Everything You Need to Know About Stock Market APIs


The global stock market is both complex and volatile. Small changes can happen in mere milliseconds, but they can have huge financial consequences. Traders, hedge funds, and investors should therefore follow the stock market closely to make effective decisions.


Stocks APIs assist users in this task by providing relevant, accurate, and up-to-date stock market data, often in real-time. For this reason, stock APIs are increasingly being used in the financial industry.


What Are Stock Market APIs?


Exchange application programming interfaces (APIs) are programming interfaces that provide a wide variety of financial market data. Investors and traders use APIs to parse complex market data in a structured form, and developers can use APIs to enhance the functionality and richness of their digital tools.


Without APIs, traders are forced to collect and analyze raw data from multiple sources (exchanges, indices, news wires, etc.), all of which cannot be easily compared.


To manage the scale and complexity of market data, most brokerages rely on a variety of APIs to provide real-time and historical stock data to inform their trading decisions.


Stock market APIs differ from financial data websites such as Yahoo Finance or Google Finance, which only provide front-end access. In contrast, exchange APIs offer programmatic access that allows for more customizable use by the end-user.


Who Uses the Stock Market APIs?


Developers: Stock market APIs are a vital tool for anyone who develops software in the financial industry. They provide data that feed dashboards, data visualizations, and industry news apps, as well as trading algorithms that offer real-time trading recommendations.


Traders: Almost all tools used by traders – whether through a brokerage firm or any other online platform – are powered by exchange APIs. As a merchant, it's critical that the APIs that feed your platform is reliable and cover the data you need.


Why Should You Use the Stock Market APIs?


Generally speaking, there are two broad categories of people who would care about stock data APIs for different reasons.


Developers are often tasked with creating a tool for someone else to use. These:


  • A dashboard that visualizes exactly the stock items a company needs
  • A recommendation program that extracts actionable insights from financial data sets
  • A tool that automatically acts on available data, such as a trading algorithm


For all these purposes, developers will need to access exactly the right data provided by the trading APIs. It's easier to use a stock price API than to find a way to compile various data sources yourself.


Ask yourself how to choose a reliable stock market API


The stock API you choose will largely depend on your exact requirements. As such, finding the one that best suits your needs requires asking the following questions.


What is the data source?


Stock APIs differ in the types of data they provide and the data source itself. You'll want to choose a stock data API that gets the information you need from a legitimate and reliable source.


Are there any delays?


If your job involves snapshots, you'll want an API that has as little delay as possible in delivering live data to you. If speed is less critical, you can usually afford to work with a higher latency API.


What is the market coverage of APIs?


Decide whether you need data from a single exchange or details gathered from multiple sources. This will determine the market coverage of the API you choose.


What time zone does the API cover?


Some stock APIs provide live data to support real-time decisions. Others offer data with a few minutes delay. You can also find APIs that examine historical data to predict future trends. Note that real-time data tends to cost much more. So, choosing the stock API is a matter of balancing affordability with your corporate priorities.


How is the API priced?


As mentioned, real-time data often comes at a premium. However, API providers will also have different pricing models. Some will limit the number of data requests you can make in a time frame and charge you extra for additional requests.


You can find API providers with flexible pricing that lets you pay for required features as you go. Enterprise-grade providers can sell all-in-one packages with a long tie-in time. As always, your needs will dictate what you go for.
