## 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-robots-txt-video-crawl-permission-check-964138b0 -d '<json body>'
```

Example prompt: Can you check whether the robots.txt file on this site allows crawlers to access this video URL: https://example.com/videos/my-product-demo.mp4?

## When to prefer this

Use this endpoint when you need to specifically verify robots.txt crawl permission for a video resource URL, as part of a technical SEO audit or before submitting video content to a sitemap. It is scoped specifically to video objects, making it more precise than a generic robots.txt checker for multimedia SEO workflows.

## Known failure modes

- Target URL unreachable or returns non-2xx HTTP status
- robots.txt file missing or inaccessible on the target domain
- Invalid or malformed URL submitted in the 'ziel' field
- URL exceeds maximum allowed length of 2048 characters
- User agent string fails pattern validation (must be alphanumeric/underscore/hyphen, 1-80 chars)
- Payment of $0.001 USDC not provided or rejected
