DeFi Yield Pools (filtered) ($0.008/call)

Every DefiLlama yield pool, filtered and sorted server-side so you don't fetch the 11MB index. Query: chain, project, symbol, min_tvl (USD), min_apy (%), stablecoin (true/false), sort (tvl|apy), limit (1-100). Each pool: project, chain, symbol, tvl_usd, apy, apy_base, apy_reward, stablecoin, il_risk, exposure. APYs move — poll it.

Paid endpoint: $0.008 per call via the x402 protocol (USDC on Base). An unpaid request returns 402 with payment requirements in the PAYMENT-REQUIRED response header; attach payment and retry.
