Big List of Free and Open Public APIs (No Auth Needed)

by

An API (Application Programming Interface) allows you to send requests to a remote data set, like querying a database. The response will then be delivered back to your own application in a standardized format. This is very helpful when you’re building an app or pulling metrics for reporting, because it means you can focus on presenting information in a unique or useful manner, rather than developing the underlying data set. For example, most weather apps get their weather forecast data from a weather API, rather than building weather stations themselves.

Of course, the fastest way to understand how APIs work is to try them out. While most APIs require access via API keys (which are similar to passwords), or have complex methods of authentication and authorization, there are also quite a few APIs with no requirements at all. This is especially useful for beginners, as it means you can start exploring different APIs right away. It is also useful for web developers looking to simply access a sample data set for their app.

The APIs below can be accessed using any method:

  • your web browser
  • cURL for the command line
  • API clients like Swagger and Postman
  • Mixed Analytics’ own API Connector for Google Sheets (nearly all of these APIs can be accessed from the Applications menu, just look for the green “unlocked” icons).

    • Hey Ryan, thank you for that! And that’s a really good tutorial. I’ve never seen that site before, just signed up now and am checking it out.

      • Thank you. It is a real cool site with over 5 million users. Maybe you can share some of your codes with us on this site 🙂

  4. Actually this is very nice !!!! I am searching for fun and free api’s for a long time, this is like a crystal clear of what I exactly need !!! keep it up man …..Good Work!!!!!

  9. Thank you, thank you, THANK YOU for this list.
    I often need an API for testing something simple. Surprisingly (or unsurprisingly) hard to find many that don’t need a registration+key.
    So thank you for this list. It is gold!

  12. thanks guys i love this page it helps me alot, please is there any api on reators without key? thanks for any positive reply.

  24. Hello

    This is great and useful thanks. However do you have any where I can use Key and Secret’s to test api connectivity with high security which is more common these days?

  26. I just briefly tested the “Jokes” API and it immediately presented a racist joke. I did this during a class. You should reconsider listing that as a resource.

  28. Ana, we develop mission-critical environmental conservation apps for NGOs. Using Appsheet. New to APIs. Need access to soil and ecoregion data. Soil data from SSURGO and ecoregion data from US EPA. Should be possible. Can you find SSURGO APIs?

    Reply

    • Hey Mark! I would just Google “SSURGO APIs” and see if any of the results look like what you’re looking for. I tried and see several results, but since I don’t have any background knowledge, I can’t really evaluate their quality or relevance.

  29. Thank you for the list!

    Just to raise it to your attention, the pixelencounter link actually is a duplicate link to the openFDA site from above. Just thought you might want to fix it at some point. Otherwise the list is great!
