There is also a website that provides 1400+ APIs in 30+ categories. It is named public apis and has 295k stars on GitHub.
This is a good list. But itโs worth adding a column that will display the free period; this is an important part for creating concepts and beginners.
Actually, everything was available on the website, including the categories list, free options, and other information, but I think it's not active anymore. (reason is the main issue linked on the repo)
There's nothing on the website.
This list is insane. You could build some really fun things with a lot of these. Thanks for such a great resource!
It is a gem for beginners who are looking for initial project ideas.
Great Resource to have in the bookmarks.
Really appreciate the work put into this blog!
Nice
Nice lists! Thanks!

Dude, amazing list. Thanks for sharing. Bookmarked.
Good list, but ahrefs API isn't free, they are only available to their paying customers (with no extra free)
Thank you. ahrefs isn't free
Thanks so much, the list is awesome. Bookmarked.
Pure gold!
