# WB Custom Search Engines

In order to return the most accurate results for E-commerce scraping, we divided the scraping scenarios into separate engines, called WB Custom Search Engines. When you want to scrape specific data from E-commerce websites, all you need to do is to set the appropriate **`engine=<WB_ENGINE>`** parameter when sending your request.

### Available WB Custom Engines

In this section of the WB Custom API documentation, we will cover all the available engines, along with their specific parameters and with detailed implementation examples for each search type:

* [wayfair\_async](/wb-custom-search-api/wb-custom-engines/wayfair-async-api.md) - scrape Wayfair product results
* [bestbuy\_async](/wb-custom-search-api/wb-custom-engines/bestbuy-async-api.md) - scrape Best Buy product results
* [nordstrom\_async](/wb-custom-search-api/wb-custom-engines/nordstrom-async-api.md) - scrape Nordstrom product results
