How to Scrape Amazon Bestsellers with cURL

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 cURL and the Scavio API. By the end, you will have a working cURL script that fetches real-time Amazon Bestsellers data and parses the results.

Prerequisites

• A terminal with cURL installed (pre-installed on macOS, Linux, and Windows 10+)
• A Scavio API key (free tier includes 50 credits on signup -- no credit card required)

Step 1: Install Dependencies

curl is built into cURL, so there is nothing to install.

# cURL is pre-installed on macOS, Linux, and Windows 10+

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.
curl -X POST "https://api.scavio.dev/api/v1/amazon/search" \
  -H "Authorization: Bearer sk_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"query":"electronics bestsellers","country":"us"}'

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 cURL code can access any field directly.

Step 4: Full Working Example

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

#!/bin/bash
# Search Amazon Bestsellers data with the Scavio API.
# POST /api/v1/amazon/search - rows come back under data.products.
# 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.

SCAVIO_API_KEY="${SCAVIO_API_KEY:-sk_live_your_key}"
INPUT="${1:-electronics bestsellers}"

curl -s -X POST "https://api.scavio.dev/api/v1/amazon/search" \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"query\":\"$INPUT\",\"country\":\"us\"}" | python3 -m json.tool

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.
