r/learnprogramming on Reddit: Public API that doesn't require an api key?

May 22, 2025 -

I don't have access to a middleware or proxy server where I can store my key. I was wondering if there is a list of public APIs that don't require you to register and use a key. I would like to be able to make REST calls directly from my app.

What is your app doing and what do you want to make calls for? The entire premise of this question makes 0 sense at all. You wouldn't store an API key in middleware, thats not what that even is, and neither is a proxy server. I'm am so utterly confused by what you're trying to accomplish. What data are you trying to get into your app?
