dxFeed JavaScript and REST API

For easy and seamless integration of market data with web-based projects dxFeed provides native JavaScript API essentially similar in form and function to the dxFeed Java API.

We run sample demo feed to try out our API with delayed data and limited subscription for testing the technology:
