DeFi Yields

Find DeFi yield pools across 400+ protocols and 100+ chains (DefiLlama data): APY split into base and reward, 30-day mean APY, 7-day APY change, TVL, stablecoin flag, impermanent-loss risk. Filter by chain (e.g. 'Base', 'Ethereum'), project (e.g. 'aave'), token symbol (e.g. 'USDC'), stablecoin_only, min_tvl_usd (default 1,000,000); sort by 'apy' (default) or 'tvl'. Outliers (flagged by DefiLlama or above 500% APY) are excluded unless include_outliers is true.

  body: JSON.stringify({"chain":"Base","symbol":"USDC","stablecoin_only":true,"limit":5}),
});
const { data, payment } = await res.json();  // payment.transaction = on-chain receipt
