## 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-x-robots-tag-checker-for-pagination-bd32d1ef -d '<json body>'
```

Example prompt: Check what value the X-Robots-Tag header has on the paginated page at https://example.com/blog?page=2 — I want to know if it's set to noindex or something else.

## When to prefer this

Use this endpoint when you need to specifically validate the X-Robots-Tag HTTP response header on paginated pages (e.g. ?page=2, /page/3) as part of a technical SEO audit. Prefer this over generic HTTP header tools when you want structured SEO-domain findings with crawl directive semantics, or when checking pagination specifically as distinct from canonical tags or meta robots tags.

## Known failure modes

- URL is not publicly accessible — endpoint cannot fetch the target
- URL exceeds 2048 characters — input rejected
- Target server returns non-HTTP response — parsing fails
- No X-Robots-Tag header present — finding may return empty or null
- CSS selector matches zero elements — first filter match used or error returned
