How It Works

1. You ask a question in plain English
2. An AI agent selects the right on-chain data sources
3. Real-time data is fetched from the Bitcoin network
4. The agent synthesizes a structured analysis
5. Rich terminal output makes it screenshot-worthy

10 built-in data sources: fee estimates, fee recommendations, fee landscape analysis, mempool stats, mempool analysis, latest block, BTC price, mining stats, supply data, and network info.
