5 Free APIs I Actually Use Every Week (With Working Code)

There are thousands of free APIs. Most are toys. These 5 are the ones I actually use in production every single week. 1. Open-Meteo — Weather Without Signup curl "https://api.open-meteo.com/v1/forecast?latitude=52.52&longitude=13.41&current_weather=true" No API key. No signup. Global coverage. I use it in a CLI tool that checks weather before I go running. Full tutorial: Build a Weather CLI in 20 Lines of Python 2. Wikipedia REST API — Knowledge on Demand curl "https://en.wikipedia.org/api/rest_v1/page/summary/Python_(programming_language)" | jq '.extract' No key needed. 300+ languages. I use it to enrich content with background information. Full tutorial: Wikipedia API Guide 3.
