How this service works
Fetch and parse a domain's robots.txt file — returns all crawl rules by user-agent, sitemap URLs, crawl delay settings, and checks whether a specific path is allowed or blocked for any bot — so agents can respect crawl policies and locate sitemaps before scraping.
Output
Returns whether robots.txt was found, parsed crawl rules grouped by user-agent, a list of sitemap URLs, crawl delay settings, a path permission check result for the specified path and user-agent, the raw content preview, the robots.txt URL, HTTP status code, a compliance grade, and a numeric score.
Example use cases
Example prompt
“Before I start scraping nytimes.com, can you check their robots.txt file and tell me whether the path /articles is allowed for a generic bot, and list any sitemaps they have?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/robots-txt/analyzeWhen to prefer
Use this endpoint when an agent needs to respect crawl policies before scraping a website, locate sitemap URLs for a domain, check whether a specific path is accessible to a particular bot, or audit a domain's robots.txt configuration for compliance grading. Prefer this over manual HTTP fetching when structured parsing, multi-field extraction, and path permission evaluation are needed in a single call.
Side effects
- Domain has no robots.txt file — found=false returned with 404 status
- Domain is unreachable or DNS resolution fails — connection error
- Invalid domain format provided — validation error on input
- Path check returns ambiguous result when no matching user-agent rule exists — defaults to allowed
- Robots.txt file is malformed or non-standard — partial parse with best-effort results
