How this service works
Fetch robots.txt for a public site and report common AI crawler mentions plus the robots content.
Output
Returns the raw robots.txt content for the given domain, along with a structured report of which common AI crawlers (such as GPTBot, ClaudeBot, PerplexityBot, etc.) are explicitly mentioned, whether they are allowed or disallowed, and any relevant path-level directives.
Example use cases
Check if site blocks AI crawlers
“Pull up the robots.txt for nytimes.com and tell me if GPTBot or ClaudeBot are blocked from crawling it.”
Pre-scrape crawl policy check
“Before I scrape data from techcrunch.com, can you grab their robots.txt and tell me what paths are disallowed and if any AI bots are specifically called out?”
Audit own site's AI crawler policy
“Fetch the robots.txt for my site at myblog.com and report exactly what it says about AI crawlers — I want to know if I accidentally blocked any of them.”
Technical details
Endpoint
GEThttps://remarkable-creation-production-8797.up.railway.app/v1/robotsWhen to prefer
Use this endpoint when you need to programmatically check a site's robots.txt content and specifically want to see how AI crawlers are treated — it saves you from manually fetching and parsing robots.txt yourself. Prefer it over a generic HTTP fetch when you want structured AI-crawler mention extraction alongside the raw content. It pairs well with the sibling URL inspection and header-checking endpoints for a complete site audit.
Side effects
- Target URL is not publicly accessible or returns a non-200 status — robots.txt may not exist
- Malformed or missing 'target' query parameter returns a validation error
- Site returns a robots.txt that is very large or non-standard, which may produce incomplete parsing
- Private or localhost URLs may be rejected or fail to resolve
- Some sites serve robots.txt with incorrect content types, which may affect parsing accuracy
