How this service works
Call when an agent needs a path checked against a site's robots.txt (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/robots-allowed first.
Output
Returns whether the specified path is allowed or disallowed for the given user agent based on the site's robots.txt, effectively indicating crawl permission status.
Example use cases
Pre-crawl compliance check for scraper
“I'm about to scrape https://shop.example.com/catalog — can you check if robots.txt allows access to /catalog for the user agent 'MyScraperBot/2.0' before I start?”
SEO audit: Googlebot access check
“Check whether Googlebot is allowed to access the path /admin on https://mysite.com according to their robots.txt rules.”
Verify bot policy before indexing
“I need to know if the robots.txt on https://news.example.com permits my crawler with user agent 'NewsAggregator/1.0' to fetch the path /archive/2023/.”
