Example use cases
Research DeFi protocol landscape
“Give me an overview of the DeFi protocols available — I want to know what lending, DEX, and yield protocols are out there so I can compare them.”
Identify top protocols by TVL
“Pull up the DeFi protocols data so I can see which ones have the highest total value locked and figure out where most liquidity is sitting.”
Build a DeFi dashboard data feed
“I'm building a DeFi dashboard — can you query the defi-protocols endpoint and return whatever protocol data it gives back so I can use it as a data source?”
