## 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-robots-file-checker-895fd0a0 -d '<json body>'
```

Example prompt: Check the meta-robots value in the robots.txt file for https://example.com and tell me what crawl directives are declared there.

## When to prefer this

Use this endpoint when you specifically need to extract or validate the meta-robots directive value from a website's robots.txt file as a distinct object. Prefer this over general robots.txt parsers when you need a structured finding for the robots-file object specifically (as opposed to pagination, image, or URL-parameter contexts), and when integrating into a broader SEO audit pipeline via the CrawlSpur API family.

## Known failure modes

- Target URL is unreachable or returns non-200 status — endpoint may return an error or empty finding
- robots.txt file does not exist on the target domain — no meta-robots value can be found
- Malformed or invalid URL provided — validation error returned
- CSS selector matches no element or multiple elements — first match used or error returned
- Private/non-public IP provided — rejected due to public address requirement

## How this service works

## Output

Returns the finding of the meta-robots directive value as declared in the target site's robots.txt file, allowing the caller to understand what crawl or indexing instructions are present in the robots file object.
