Api Endpoint

data.japanagent.dev

Compare DeFi pool yields across chains with built-in risk screening. Filters by chain, asset and minimum TVL, and flags trap yields — unsustainable APY, reward-token dependence, low TVL, impermanent-loss and ML-predicted decline — so agents don't chase headline numbers into losses.
