Free APIs Open Source APIs Estimated reading: 13 minutes 1289 views Contributors Big List of Free and Open Public APIs (No Auth Needed)An API (Application Programming Interface) allows you to query a database and send and receive data from a remote server. When developing an app or pulling metrics for reporting, this allows you to focus on presenting information in a unique or useful way rather than developing the underlying data set. Most weather apps, for example, get their weather forecast data from a weather API rather than building their own weather stations. See this page for more information on how APIs work.While most APIs require access via API keys (similar to passwords) or have complex authentication methods, there are a number of APIs that have no requirements at all. This is especially helpful for beginners because it allows you to begin exploring different APIs right away. It is also useful for web developers who want to test with a sample data set.Big List of Free Open APIsThe APIs below can be accessed using any method:your web browser (just click on the sample URLs
