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 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 50 credits on signup -- no credit card required)
Step 1: Install Dependencies
Install fetch to make HTTP requests:
npm install -D typescript tsxStep 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.
const API_KEY = "sk_live_your_key";
const query = "electronics bestsellers";
interface AmazonBestsellersResponse {
data: { query: string; page: number; count: number; products: Array<{ asin: string; title: string; price: number; currency: string; rating: number; reviews_count: number; position: number; sales_volume: string | null }> };
response_time: number;
credits_used: number;
credits_remaining: number;
}
const response = await fetch("https://api.scavio.dev/api/v1/amazon/search", {
method: "POST",
headers: {
"Authorization": "Bearer " + API_KEY,
"Content-Type": "application/json",
},
body: JSON.stringify({ query, country: "us" }),
});
if (!response.ok) {
throw new Error("Scavio API error: " + response.status);
}
const data = (await response.json()) as AmazonBestsellersResponse;
const rows = data?.data?.products ?? [];
for (const row of rows.slice(0, 5)) {
console.log(row?.position);
console.log(" ", row?.title, row?.asin, row?.price, row?.rating);
}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 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:
/**
* Search Amazon Bestsellers data with the Scavio API.
* POST /api/v1/amazon/search - rows come back under data.products, 1 credit per call.
* Run with: npx tsx amazon-bestsellers.ts
*/
// 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.
const API_URL = "https://api.scavio.dev/api/v1/amazon/search";
const API_KEY = process.env.SCAVIO_API_KEY as string;
interface AmazonBestsellersResponse {
data: { query: string; page: number; count: number; products: Array<{ asin: string; title: string; price: number; currency: string; rating: number; reviews_count: number; position: number; sales_volume: string | null }> };
response_time: number;
credits_used: number;
credits_remaining: number;
}
async function searchAmazonBestsellers(query: string): Promise<AmazonBestsellersResponse> {
const response = await fetch(API_URL, {
method: "POST",
headers: {
"Authorization": "Bearer " + API_KEY,
"Content-Type": "application/json",
},
body: JSON.stringify({ query, country: "us" }),
});
if (!response.ok) {
throw new Error("Scavio API error: " + response.status);
}
return (await response.json()) as AmazonBestsellersResponse;
}
const data = await searchAmazonBestsellers("electronics bestsellers");
const rows = data?.data?.products ?? [];
for (const row of rows.slice(0, 5)) {
console.log(row?.position);
console.log(" ", row?.title, row?.asin, row?.price, row?.rating);
}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.
