Use it from your agent

Give your agent this line. It reads SKILL.md, gets a Fous API key and connects the Fous MCP server. Its run then takes the method radar.cloudflare.com/get_domain_rank with the inputs above.

Ask your agent

  • How popular is notion.so globally? I'd like its popularity bucket and its exact rank if one is available.
  • Check Cloudflare Radar for where youtube.com ranks worldwide and show its weekly rank trend over recent weeks.
  • What categories does https://www.reddit.com/r/programming fall under, and what top-N bucket is it in?
  • Pull the worldwide traffic ranking for figma.com from Cloudflare, with a link to its Radar page.
  • Is duolingo.com in the top 1,000 or the top 10,000 sites on the internet? Include any recent rank history.
  • Lists recent and ongoing internet outages from Cloudflare Radar's Outage Center, optionally for one country. Countries and scope are null when the Outage Center does not identify them.

  • Gets the technologies shown in a website's free BuiltWith profile, grouped in the order BuiltWith displays them. A company name is matched to its official website through a public web search.

  • Checks a website's HTTPS setup with SSL Labs: overall grade, per-server grades, certificate issuer and expiry, supported protocols and known weaknesses. Reuses cached reports from the last 72 hours unless a fresh test is requested.

  • Looks up DNS records for a domain or pasted website link and summarizes its SPF record, DMARC policy and mail servers. A missing record type yields an empty records list.

  • Gets a company's Trustpilot rating summary from its name or website: TrustScore, rating label, total reviews, star breakdown, categories, claimed status, reply statistics and location when shown.

    trustpilot.com/get_company_rating
  • Checks whether an app or website has current problems in a country on Downdetector: its status, reports in the latest 15-minute interval, the usual report count, the most reported problem types and the most affected locations when shown. The service must have a public Downdetector page in that country.
