Basic use-cases in dxFeed API are extremely easy to understand and implement, requiring only 15-20 lines of code for quote listener/printer application. dxFeed offers both test and production environments. The test environment allows developers to test their applications with the dxFeed APIs, to ensure their application is well-integrated with the platform. A restricted set of non-fee-liable exchange data is made available on the test environment. The production environment offers the ability for customers to test using live exchange data, for the purposes of performance and content quality assurance.
