To-do apps and calculators tell a recruiter you finished a tutorial. Real data tells them you can build products. Every project below uses only free APIs from this directory — most need no key at all.
Open-Meteo + its geocoder: search any city, show a 7-day forecast with animated icons. Deploy it; send the link, not a screenshot.
TVMaze (keyless) or TMDB: two random well-rated shows enter, one leaves. Add posters and ratings — it looks like a real product because it is one.
CoinPaprika prices + localStorage portfolio: give friends fake $10,000 and a leaderboard. Games get shared; shared projects get interviews.
REST Countries: flags, currencies, borders, maps — plus a quiz mode ("which country has this flag?").
TheMealDB: type the three ingredients in your fridge, get dinner. Real utility, real data, real photos.
PokeAPI is a rite of passage — do it properly: search, types, evolution chains, skeleton loaders.
Open Notify + a map: show the space station's live position and when it passes over your city.
Earthquakes (USGS), launches (Launch Library), headlines (Hacker News) — one page, three live feeds, pure "wow, real data".
Rule for all eight: deploy it live and link the repo. Our starter bundles group the APIs for each style of project.
