Web Scraping API for Go
Call AlterLab's web scraping API from Go applications using the standard net/http package. The JSON REST API integrates cleanly with Go's type system — define request and response structs, unmarshal directly, and run concurrent scraping jobs with goroutines.
Quick Start
package main
import (
"bytes"
"encoding/json"
"fmt"
"net/http"
)
func main() {
payload, _ := json.Marshal(map[string]string{
"url": "https://example.com",
})
req, _ := http.NewRequest("POST",
"https://alterlab.io/api/v1/scrape",
bytes.NewBuffer(payload),
)
req.Header.Set("X-API-Key", "YOUR_API_KEY")
req.Header.Set("Content-Type", "application/json")
client := &http.Client{}
resp, _ := client.Do(req)
defer resp.Body.Close()
var result map[string]interface{}
json.NewDecoder(resp.Body).Decode(&result)
fmt.Println(result["content"])
