Evaluating APIs from the catalog

Field	What to check
Auth	"No" = no registration needed
CORS	Matters for browser frontend, irrelevant for backend scripts
Limits	Most free APIs have daily caps — usually enough for personal tools

Weekend project ideas

News alerts: NewsAPI + keyword filter + Telegram bot (2-3 hours)
Sentiment signal: News feed + Hugging Face sentiment model + score -1 to +1
Weather dashboard: Open-Meteo + historical data + forecast for target city
Sports aggregator: Team form, injuries, home advantage in one view

Usage tip

For any new project needing external data: check this catalog first before assuming you need a paid API. Feed the full list to an agent and ask what's useful for the specific task — it will find connections you'd miss manually.
