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 Java and the Scavio API. By the end, you will have a working Java script that fetches real-time Amazon Bestsellers data and parses the results.
Prerequisites
- Java installed on your machine
- A Scavio API key (free tier includes 50 credits on signup -- no credit card required)
Step 1: Install Dependencies
HttpClient is built into Java, so there is nothing to install.
# HttpClient is built into Java 11+Step 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.
import java.net.URI;
import java.net.http.*;
var apiKey = "sk_live_your_key";
var query = "electronics bestsellers";
var body = "{\"query\":\"" + query + "\",\"country\":\"us\"}";
var request = HttpRequest.newBuilder()
.uri(URI.create("https://api.scavio.dev/api/v1/amazon/search"))
.header("Authorization", "Bearer " + apiKey)
.header("Content-Type", "application/json")
.POST(HttpRequest.BodyPublishers.ofString(body))
.build();
var client = HttpClient.newHttpClient();
var response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());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 Java code can access any field directly.
Step 4: Full Working Example
Here is a complete, runnable Java script that searches Amazon Bestsellers and prints the results:
import java.net.URI;
import java.net.http.*;
/**
* Search Amazon Bestsellers data with the Scavio API.
* POST /api/v1/amazon/search - rows come back under data.products. Requires Java 11+.
*/
// 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.
public class AmazonBestsellersExample {
private static final String API_URL = "https://api.scavio.dev/api/v1/amazon/search";
private static final String API_KEY = System.getenv("SCAVIO_API_KEY");
public static String searchAmazonBestsellers(String query) throws Exception {
var body = "{\"query\":\"" + query + "\",\"country\":\"us\"}";
var request = HttpRequest.newBuilder()
.uri(URI.create(API_URL))
.header("Authorization", "Bearer " + API_KEY)
.header("Content-Type", "application/json")
.POST(HttpRequest.BodyPublishers.ofString(body))
.build();
var response = HttpClient.newHttpClient()
.send(request, HttpResponse.BodyHandlers.ofString());
if (response.statusCode() != 200) {
throw new RuntimeException("Scavio API error: " + response.statusCode());
}
return response.body();
}
public static void main(String[] args) throws Exception {
System.out.println(searchAmazonBestsellers("electronics bestsellers"));
}
}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.
