# Go

> Comece a usar o Firecrawl em Go. Faça scraping, realize buscas e interaja com dados da web usando a API REST.

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

* Go 1.21+
* Uma chave de API do Firecrawl — [obtenha uma grátis](https://www.firecrawl.dev/app/api-keys)

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

Firecrawl funciona com Go por meio da API REST. Use `net/http` para fazer requisições diretamente.

```go theme={null}
package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"os"
)

func main() {
	apiKey := os.Getenv("FIRECRAWL_API_KEY")

	body, _ := json.Marshal(map[string]interface{}{
		"query": "firecrawl web scraping",
		"limit": 5,
	})

	req, _ := http.NewRequest("POST", "https://api.firecrawl.dev/v2/search", bytes.NewReader(body))
	req.Header.Set("Authorization", "Bearer "+apiKey)
	req.Header.Set("Content-Type", "application/json")

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		fmt.Fprintf(os.Stderr, "requisição falhou: %v\n", err)
		os.Exit(1)
	}
	defer resp.Body.Close()

	result, _ := io.ReadAll(resp.Body)
	fmt.Println(string(result))
}
```

<div id="interact-with-a-page">
  ## Interaja com uma página
</div>

Inicie uma sessão no navegador, interaja com a página usando prompts em linguagem natural e, em seguida, encerre a sessão.

<div id="step-1-scrape-to-start-a-session">
  ### Etapa 1 — Faça o scraping para iniciar uma sessão
</div>

```go theme={null}
body, _ := json.Marshal(map[string]interface{}{

fmt.Println("scrapeId:", scrapeId)
```

  ### Etapa 2 — Enviar interações

```go theme={null}
// Buscar um produto

<div id="reusable-helper">
  ## Helper reutilizável
</div>

Para reutilizar, encapsule a API em um pequeno helper:

```go theme={null}
type FirecrawlClient struct {
	APIKey  string
	BaseURL string
	Client  *http.Client
}

func NewFirecrawlClient(apiKey string) *FirecrawlClient {
	return &FirecrawlClient{
		APIKey:  apiKey,
		BaseURL: "https://api.firecrawl.dev/v2",
		Client:  &http.Client{},
	}
}

func (fc *FirecrawlClient) post(endpoint string, payload interface{}) ([]byte, error) {
	body, err := json.Marshal(payload)
	if err != nil {
		return nil, err
	}

	req, err := http.NewRequest("POST", fc.BaseURL+endpoint, bytes.NewReader(body))
	if err != nil {
		return nil, err
	}
	req.Header.Set("Authorization", "Bearer "+fc.APIKey)
	req.Header.Set("Content-Type", "application/json")

	resp, err := fc.Client.Do(req)
	if err != nil {
		return nil, err
	}
	defer resp.Body.Close()

	return io.ReadAll(resp.Body)
}

func (fc *FirecrawlClient) Scrape(url string) ([]byte, error) {
	return fc.post("/scrape", map[string]string{"url": url})
}

func (fc *FirecrawlClient) Search(query string, limit int) ([]byte, error) {
	return fc.post("/search", map[string]interface{}{"query": query, "limit": limit})
}
```

<Note>
  Há um [SDK Go da comunidade](https://github.com/mendableai/firecrawl-go) disponível para a API v1. Consulte a [documentação do SDK Go](/pt-BR/sdks/go) para mais detalhes.
