## 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":"similarweb.com/get_website_traffic","input":{"website":"notion.so"}}'
```

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 many monthly visits does notion.so get, and what's its global rank right now?
- Pull the Similarweb overview for canva.com — bounce rate, pages per visit, and average visit duration.
- Which countries send the most traffic to duolingo.com? Also show whether visits went up or down last month.
- I'm sizing up a competitor: give me the traffic estimate, category rank, and traffic source breakdown for https://www.allbirds.com/collections/mens.
- Check Similarweb for figma.com's monthly traffic and its rank in the US.
