USDC Base Yield API

How close USDC lending on Base is to the kink where borrow rates explode: per-protocol utilization, the kink read from the protocol's own rate curve, headroom in bps, and borrow APY at points around it. Aave and Compound only — Morpho's adaptive IRM has no static curve and DefiLlama-sourced protocols expose none, so they are marked unmeasured, never assumed stable. Describes state, not a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
