+// Zealous Swap (Kasplex) — Pools adapter for DefiLlama yield-server
+// Pulls per-pool TVL (USD) and APR directly from our public API.
+//
+// Endpoint used: https://kasplex.zealousswap.com/v1/pools
+// Notes:
+// - We use `apr` from our API as `apyBase` (already annualized %).
+// - If `apr` is missing, we fall back to fee APR from volume * feeRate.
+// - We include `apyReward` only if our API reports a positive `farmApr`.
+// - Only emit pools with `hasUSDValues === true` and tvl > 10000 to avoid noise.
