Full profile of a web page in one paid call: <head> metadata (title, description, canonical, OpenGraph, favicon, feeds), DNS records (A/AAAA/MX/NS), robots.txt crawl permission for your user-agent, and domain registration/expiry (RDAP) — fanned out in parallel, each section with its own status. Pass ?userAgent= to test robots for a specific crawler. Page fetches are SSRF-checked. If every section fails technically you get a 503 and no charge.
