How this service works
Parse a site's robots.txt: whether a user-agent may crawl a path, which AI crawlers (GPTBot, ClaudeBot, Google-Extended, PerplexityBot, CCBot...) are blocked, and declared sitemaps. Check before your agent scrapes.
Output
A JSON object containing: the site URL, number of rule groups, a per-AI-bot status map (e.g. GPTBot: blocked/allowed) covering ~20 named bots, a query result showing whether a specific path is permitted for a given user-agent and which rule group applied, a list of sitemap URLs, and the raw robots.txt text.
Example use cases
Pre-scrape compliance check for agent
“I'm about to scrape techcrunch.com — can you check its robots.txt and tell me whether ClaudeBot is allowed and whether the path /startups is accessible?”
Audit which AI bots a site blocks
“I want to know which AI crawlers are blocked on openai.com — check GPTBot, ClaudeBot, PerplexityBot, Google-Extended and any others listed in their robots.txt.”
Find sitemaps for a content pipeline
“Pull the robots.txt for bbc.com and give me all the sitemap URLs it declares so I can feed them into my content indexer.”
Technical details
Endpoint
POSThttps://api.vextorium.com/robots-txt-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or scraper needs to check crawl permissions before accessing a site, audit how a site treats AI bots specifically, or discover sitemaps for content indexing. It is purpose-built for AI-bot-awareness (covering ~20 named AI crawlers) rather than being a generic SEO robots.txt tool.
Side effects
- Site has no robots.txt — empty or null result returned
- Domain does not resolve or is unreachable — fetch error
- Malformed robots.txt — parsing may produce incomplete group data
- Invalid URL input — API returns validation error
- Rate limiting or network timeout on the target site
