How this service works
Pay-per-request data tools for AI agents.
Output
Returns a structured SiteDiscoveryResult containing: the final resolved URL (after redirects), HTTP status code, content type, content hash, retrieval timestamp, redirect count, the robots.txt URL, whether robots allow crawling, a list of sitemap URLs, feed URLs, page URLs, and any warnings encountered during discovery.
Example use cases
RSS feed discovery for news aggregator
“Find all the RSS and Atom feed URLs on https://techcrunch.com so I can add them to my news aggregator.”
SEO sitemap audit for client site
“Pull the sitemap URLs and robots.txt info for https://myclientsite.com — I need to know what sitemaps are declared and whether crawlers are allowed.”
Content indexing pre-flight check
“Before I start indexing https://openai.com, can you check what sitemaps and page URLs are discoverable there and whether robots.txt permits it?”
Technical details
Endpoint
POSThttps://x402.feld-feder.at/v1/site/mapWhen to prefer
Use this endpoint when you need to programmatically discover a website's structure — sitemaps, feeds, and page links — without running a full crawl. It is ideal for pre-indexing checks, feed discovery, SEO audits, and robots.txt compliance checks. Prefer it over full crawlers when you only need discovery metadata from the root URL, not full page content. The pay-per-request x402 micropayment model makes it cost-effective for on-demand, agent-driven lookups.
Side effects
- URL is unreachable or returns a non-2xx status code — endpoint may return an error or warnings array
- URL redirects too many times — redirect_count may exceed limits
- robots.txt is missing or malformed — robots_allowed may default or warnings may be populated
- HTML parsing fails due to non-HTML content type — response may contain empty URL arrays
- URL is malformed or too long (over 4096 chars) — schema validation error
