Use cases
- Giving LLM agents structured tool access to real-time crypto/Web3 data (prices, gas fees, balances, DeFi metrics).
- Adding general utilities to agents (weather, AQI, sunrise/sunset, domain/DNS/WHOIS, IP/network checks).
- Building MCP-enabled assistants that need a broad toolbox without managing many separate API vendors.
- Prototyping pay-per-call workflows where costs map directly to endpoint usage.
