Today we will talk about Market Data and Stock APIs. We’ll split this post into two sections:
1) What is an API?
2) Market Data and Stock APIs
Part 1: What is an API?
API, or application programming interface, basically describes one way to plug your website into another. Commercial sites make some parts of their code available to developers so that they can build tools for the site. The code they expose is called the API and the stuff they build, such as widgets, are called applications. Developers can use different APIs in different ways to build different things. For example, let’s look at KAYAK, a fare aggregator and travel metasearch engine which aggregates information from a number of different airline databases. The travel service interacts with an airline’s API. The API is the interface that can be asked to get information from the airline’s database to book seats, baggage options, etc. Then, the API takes the airline’s response to your request and sends it back to KAYAK, which then shows the updated and relevant information to its customers.
Part 2: Market Data and Stock APIs
Now that you have a basic understanding of how APIs work and what they can be used for, let’s talk about how APIs are useful in the world of stock trading. There are countless APIs offered for financial data. We’ll use Benzinga as an example because we offer over 60 financial data APIs on our website, https://cloud.benzinga.com/. Similar to how KAYAK interacts with airline’s APIs to obtain the relevant and updated information, Benzinga’s customers can purchase access to our APIs and use them on their website, platform or application to receive market data, news and other types of financial data. For example, say a customer wants to buy access to our Analyst Ratings API to use on their trading platform. Once purchased, our Analyst Ratings data is available to the customer through our API, which would then show up on their platform for their customers to see.
You may wonder, what are the different types of market data and stock APIs? Benzinga’s data catalogue lists industry-leading stock, market data, news and other types of financial APIs. Here’s a list of some popular financial APIs from our website:
