How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with ok and paid confirmation flags, along with the parsed or raw robots.txt content for the requested domain, including directives such as User-agent, Disallow, Allow, Sitemap, and Crawl-delay rules.
Example use cases
Pre-scrape crawl policy check
“Before I start scraping techcrunch.com, can you pull up their robots.txt so I know which paths I'm allowed to crawl and which are off-limits?”
SEO audit of crawl directives
“I'm doing an SEO audit — fetch the robots.txt for shopify.com so I can review their crawl rules and make sure no important pages are accidentally disallowed.”
Competitor bot access research
“Can you retrieve the robots.txt for amazon.com? I want to see which user agents they restrict and what sections of the site are blocked from crawlers.”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/web/robots-txt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-signup, pay-per-call fetch of a website's robots.txt for crawl policy inspection, SEO auditing, or pre-scrape compliance checking. It is ideal for AI agents operating autonomously without persistent API credentials, leveraging x402 USDC micropayments for frictionless access.
Side effects
- Domain not found or unreachable — returns error or empty robots.txt
- Schema parameter missing or malformed — may return validation error
- Target site returns non-standard robots.txt format — parsing may be incomplete
- Payment failure over x402 — 402 response blocking access
- Rate limiting or Cloudflare Worker timeout for slow-responding domains
