If you want higher rate limits, get a free Demo API key (no credit card) at https://www.coingecko.com/en/api/pricing and add to `.claude/skills/crypto-coingecko/.env`: ``` COINGECKO_API_KEY=your-demo-or-pro-key ``` The script auto-loads the .env if present. **Without a key**, it uses the public endpoint — which has lower rate limits but works fine for ad-hoc research. ## Subcommands The skill ships a single Python script `cg.py` with t
