POST/yields$0.003Top DeFi yield pools ranked by APY, with optional filters (chain, project, stablecoin-only, minimum TVL). Dust pools below `minTvlUsd` (default $10k) are excluded so reported APYs are meaningful.

POST/defi-overview$0.003DeFi market overview: total value locked (USD) across all chains, the chain count, and the top chains by TVL with each chain's TVL dominance. This is DeFi TVL — not total crypto market cap.
