How this service works
Fetch and parse a website's robots.txt. Returns rules per user-agent, sitemaps, crawl delays, and whether all crawlers are blocked.
Output

Example use cases
Validate competitor website crawling permissions
“I need to check if we're allowed to crawl our competitor's website. Can you pull their robots.txt and tell me what paths they're blocking and what their crawl delay requirements are?”
Audit third-party vendor compliance before integration
“Before we integrate with this new data vendor, can you check their robots.txt file and let me know if they block all crawlers or if there are specific rules we need to follow to respect their site?”
Discover sitemaps for SEO monitoring
“I'm setting up SEO monitoring for a client. Can you parse their robots.txt, pull out all the sitemaps they've listed, and tell me if Googlebot is allowed to crawl their site?”
