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.

Configure install-time cooldowns for npm/bun (minimum release age) and run a sandboxed pre-install scan when the cooldown has to be bypassed. Use when the user asks about supply-chain attacks, npm/bun security, "minimum release age", a "cooldown" for installs, hardening against Shai-Hulud-class worms, or how to safely install a package that was just published. Also use after any recent supply-chain incident in the npm ecosystem.
