## 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 crawlspur-crawl-delay-check-for-parameter-urls-6bf2d9c2 -d '<json body>'
```

Example prompt: Check the declared crawl delay for https://example.com/products?category=shoes&sort=price — I want to know what crawl delay is set for that parameterized URL.

## When to prefer this

Use this endpoint when you specifically need to check the declared crawl-delay directive for a URL that contains query parameters or URL parameters, as part of a technical SEO audit, crawl budget analysis, or indexing investigation. Prefer this over general robots.txt parsers when you need a per-URL, parameter-specific crawl delay check.

## Known failure modes

- Invalid or non-public URL returns validation error
- URL not reachable returns HTTP error or timeout
- No crawl delay directive found returns empty or null finding
- Malformed input schema returns 400-level error
- Domain does not have a robots.txt returns not-found finding
