The world runs on market data, and getting laggy, incomplete, or unreliable market data can cost you in more ways than one. In this blog, we’re covering what kinds of market data Intrinio provides, how to access it via the API, how much it costs, and more. 

What types of market data does Intrinio offer?   

Here’s a look at some of our most popular types of market data: 

  • Real-time snap and streaming equity prices
  • 15-minute delayed snap equity prices
  • Real-time and delayed US options prices
  • Historical intraday and EOD prices for stocks, ETFs, and options

What access methods are available for market data?   

Real-time, intraday, and EOD market data is available via our Web API. For real-time prices, you may also have the option to use our WebSocket API. Pulling prices via Web API makes sense for EOD prices or real-time prices if you don't need to update the data very often. If you want to stream a high volume of real-time prices, a WebSocket API will work better.  

We’ve provided extensive documentation to help you get started with the Intrinio API. You can also use our API Explorer to build the correct syntax for the API calls you need to make. 

We have SDKs in six popular programming languages that wrap around the Intrinio API. Currently, we offer SDKs for: 

Historical market data is available via bulk downloads with up to 50+ years of history. If you prefer using a database for your market data, you’re in luck – we recently integrated with Snowflake to provide powerful direct database access for our customers.

How do you access market data via API?

Our Web API is built by developers, for developers. This article offers a great introduction with links to documentation and other useful tools.  

The prices endpoint makes it easy to get multiple high/low/open/close (HLOC) datapoints in a single API call:

For US securities, you can just vary the ticker parameter and for international securities, you simply add the exchange. You can also get real-time stock prices via Web API:

If you are interested in pulling prices for a specific range of dates, the historical_data endpoint can be used as well as the prices endpoint:

The securities endpoint can be called with an optional parameter, last_crsp_adj_date, that returns a list of securities that have adjusted their stock prices due to a corporate event. This parameter is useful for configuring your application to only update historical prices if they have changed.
