## About real-time APIs
Get real-time data for currency, sporting events, transit systems, and more with real-time APIs.
## What is a real-time API?
A real-time application programming interface (API) is a service that enables users to automatically obtain information in real-time from one or more data resources. The API can be embedded in a software application or added to a website.
## How does a real-time API work?
APIs for real-time use Endpoint functionalities. Endpoints are the entryways to the service provided by the API vendor. Developers make GET requests through the endpoints to retrieve data described by the API.
## Who is a real-time API for?
An API that retrieves real-time information is for any developer who wants to build client applications to include live data retrieval functionality.
Businesses that frequently use live data as an integral part of their routine operations will also benefit from applications that contain APIs with real-time access capability.
## Why is a real-time data API important?
Developers can speed up their programming tasks with APIs that retrieve real-time data. This frees up their time to work on other projects sooner rather than later.
Applications with live data APIs can provide up-to-date information for businesses and consumers in certain sectors. For example, the travel industry, which caters to vacationing and outdoor activity planning, relies on APIs that provide current and forecasted weather information.
## What can you expect from real-time APIs?
Developers can count on building applications with real-time functionality without having to write or debug the code. They also will likely be able to create in-demand applications that help their clients achieve the results they need.
Businesses can stay competitive with the information they obtain with live data APIs. With APIs, they can expect to skip having to manually locate and harness fresh data from a variety of resources. The API does that for them.
## Are there examples of free APIs the access real-time data?
