Introduction

Learn how to integrate real-time stock market data into your app. The Stock API integration allows your app to access real-time and historical market data using Finnhub, a trusted financial data provider. With this integration, you can build features such as stock price tracking, portfolio dashboards, watchlists, and market insights directly inside your application. This integration makes it easy to incorporate financial data without needing to manually connect complex market data services.

​
What You Can Build

With the Stock API enabled, your app can support a variety of financial features including:
  • Real-Time Stock Quotes – Display live stock prices for companies listed on major exchanges.
  • Watchlists – Allow users to create and monitor a personalized list of stocks.
  • Portfolio Tracking – Track investments and automatically calculate the value of a user’s holdings.
  • Market Insights – Display price movements, daily changes, and other useful stock indicators.
  • Financial Dashboards – Build interactive dashboards that visualize market activity and portfolio performance.

​
How It Works

When the Stock API is enabled, your app can fetch financial data directly from Finnhub’s market data services. This allows your application to retrieve updated stock information including:
  • Current stock price
  • Daily gain or loss
  • Trading volume
  • Historical performance
  • Company market data
Your app can then use this information to power dynamic financial interfaces such as charts, tickers, or portfolio summaries. Because the integration handles the connection to Finnhub, you can focus on designing the experience and features inside your app.

​
Example Prompts

You can use prompts like these when building your app: Add a real-time stock ticker Add a real-time stock ticker to my app that shows prices for a user-selected watchlist using Finnhub. Add a portfolio tracker Add a portfolio tracker to my app that calculates each holding’s total value and daily gain or loss. These prompts allow you to quickly generate financial features inside your app.

  • Investment tracking apps
  • Finance dashboards
  • Trading companion tools
  • Personal portfolio managers
  • Market data widgets
Whether you’re building a simple price tracker or a full investment dashboard, this integration helps you bring real-time financial data into your app quickly.
