# Spark Protocol API > Live protocol metrics for Spark (the Sky / former MakerDAO ecosystem capital-allocation protocol), keyless. Both Spark products: SparkLend, the lending money-market with per-asset supply APY and TVL, and Spark Savings, the sUSDS / USDS / USDC / USDT savings products passing through the Sky Savings Rate — a savings-yield dimension other lending APIs do not have. Plus total value locked and per-chain TVL. One combined overview endpoint snapshots it all. Live, nothing stored. The Spark-metrics layer for DeFi dashboards, lending, savings, stablecoin and yield apps — distinct from pure lending protocols, this is Spark lending-plus-savings model specifically. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
