APIs come in many shapes and sizes, which can make it pretty difficult for newcomers to understand what they are and how they can be used. At Postman we enjoy working with APIs. Seriously. We do. We believe APIs can be used for fun and for business. To help illustrate how we see the world of APIs, we’ve crafted a new public collection of APIs that includes REST API examples for newbies to play with.

In order for people to learn about APIs, we want to make the experience interesting and hands-on—helping you to learn not just how APIs work, but also how the web works in general (83% of web traffic is API traffic, so if you know how APIs work, you know how the web works).

With so many differences in APIs, Postman reveals the underlying technical protocols when HTTP is used. We aim to clarify the nuances of working with RESTful APIs, GraphQL APIs, as well as the original format of SOAP, making Postman an ideal place to learn more about how all HTTP APIs work (and don’t work) with real-world API examples. Because REST APIs are the backbone of web, mobile, and device applications today, this collection is a valuable resource for learning about APIs that affect our daily lives.

Our intention behind Postman’s new public REST API collection is to help you keep growing and progressing in your career, and find more success working with SaaS and other software solutions that you depend on to get your job done.

Removing the friction of authorization with public APIs

Along with the many differences in APIs, the added layer of API authorization can keep even the most hardened developer away from APIs. Depending on the API, there could be upwards of 20 different authorization approaches potentially in use, dramatically increasing the difficulty of ever getting to make your first API call. With so much friction from the start, developers sometimes end up walking away.

Postman helps API providers and consumers ease the onboarding process; as part of this, we recommend getting rid of authorization altogether whenever possible. One of the reasons we crafted our public API collection is to help highlight that not all APIs need authorization. We offer authorization-free examples of APIs in the wild to simplify onboarding for new users.

Making APIs about what interests you

As noted above, learning about APIs can be challenging. That’s why this Postman public collection is made to reduce barriers to APIs and whet your appetite so that you can explore what APIs are all about. We want you to discover, play with, and find the value you’re looking for when it comes to putting API technology to work in your personal and professional world.

We had a lot of fun pulling together our new public API collection by test-driving hundreds of APIs to arrive at the 50+ we’ve aggregated in our new collection. You’ll find APIs about animals, bikes, comics, drones, gender, music, news, space, trivia, and numerous other topics. Hopefully, we landed on at least one that interests you.

Pulling back the curtain on the web

Postman is founded on the premise of helping developers pull back the digital curtain that exists around many of the abstract concepts powering the online world around us. Browsers and mobile phones give us a limited view of the web, but in reality there is so much more to the ever-expanding web. Behind the web, mobile, and device applications that have become ubiquitous in our lives, there is another side of the web that you can see using Postman.

Our intent with Postman’s new public collection, with its numerous REST API examples,  is to open up your eyes to this hidden layer. By playing around with the API examples in this collection, you’ll develop a better understanding of how the web actually works, while also gaining more control over how you use it every day in your personal and professional worlds.

If you haven’t already downloaded the Postman app, you can get it for free here. Once you’ve downloaded Postman, go to this Public REST APIs collection page, click on the Run in Postman button for our public API collection, and you’ll immediately start to see how the applications you use every day rely on APIs to power the capabilities you depend on.
