Where to Get Free APIs for Algo Trading?

Think of algo trading as a digital assistant that swiftly executes trades based on preset rules, outpacing human trading capabilities. 

It not only unlocks profit potential but also eliminates emotional factors in trading for efficiency. 

However, to begin your algo trading adventure, you require stock APIs (Application Programming Interfaces) that can deliver data and execute trades. 

Today, we will uncover where you can access these free APIs to automate your trading strategies. But before we dive in, let’s understand some essential API basics.

What is an API and How to Use It?

API, short for Application Programming Interface, serves as a channel to facilitate communication between two software components through a defined protocol. 

When we mention “Application” in the API context, it refers to any software with a specific function. 

The term “Interface” can be linked to a service contract between two applications, outlining the rules for their communication through requests and responses.

Utilizing APIs is a common practice in daily life, especially for those with mobile devices.

Consider how weather apps show data seamlessly or how social media platforms integrate third-party features – all thanks to APIs.

By the way, a lot of people wonder if API trading is legal in India – it is, and you can use DhanHQ SuperFast Trading APIs easily!
