Depends on what you're looking for specifically. There are a few open source APIs that are free, like Wikipedia or some government sites. Some companies that have an API have a free tier, with a small number of family uses (like 100 requests). Other APIs, like Spotify, are free always. They enable people to look up song metadata and build playlists (with user permission via oAuth2). Here is a giant list of public/free APIs: https://github.com/public-apis/public-apis Note: many APIs will require you to create an account and get an API key. This is to allow the provider to cut you off if you exceed their usage limitations. Best of luck and happy coding!

r/ChatGPTCoding on Reddit: Which APIs do you use for FREE - Best free options for CODING
June 6, 2025 -
Hi Guys,
let's grow this thread.
Here we should accumulate all good and recommend options and the thread should serve as a reliable source for getting surprising good FREE API Options shown.
I'll start!:
I recommend using the Openrouter API Key with the unlimited and not rate limited Deepseek/Deepseek R1 0528 - free model.
It's intelligent, strong reasoning and it's good at coding but sometimes it sucks a bit.
I Roocode there is a High Reasoning mode maybe it makes things better.
In Windsurf you can use SWE-1 for free which is a good and reliable option for tool use and coding but it misses something apart from the big guns.
In TRAE you can get nearly unlimited access to Claude 4 Sonnet and other Highend Models for just 3$ a month! Thats my option right now.
And... there is a tool which can import your OpenAI-Session Cookie and can work as a local reverse proxy to make the requests from your Plus Subscription work as API request in your Coding IDE ..thats sick right?

RooCode + Gemini Flash 2.5 doesn't really let me down much for coding. Usually takes just a bit more requests and every now and then needing to look up a module that's not working to find a working version (looking at you moviepy >.>). Orchestrator mode also doesn't work well with flash 2.5 from my tests. Although recently I've just been using it more so as a tool in automated scripts. It makes as a very powerful summarizing tool + report generator. Much more thorough reports than its older 2.0 flash model.

OpenAI and Google give you some free usage if you’re willing to share data with them You can use Github Copilot with Roo Code, even the free tier Google’s Jules is free Claude Code with a Pro sub is a steal OpenAI Codex is pretty good and now on Plus too

We’ll share what we learn so that our users and the broader community can build more human-positive AI systems.

Yes there are. Google allows you to use their Gemini AI API for free. https://aistudio.google.com *Edit 11/12/2025 Seems like the number of requests per day has gotten worse Ngl these days I just selfhost my own AI's bc well. yeah. If you have the resources I would recommend looking into selfhosting light AI models.
