How to Scrape Amazon Bestsellers with TypeScript

Amazon Bestsellers contains valuable data — product title, ASIN, bestseller rank, category, 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 TypeScript and the Scavio API. By the end, you will have a working TypeScript script that fetches real-time Amazon Bestsellers data and parses the results.

Prerequisites

• TypeScript installed on your machine
• A Scavio API key (free tier includes 500 credits/month — no credit card required)

Step 1: Install Dependencies

Install fetch to make HTTP requests:

npm install typescript tsx

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 product title, ASIN, bestseller rank, and more.

const API_KEY = "your_scavio_api_key";

interface AmazonBestsellersResult {
  search_metadata: { status: string };
  organic_results: Array<{ position: number; title: string; link: string; snippet: string }>;
}

const response = await fetch("https://api.scavio.dev/api/v1/search", {
  method: "POST",
  headers: {
    "x-api-key": API_KEY,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ query }),
});

const data: AmazonBestsellersResult = await response.json();
for (const result of data.organic_results?.slice(0, 5) ?? []) {
  console.log(`${result.position}. ${result.title}`);
  console.log(`   ${result.link}\n`);
}

Step 3: Example Response

The API returns structured JSON. Here is an example response for a Amazon Bestsellers search:

{
  "search_metadata": { "status": "success" },
  "bestseller_results": [
    {
      "position": 1,
      "title": "Apple AirPods Pro (2nd Gen)",
      "asin": "B0BDHWDR12",
      "rank": 1,
      "category": "Electronics > Headphones",
      "price": "$199.00"
    }
  ]
}

Every field is structured and typed — no HTML parsing, no CSS selectors, no regex extraction. Your TypeScript code can access any field directly.

Step 4: Full Working Example

Here is a complete, runnable TypeScript script that searches Amazon Bestsellers and prints the results:

/**
 * Scrape Amazon Bestsellers search results with full type safety.
 * Run with: npx tsx amazon-bestsellers-search.ts
 */

const API_KEY = process.env.SCAVIO_API_KEY!;

interface AmazonBestsellersResult {
  search_metadata: { status: string };
  organic_results: Array<{ position: number; title: string; link: string; snippet: string }>;
}

async function searchAmazonBestsellers(query: string): Promise<AmazonBestsellersResult> {
  const response = await fetch("https://api.scavio.dev/api/v1/search", {
    method: "POST",
    headers: {
      "x-api-key": API_KEY,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({ query }),
  });

  if (!response.ok) {
    throw new Error(`Scavio API error: ${response.status}`);
  }

  return response.json();
}

const results = await searchAmazonBestsellers("electronics bestsellers");
console.log(JSON.stringify(results, null, 2));

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. 500 credits/month with no credit card required. Each search costs 1 credit.
