Bing Custom Search API

An easy-to-use, ad-free, commercial-grade search tool that lets you deliver the results you want.

Leverage Bing Custom Search to build a search that fits your needs with powerful ranking, a global-scale search index and document processing. Setup is easy and fast. The core technology works in three steps: it identifies on-topic sites, applies the Bing ranker and delivers relevant search results while allowing you to adjust the parameters at any time.

Customise your search

Quickly and reliably define the slices of the web that you want to draw from. Change the parameters of the sites you want and don't want at any time. Explore site suggestions to intelligently expand the scope of your search domain.

Easy-to-use

Custom Search features a straightforward UI that enables you to create your web search without a line of code.

Commercial-grade

Usage is ad-free – no matter how much or how little of the service you use.
