The eBay Price Analytics API is a powerful tool for searching and retrieving product information from top eCommerce portals such as Amazon and eBay. With this API, developers can automate price comparison across multiple marketplaces and gain valuable insights into product pricing trends. The API offers a freemium subscription model with 100 API calls per month available for free under the BASIC plan. To get started, developers need to sign up for a RapidAPI developer account, navigate to the search page in the RapidAPI Console, subscribe to the Price Analytics API, and verify its operation by triggering a POST Create session request and then polling the results using a GET Poll session results endpoint. The API returns product listing data in JSON format, which can be extracted and visualized using tools like Plotly. By leveraging this API, developers can create interactive charts to compare prices across multiple marketplaces, enabling them to make informed decisions about product pricing and inventory management.
