Amazon Bestsellers contains valuable data -- products, badge, sales_volume, price, and more. Scraping this data directly means dealing with anti-bot detection, CAPTCHAs, IP rotation, and constantly breaking selectors. The Scavio API handles all of that and returns clean, structured JSON from a single POST request.
This tutorial shows you how to scrape Amazon Bestsellers using Go and the Scavio API. By the end, you will have a working Go script that fetches real-time Amazon Bestsellers data and parses the results.
Prerequisites
- Go installed on your machine
- A Scavio API key (free tier includes 50 credits on signup -- no credit card required)
Step 1: Install Dependencies
net/http is built into Go, so there is nothing to install.
# net/http is in Go's standard library - no installation neededStep 2: Make Your First Amazon Bestsellers Search
Send a POST request to the Scavio Amazon Bestsellers API endpoint with your query. The API returns structured JSON with products, badge, sales_volume, and more.
// There is no bestsellers endpoint and Amazon search takes no sort parameter, so this is
// the marketplace's default ranking for the query, not the Best Sellers chart. Store
// position per ASIN on each run to see movement.
package main
import (
"bytes"
"encoding/json"
"fmt"
"io"
"net/http"
)
func main() {
apiKey := "sk_live_your_key"
query := "electronics bestsellers"
body, _ := json.Marshal(map[string]interface{}{
"query": query,
"country": "us",
})
req, _ := http.NewRequest("POST", "https://api.scavio.dev/api/v1/amazon/search", bytes.NewBuffer(body))
req.Header.Set("Authorization", "Bearer "+apiKey)
req.Header.Set("Content-Type", "application/json")
resp, err := (&http.Client{}).Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()
raw, _ := io.ReadAll(resp.Body)
var data map[string]interface{}
json.Unmarshal(raw, &data)
formatted, _ := json.MarshalIndent(data, "", " ")
fmt.Println(string(formatted))
}Step 3: Example Response
The API returns structured JSON. Here is an example response for a Amazon Bestsellers search:
{
"data": {
"query": "electronics",
"page": 1,
"count": 16,
"products": [
{
"asin": "B0GRVFY42Q",
"title": "HP 15.6\" FHD Laptop 2026 Edition, Intel Processor, 8GB RAM",
"price": 414.99,
"currency": "USD",
"rating": 4.2,
"reviews_count": 517,
"position": 3,
"sales_volume": "2K+ bought in past month"
}
]
},
"response_time": 3160,
"credits_used": 1,
"credits_remaining": 4807
}Every field is structured and typed -- no HTML parsing, no CSS selectors, no regex extraction. Your Go code can access any field directly.
Step 4: Full Working Example
Here is a complete, runnable Go script that searches Amazon Bestsellers and prints the results:
// There is no bestsellers endpoint and Amazon search takes no sort parameter, so this is
// the marketplace's default ranking for the query, not the Best Sellers chart. Store
// position per ASIN on each run to see movement.
package main
import (
"bytes"
"encoding/json"
"fmt"
"io"
"net/http"
"os"
)
const apiURL = "https://api.scavio.dev/api/v1/amazon/search"
// SearchAmazonBestsellers calls POST /api/v1/amazon/search and returns the decoded response.
// Rows come back under data.products.
func SearchAmazonBestsellers(query string) (map[string]interface{}, error) {
apiKey := os.Getenv("SCAVIO_API_KEY")
body, err := json.Marshal(map[string]interface{}{
"query": query,
"country": "us",
})
if err != nil {
return nil, err
}
req, err := http.NewRequest("POST", apiURL, bytes.NewBuffer(body))
if err != nil {
return nil, err
}
req.Header.Set("Authorization", "Bearer "+apiKey)
req.Header.Set("Content-Type", "application/json")
resp, err := (&http.Client{}).Do(req)
if err != nil {
return nil, err
}
defer resp.Body.Close()
raw, err := io.ReadAll(resp.Body)
if err != nil {
return nil, err
}
if resp.StatusCode != http.StatusOK {
return nil, fmt.Errorf("scavio api error %d: %s", resp.StatusCode, string(raw))
}
var data map[string]interface{}
if err := json.Unmarshal(raw, &data); err != nil {
return nil, err
}
return data, nil
}
func main() {
data, err := SearchAmazonBestsellers("electronics bestsellers")
if err != nil {
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
}
formatted, _ := json.MarshalIndent(data, "", " ")
fmt.Println(string(formatted))
}Why Use Scavio Instead of Scraping Amazon Bestsellers Directly?
- No proxy management. Direct scraping requires rotating proxies to avoid IP bans. Scavio handles all of this server-side.
- No CAPTCHA solving. Amazon Bestsellers aggressively blocks automated requests. Scavio returns clean data every time.
- Structured JSON output. No HTML parsing or CSS selector maintenance. Get typed, consistent data from every request.
- Multi-platform in one API. Search Google, Amazon, YouTube, and Walmart from the same API key with the same authentication pattern.
- Free tier included. 50 credits on signup with no credit card required. Each search costs 1 credit.
