Rechercher sur le web

Firecrawl s’utilise avec Go via l’API REST. Utilisez net/http pour effectuer des requêtes directement. 
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, "échec de la requête : %v\n", err)
		os.Exit(1)
	}
	defer resp.Body.Close()

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

{
  "success": true,
  "data": {
    "web": [
      {
        "url": "https://docs.firecrawl.dev",
        "title": "Firecrawl Documentation",
        "markdown": "# Firecrawl\n\nFirecrawl is a web scraping API..."
      }
    ]
  }
}

​
Scraper une page

body, _ := json.Marshal(map[string]string{
	"url": "https://example.com",
})

req, _ := http.NewRequest("POST", "https://api.firecrawl.dev/v2/scrape", 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, "request failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

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

{
  "success": true,
  "data": {
    "markdown": "# Example Domain\n\nThis domain is for use in illustrative examples...",
    "metadata": {
      "title": "Example Domain",
      "sourceURL": "https://example.com"
    }
  }
}

​
Interact avec une page

Démarrez une session de navigateur, interactez avec la page à l’aide d’instructions en langage naturel, puis fermez la session.

​
Étape 1 — Scrapez pour démarrer une session

body, _ := json.Marshal(map[string]interface{}{
	"url":     "https://www.amazon.com",
	"formats": []string{"markdown"},
})

req, _ := http.NewRequest("POST", "https://api.firecrawl.dev/v2/scrape", 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, "request failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

var scrapeResult map[string]interface{}
json.NewDecoder(resp.Body).Decode(&scrapeResult)

data := scrapeResult["data"].(map[string]interface{})
metadata := data["metadata"].(map[string]interface{})
scrapeId := metadata["scrapeId"].(string)
fmt.Println("scrapeId:", scrapeId)

​
Étape 2 — Envoyer les interactions

// Rechercher un produit
interactBody, _ := json.Marshal(map[string]string{
	"prompt": "Search for iPhone 16 Pro Max",
})

interactURL := fmt.Sprintf("https://api.firecrawl.dev/v2/scrape/%s/interact", scrapeId)
req, _ = http.NewRequest("POST", interactURL, bytes.NewReader(interactBody))
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, "interact failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

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

// Cliquer sur le premier résultat
interactBody, _ = json.Marshal(map[string]string{
	"prompt": "Click on the first result and tell me the price",
})

req, _ = http.NewRequest("POST", interactURL, bytes.NewReader(interactBody))
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, "interact failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

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

​
Étape 3 — Mettre fin à la session

req, _ = http.NewRequest("DELETE", interactURL, nil)
req.Header.Set("Authorization", "Bearer "+apiKey)

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

fmt.Println("Session stopped")

Fonction utilitaire réutilisable

Pour des usages répétés, encapsulez l’API dans une petite fonction utilitaire : 
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})
}
Un SDK Go développé par la communauté est disponible pour l’API v1. Consultez la documentation du SDK Go pour en savoir plus.
