CoinGecko API Skill
Query the CoinGecko API for comprehensive crypto market data — prices, historical charts, exchange volumes, trending tokens, global stats, and category breakdowns. The free tier requires no API key and supports 30 calls/min.
When to Use This Skill
- Macro analysis: Global market cap, BTC dominance, total volume trends
- Historical data: Daily/hourly OHLCV going back years (not minutes-level)
- Cross-exchange comparisons: Exchange volume rankings and trust scores
- Trending/discovery: What tokens are trending on CoinGecko in the last 24h
- Category analysis: Compare DeFi vs L1 vs meme coin market caps
- Token research: Full metadata including links, description, community stats
Use Birdeye or DexScreener instead for real-time Solana DEX data, new token launches, or sub-daily granularity on Solana tokens.
