Here is a completely non-authoritative non-official not-necessarily-most-up-to-date-but-I-try list of Public API endpoints I have found over the years that are good for learning, experimenting, and testing… Most of them do not require you to sign up for an API Key. Some links go directly to the APIs for results, some go to their documentation. Feel free to drop me an email or tweet to let me know of some change I should make to the below. These things, being free for one and all, come and go faster than I notice so YMMV.
My MOST Valuable (Not Beginner) Testing APIs
These require particular request arguments or temporary signup. Beginners - go to the next section.
- POST Test: https://www.toptal.com/developers/postbin/
- POST/PUT/PATCH Test: https://dummyjson.com/ - Has an extensive schema of fake data
- MySQL Tests: https://www.db4free.net/ - Create a temporary SQL database (via signup)

Image Filler Libraries Galore
These APIs return images of various formats/sizes/specifications depending on the requests sent. They are constantly coming and going - (pour one out for fillmurray.com 😢) so, yaknow yaknow…
Generic Wireframe Filler Images
Useful, but not fun…you can specify sizes, colors, even text-content. It’s like a single call to return an image of a made up custom <div>…
- Dynamic Dummy Image Generator - https://dummyimage.com/
- DummyJSON’s Image placeholder - https://dummyjson.com/image/300
- Better Placeholder.com - https://betterplaceholder.com/
- Placeholder.com - Example: https://via.placeholder.com/200x200/aabbcc/010101/?text=Some+Custom+Text.png
- FakeImg.pl - https://fakeimg.pl/
- PlaceSkull - https://placeskull.com/ - notable specificallybecause it returns
.svgimage placeholders.
