## 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-meta-robots-page-checker-2a551f14 -d '<json body>'
```

Example prompt: Check the meta-robots tag on https://example.com/blog/my-article and tell me what value it's set to — I need to know if it's noindex or something else.

## When to prefer this

Use this endpoint when you need to programmatically verify the meta-robots tag specifically on a standard page (seite) object — distinct from pagination, images, parameter URLs, or robots.txt files. Ideal for SEO audits, pre-launch checks, or diagnosing indexability issues on regular web pages.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status
- Page has no meta-robots tag, resulting in an empty or null finding
- Invalid URL format causes input validation failure
- CSS selector matches zero or multiple elements causing ambiguous results
- Page is behind authentication and inaccessible to the crawler
