noun-faq FAQs

APIs (Application Programming interface), is a software intermediary that allows two applications to talk to each other. In the case of a typical Trading API, on one end would be an application of your market broker (ICICI Securities for example) and on the other end would be your code or application.

There are numerous ways a Trading API can help you better your trading experience in not just stock markets, but other markets like commodities or forex as well. Trading APIs allow you to get live market prices, execute orders in real time, and help manage your orders and positions. Built especially for market participants with technical knowledge looking for personalised trading experience using innovative logic, Trading APIs can help one build a complete investment and trading platform in no time.

The Breeze API is a powerful Indian stock market API through which you can fetch live/historical stock market data, real-time OHLC and Options Chain data, order status over Websockets, automate your trading strategies, monitor your portfolio in real-time, and most importantly, pay zero brokerage for all F&O trades placed via API.
