## 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-sitemap-technical-indexability-check-8cd1fc5d -d '<json body>'
```

Example prompt: Can you check whether the sitemap at https://example.com/sitemap.xml is technically indexable — I want to know if there are any crawlability issues blocking search engines from indexing those URLs?

## When to prefer this

Use this endpoint when you need to specifically audit the technical indexability of a sitemap resource — as opposed to checking a regular page, news document, image, or robots.txt file. It is the right choice when diagnosing why a sitemap or its URLs may not be getting crawled or indexed by search engines, and when you need a precise, per-sitemap technical finding rather than a broad site audit.

## Known failure modes

- Sitemap URL is unreachable or returns non-200 HTTP status
- Provided URL does not resolve to a valid sitemap (e.g. returns HTML instead of XML)
- CSS selector matches zero or multiple elements when exactly one is required
- URL exceeds 2048 character limit
- Domain is private or behind a firewall and not publicly accessible
- Malformed input schema (missing required 'adresse' field in object form)
