Query lending/borrowing rates, positions, and protocol data across major DeFi lending platforms.
Base: https://yields.llama.fi
All lending pools with APY:
web_fetch url="https://yields.llama.fi/pools"
Returns ~10k+ pools. Filter client-side by
projectandchain. Key fields:apy(supply APY),apyBorrow(borrow APY),tvlUsd,pool(unique ID)
Single pool detail + history:
web_fetch url="https://yields.llama.fi/chart/POOL_ID"
Filter tips: Search response for "project":"aave-v3", "project":"compound-v3", "project":"morpho", "project":"spark".
Get all reserves with rates:
exec command="curl -s -X POST 'https://api.thegraph.com/subgraphs/name/aave/protocol-v3' -H 'Content-Type: application/json' -d '{\"query\":\"{reserves(first:100){name symbol underlyingAsset liquidityRate variableBorrowRate stableBorrowRate availableLiquidity totalCurrentVariableDebt totalDeposits reserveFactor baseLTVasCollateral reserveLiquidationThreshold}}\"}"
Rates are in RAY (27 decimals). Convert:
rate / 1e27 * 100= APY%
User positions on Aave:
exec command="curl -s -X POST 'https://api.thegraph.com/subgraphs/name/aave/protocol-v3' -H 'Content-Type: application/json' -d '{\"query\":\"{userReserves(where:{user:\\\"0xUSER_ADDRESS_LOWERCASE\\\"}){reserve{symbol}currentATokenBalance currentVariableDebt currentStableDebt}}\"}"
