How this service works

Quality-scored paid utility APIs for AI agents over x402 on Base USDC.

Output

Returns a JSON object with the resolved robots.txt URL, the HTTP status of the fetch, a list of crawl rule groups (each with user-agent and allow/disallow directives), and an array of sitemap URLs found in the file.

Example use cases

Pre-scrape crawl permission check

“Before I start scraping https://techcrunch.com, can you pull its robots.txt and tell me which paths are off-limits for automated bots and if there are any sitemaps I should use?”

SEO sitemap discovery

“I'm doing an SEO audit for https://shopify.com — can you inspect its robots.txt and pull out all the sitemap URLs listed in there?”

Competitor crawl policy research

“Can you check what crawl rules https://openai.com has set in its robots.txt? I want to know which user agents are restricted and what directories they can't access.”

Technical details

Endpoint

POSThttps://agent-utility-network.frosty-sound-4560.workers.dev/v1/paid/robots-inspect

When to prefer

Use this endpoint when an agent needs to programmatically check a site's robots.txt before crawling, scraping, or indexing — especially when you need parsed, structured output (groups and sitemaps) rather than raw text. Preferred over manual fetch+parse when you want instant structured data without building your own parser.

Side effects

URL is unreachable or returns a non-200 HTTP status — result will reflect the actual status code
robots.txt does not exist at the domain (404) — groups and sitemaps will be empty
Malformed URL input causes a validation error
The target server blocks the inspector's requests (e.g. firewall or rate limiting)
Very large robots.txt files may be truncated or time out
