  ## Prérequis [#prérequis]
</div>

* Elixir 1.14+ et OTP 25+

<div id="install-the-sdk">
  ## Installer le SDK [#installer-le-sdk]
</div>

Ajoutez `firecrawl` à votre `mix.exs` :

```elixir
defp deps do
  [
    {:firecrawl, "~> 1.0"}
  ]
end
```

Configurez votre clé API dans `config/config.exs` :

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

<div id="search-the-web">
  ## Rechercher sur le web [#rechercher-sur-le-web]
</div>

```elixir
{:ok, result} = Firecrawl.search_and_scrape(query: "firecrawl web scraping", limit: 5)

for entry <- result.body["data"]["web"] do
  IO.puts("#{entry["title"]} - #{entry["url"]}")
end
```

<div id="scrape-a-page">
  ## Scraping une page [#scraping-une-page]
</div>

```elixir
{:ok, result} = Firecrawl.scrape_and_extract_from_url(url: "https://example.com")
IO.puts(result.body["data"]["markdown"])
```

<Accordion title="Exemple de réponse">
  ```json
  {
    "success": true,
    "data": {
      "markdown": "# Example Domain\n\nThis domain is for use in illustrative examples...",
      "metadata": {
        "title": "Example Domain",
        "sourceURL": "https://example.com"
      }
    }
  }
  ```
</Accordion>

<div id="interact-with-a-page">
  ## Interact avec une page [#interact-avec-une-page]
</div>

Scrapez une page, puis continuez à l’utiliser via l’API de session de navigateur.

```elixir
{:ok, scrape} = Firecrawl.scrape_and_extract_from_url(
  url: "https://www.amazon.com",
  formats: ["markdown"]
)

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

# Utiliser l'API REST pour interact (basé sur des prompts)
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)

# Arrêter la session
Req.delete(
  "https://api.firecrawl.dev/v2/scrape/#{scrape_id}/interact",
  headers: headers
)
```

<div id="environment-variable">
  ## Variable d’environnement [#variable-denvironnement]
</div>

Définissez `FIRECRAWL_API_KEY` plutôt que de la coder en dur :

```bash
export FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```
