How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object with: whether the path is allowed for the given user-agent, the matched rule and group, the full robots.txt parse result (groups, rules count, crawl delays), all discovered sitemap URLs with their status, the robots.txt URL fetched, and the origin domain.
Example use cases
Pre-crawl compliance check for a scraper
“Before my scraper starts, check if a bot named 'DataBot' is allowed to access /products on shopify.com — I need to know the matched rule and whether there's a crawl delay.”
Sitemap discovery for SEO audit
“Find all the sitemap URLs listed in the robots.txt for nytimes.com so I can start indexing their content structure.”
Verify Googlebot access to a blog path
“Check if Googlebot is allowed to crawl /blog/private-posts on example.com and tell me which robots.txt rule applies.”

Endpoint
