```elixir
config :firecrawl, api_key: System.get_env("FIRECRAWL_API_KEY")
```

<div id="search-the-web">
  ## 进行网页搜索 [#进行网页搜索]

end
```

<div id="scrape-a-page">

  url: "https://www.amazon.com",
  formats: ["markdown"]
)

scrape_id = get_in(scrape.body, ["data", "metadata", "scrapeId"])

# 使用 REST API 进行交互（基于 prompt）
headers = [
  {"Authorization", "Bearer #{Application.get_env(:firecrawl, :api_key)}"},
  {"Content-Type", "application/json"}
]

{:ok, _} = Req.post(
  "https://api.firecrawl.dev/v2/scrape/#{scrape_id}/interact",
  json: %{prompt: "Search for iPhone 16 Pro Max"},
  headers: headers
)

{:ok, response} = Req.post(
  "https://api.firecrawl.dev/v2/scrape/#{scrape_id}/interact",
  json: %{prompt: "Click on the first result and tell me the price"},
  headers: headers
)

IO.inspect(response.body)
