Stock Screener API From Intrinio For Free

We looked up the number of google searches for "Stock Screener API" and found out that only between 10-100 people search for it each month. Thats a tiny market, but if that is what you were looking for, you've come to the right place. This article explains what Intrinio's stock screener API is, how to get access for free, and provides example API calls.

What is the stock screener API?

The stock screener API is just that- it allows a fintech developer to sort through securities to find those that meet a set of predefined conditions. This is not a tool for financial analysts or non-developers. It is really easy to make the API calls but it requires a programming language to do more than copy and paste results.

The screener uses Intrinio's RESTful API to return a list of stocks that meet predefined conditions. The ticker and the value for each parameter are returned and can can be called in just about any language using curl or other packages native to that environment.

How to Get Access for Free?

Setting up an Intrinio account and getting API keys is free and easy. You can set up an account and copy your API username and API password at

After you set up an account you will notice that you are automatically subscribed to three of our free data feeds that include thousands of daily API calls to our Economic and US Fundamentals data.

This article explains how to get started with the API in general and includes examples of authenticating, sample code in numerous languages (Python, R, Ruby, C#, Node JS, Swift, PHP, etc), and sample API calls.

Why Use Intrinio?

Unlike big data providers, Intrinio doesn't bundle data feeds into an expensive monthly subscription. In fact, many of its feeds are free and others include redistribution at prices that are disruptively affordable.

Unlike smaller data providers, Intrinio only has one API. This means you can subscribe to the data feeds you need while still using a single API or Excel syntax rather than a different syntax for each provider.

This simplicity and cost structure is designed to make financial data easy to access and affordable for fintech developers and financial analysts. Thats our mission and the stock screener API is just another way we are increasing affordable access.
