ApiToll DeFi Yields.

GET https://crypto.apitoll.cloud/v1/crypto/yields ↗

Highest-yield DeFi pools across every chain and protocol, filterable by chain, project, or asset symbol: each pool returns TVL in USD, total APY with base/reward split, stablecoin flag, impermanent-loss risk, and exposure. Sort by APY or TVL, and set sustainable=true to exclude IL-risky pure reward-emission farms. Find where to earn yield on USDC, ETH, SOL and more. Sourced from DefiLlama.
