Live apps from free APIs, no keys
€0+A dashboard with live weather, exchange rates and holidays, built only with free APIs. Then the prompts to build your own idea.
There is a public list of free APIs on GitHub called public-apis: weather, money, holidays, sports, food and more. About 498k people have starred it.
Many of them need no account and no key. That means Claude can build you a working app with live data in one go, without sign-ups or billing.
The folder has a working "morning dashboard" (weather, EUR→USD rate, next public holiday) and three prompts: make it yours, find the right APIs for your idea, and build it with Claude Code.
Take it free, or pay what you think it's worth. Same folder either way.
What's in the folder
A working dashboard
One HTML file: weather for your city, today's exchange rate, the next public holiday. Open it and it loads live data.
Find APIs for your idea
A prompt that searches the list, keeps only the no-key APIs, and tests each one before you build.
Build it with Claude Code
The build prompt, plus 3 ideas ready to take: invoice helper, holiday checker, on-site weather.
What you need
- Nothing to open the dashboard: just a browser.
- For the prompts: Claude (Claude Code is best, it can test the APIs for you).
