How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
Returns a JSON object containing the full robots.txt content as a string, the URL of the robots.txt file that was fetched, and the HTTP status code of the response (e.g. 200 if found, 404 if missing).
Example use cases
Pre-crawl permission check
“Before I start scraping https://shopify.com, can you check their robots.txt and tell me which paths are disallowed and whether they block any specific user-agents?”
SEO audit of competitor site
“I'm doing an SEO analysis — can you pull the robots.txt from https://competitor.com so I can see if they're blocking any important pages from indexing?”
Automated crawler policy enforcement
“My crawler is about to index https://techcrunch.com — first check their robots.txt and tell me whether general bots are allowed and which directories are off-limits.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/robots_check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically verify crawl permissions before scraping or indexing a website, especially in automated pipeline contexts where robots.txt compliance must be checked at scale. Prefer this over manual inspection or full-page scraping tools when you only need crawler directives rather than page content.
Side effects
- 404 status if the website has no robots.txt file
- Network timeout if the target domain is unreachable or slow
- Non-200 status if the domain blocks the fetching agent
- Malformed or empty robots.txt returned for unusual server configurations
- Invalid URL input causes schema validation error
