How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object indicating whether the request is permitted (ok: true/false) based on the parsed robots.txt rules for the given site, path, and user-agent combination.
Example use cases
Pre-crawl permission check
“Before I start scraping https://techcrunch.com, check if the path /search is allowed for a user-agent called 'ResearchBot' according to their robots.txt.”
SEO audit robots blocking
“I'm doing an SEO audit — can you check if https://mystore.com has any robots.txt rule that blocks Googlebot from accessing /products?”
Automated scraper compliance
“I need to make sure my bot isn't violating robots.txt rules — check if user-agent '*' is allowed to crawl the path /api/data on https://opendata.gov.”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/robots_txt_check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or automation workflow needs to programmatically check crawl permissions before accessing a URL, ensuring compliance with a site's robots.txt without implementing a parser locally. Ideal for pre-scrape validation, SEO tooling, and ethical bot workflows. No API key required — pay per call via x402/USDC.
Side effects
- Site has no robots.txt (may default to allow-all or return an error)
- Unreachable domain causes timeout or connection error
- Invalid URL format returns a validation error
- Robots.txt has syntax issues that prevent reliable parsing
- Rate limiting or blocking by the target server
