<div id="prerequisites">
  ## Pré-requisitos [#pré-requisitos]
</div>

* Wrangler CLI (`npm install -g wrangler`)
* Uma chave de API do Firecrawl — [obtenha uma grátis](https://www.firecrawl.dev/app/api-keys)

<div id="setup">
  ## Configuração [#configuração]
</div>

```bash
npm create cloudflare@latest my-scraper
cd my-scraper
npm install firecrawl
```

Adicione sua chave de API como um segredo:

```bash
wrangler secret put FIRECRAWL_API_KEY
```

<div id="search-the-web">
  ## Fazer uma busca na web [#fazer-uma-busca-na-web]
</div>

Crie um handler que pesquise na web e retorne resultados com o conteúdo completo da página.

Edite `src/index.ts`:

```typescript
import { Firecrawl } from "firecrawl";

export interface Env {
  FIRECRAWL_API_KEY: string;
}

export default {
  async fetch(request: Request, env: Env): Promise<Response> {
    const firecrawl = new Firecrawl({ apiKey: env.FIRECRAWL_API_KEY });
    const url = new URL(request.url);

    if (request.method === "POST" && url.pathname === "/search") {
      const { query } = (await request.json()) as { query: string };
      const results = await firecrawl.search(query, { limit: 5 });
      return Response.json(results);
    }

    return new Response("Not found", { status: 404 });
  },
};
```

<div id="scrape-a-page">
  ## Faça scraping de uma página [#faça-scraping-de-uma-página]
</div>

Adicione uma rota `/scrape` para extrair markdown limpo de qualquer URL.

```typescript
if (request.method === "POST" && url.pathname === "/scrape") {
  const { url: targetUrl } = (await request.json()) as { url: string };
  const result = await firecrawl.scrape(targetUrl);
  return Response.json(result);
}
```

<div id="interact-with-a-page">
  ## Interagir com uma página [#interagir-com-uma-página]
</div>

Adicione uma rota `/interact` para controlar uma sessão ativa do navegador — clicando em botões, preenchendo formulários e extraindo conteúdo dinâmico.

```typescript
if (request.method === "POST" && url.pathname === "/interact") {
  const result = await firecrawl.scrape("https://www.amazon.com", {
    formats: ["markdown"],
  });
  const scrapeId = result.metadata?.scrapeId;

  await firecrawl.interact(scrapeId, {
    prompt: "Search for iPhone 16 Pro Max",
  });
  const response = await firecrawl.interact(scrapeId, {
    prompt: "Click on the first result and tell me the price",
  });

  await firecrawl.stopInteraction(scrapeId);
  return Response.json({ output: response.output });
}
```

<div id="deploy">
  ## Deploy [#deploy]
</div>

```bash
wrangler deploy
```

<div id="test-it">
  ## Teste [#teste]
</div>

```bash
curl -X POST https://my-scraper.<your-subdomain>.workers.dev/search \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping"}'
```
