How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
Returns a JSON object containing the source URL, the raw text content of the robots.txt file, and the HTTP status code from the origin server (e.g. 200, 404).
Example use cases
Check if bots are blocked
“Fetch the robots.txt for https://openai.com and tell me if any user-agents are disallowed from crawling.”
SEO audit of crawl directives
“Retrieve the robots.txt from https://shopify.com so I can see what paths are blocked from search engines.”
Verify site before scraping
“Before I start scraping https://news.ycombinator.com, can you pull its robots.txt and let me know if scrapers are allowed?”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/robots?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve and inspect a domain's robots.txt file without setting up your own HTTP fetch infrastructure, and when you want pay-per-request pricing via USDC on Base (x402 protocol) rather than a subscription. Ideal for lightweight, occasional lookups in an AI agent workflow where managing HTTP clients or egress is undesirable.
Side effects
- Target URL returns non-200 status (404, 403, 500) — still returned with the status code in the response
- Malformed or missing URL query parameter — request may fail or return an error
- Origin server is unreachable or times out — proxy may return an error or timeout response
- No robots.txt exists at the domain — returns 404 status with empty or error body
