## 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 gpt-5-5-x402-query-parse-tool-b407d828
```

Example prompt: Can you parse the query string out of this URL for me: 'https://example.com/search?q=hello+world&lang=en&page=2'? I just need the individual query parameters extracted as key-value pairs.

## When to prefer this

Prefer this endpoint when you need a lightweight, pay-per-call URL query string parser with no subscription overhead, especially when integrating with x402 USDC micropayment workflows on Base and only occasional parsing is needed.

## Known failure modes

- Missing required 'input' field returns validation error
- URL exceeds 2048 character limit returns rejection
- query string exceeds 5000 character limit returns rejection
- Malformed or non-HTTP URL may return parsing error
- Insufficient USDC balance or x402 payment failure blocks the request

## How this service works

Parse a query string or URL into repeated query parameters and first-value maps without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.

## Output

A JSON object with ok=true, tool='queryParse', a summary of the parsed query string, and the extracted key-value parameters from the provided URL's query component.
