# CSE

The Cse Service is the endpoint that returns the requested searches. You must identify a particular search engine to use in your request (using the cx query parameter) as well as the search query (using the q query parameter). In addition, you should provide a developer key (using the key query parameter). All other [query parameters](https://developers.google.com/custom-search/v1/using_rest#query-params) are optional.
