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

An API (Application Programming Interface) allows you to send and receive data from a remote server, like querying a database. This is 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. For more detailed information on how APIs work, see here.

While most APIs require access via API keys (which are similar to passwords), or have complex methods of authentication, 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 access a sample data set for testing.

Big List of Free Open APIs

The APIs below can be accessed using any method:

  • your web browser (just click on the sample URLs to load them)
  • any modern coding language
  • cURL for the command line
  • no-code API clients like Swagger, Postman, or Insomnia
  • Mixed Analytics' own API Connector for Google Sheets

    • 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.

  2. 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!

  4. 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?

  5. 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.

  6. 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.

  7. 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!

  8. Hi Ana,
    Thank you for the list. I just wanted to know if there is any API that i can test for free which can send a zip file as a response. I am doing a POC and i need to confirm the zip file flow.

  9. Hi, Thank you for providing this list of APIs, it looks really good. I believe you should also include (www.ipstack.com), which offers geolocation API and global IP database services globally.

    • You can find these by searching for "identity verification api" but I don't know of any free or open APIs for this, as far as I can see they are all enterprise solutions.

      Reply
    • Ah, I see it now, thanks. Looks pretty useful, though this list only includes GET requests at the moment (so that they can be accessed via the browser).

      Reply
    • Thanks for your feedback, but I wasn't able to replicate the issue -- I just clicked the loripsum.net sample API URL and it worked for me in my browser. Can you please share how you accessed it?
