How this service works
robots.txt + llms.txt checker: crawler access verdicts for major search AND AI bots (Googlebot, Bingbot, GPTBot, ClaudeBot, PerplexityBot, CCBot, Google-Extended and more), declared sitemaps, syntax warnings, and llms.txt / llms-full.txt presence with structure summary. ?url=any page on the site
Output
Returns crawler access verdicts (allow/disallow) for major search bots (Googlebot, Bingbot) and AI bots (GPTBot, ClaudeBot, PerplexityBot, CCBot, Google-Extended, and more), a list of sitemaps declared in robots.txt, any syntax warnings found, and whether llms.txt and llms-full.txt are present along with a structural summary of their contents.
Example use cases
Audit competitor AI bot policies
“Pull up the robots.txt and llms.txt for anthropic.com — I want to see whether GPTBot, ClaudeBot, and PerplexityBot are allowed or blocked, what sitemaps they've declared, and if they have an llms.txt file set up.”
Check site before AI training crawl
“Before we start crawling nytimes.com for training data, check their robots.txt — I need to know if CCBot, GPTBot, and Google-Extended are allowed, any syntax warnings we should be aware of, and whether they have an llms.txt.”
Diagnose missing search engine traffic
“My site mybusiness.com has dropped out of Google and Bing search results — can you check the robots.txt to see if Googlebot or Bingbot are being blocked, flag any syntax errors, and tell me what sitemaps are declared?”
Technical details
Endpoint
GEThttps://api.webbersites.com/api/seo/robots-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to audit a website's crawler access policies in one call — specifically when you need verdicts for both traditional search bots AND AI training/inference bots simultaneously, and also want to check llms.txt presence. Prefer this over a generic HTTP fetch when you need structured, interpreted bot-by-bot verdicts rather than raw file content.
Side effects
- URL parameter missing — returns 400 error
- Unreachable domain or invalid URL — returns error or empty robots result
- robots.txt returns non-200 status — noted in response
- llms.txt absent — field returns null or absent indicator
- Malformed robots.txt — syntax warnings returned but parsing continues
