, depending on the operation requested.
