Deep detail for a single reserve (rates, caps, risk parameters, utilisation, the interest-rate curve, token addresses) on v3 or v4. Every rate and percentage is a percent ('3.32' means 3.32%), named with a Pct suffix. On v4, utilisation and the rate curve are hub-wide, shared by every spoke drawing on the asset. Two v4 fields whose meaning the numbers do not give away: 'collateralFactorPct' is the liquidation boundary itself, because v4 has no separate liquidation threshold - do not look for one - so a position drawn to its full borrow limit sits at health factor 1.0; and 'liquidityFeePct' is the protocol's share of borrower interest, already netted out of supplyApyPct, so treating it as a user cost double-counts it (supplyApy = borrowApy x utilisation x (1 - liquidityFee), if you want to check). This is also where the asset's price lives: 'priceUsd', with 'priceSource' naming who priced it, and no listing carries either - get_markets quotes no price at all, so what an asset is worth on Aave is answered here. Use get_markets first to get the reserveId (v4) or market+token (v3).
