Public APIs Developers Can Use in Their Projects
March 2, 2023 - These APIs offer a comprehensive array of weather information, including current temperature, wind speed, direction, humidity, atmospheric pressure, and precipitation. The only obstacle is that users must obtain a key. But they provide free or affordable access to their data for non-commercial use and small-scale projects.

Collection of free public APIs that No auth required.

The public-apis list is an awesome resource for developers. The only problem is that many of the APIs have become dead links over time. So I built a side project that takes that list and monitors API status daily, so you can see which ones are actually usable.

  • 860+ APIs that no auth required.

  • Reliability is monitored daily.

  • Test ednpoint directly in your browser.

r/AskProgramming on Reddit: What are some good, free REST APIs you all use?
April 29, 2024 -

The best free REST API I have come across is from the National Weather Service. I am, however, tired of playing with the weather. I am not looking for anything in specific, just something other than weather. I know there is https://www.data.gov , but there doesn't appear to be any good, up-to-date data available. It is entirely possible I am using those APIs incorrectly. So, please, would you mind passing along some good REST APIs for me to "play" with?

Thanks!

EDIT: I also use the APoD REST API, but that's getting a little old too.
