Its output:

```json

## Run it

From code, with a Fous API key in `FOUS_API_KEY`; the answer's `data` holds the output:

```bash
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"method":"radar.cloudflare.com/get_domain_rank","input":{"website":"https://google.com/search"}}'
```

From an AI agent connected to the Fous MCP server: its `run` with the same method and input. To connect one, give it `set up https://fous.com/SKILL.md`.

## 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.
