How this service works
DeFi yields now ($0.002): best supply and borrow APY of every Aave v3, Spark and Compound v3 market on Ethereum, Base, Arbitrum, Optimism and Polygon, read on chain every 10 minutes, highest APY first, filter by asset, chain or protocol. Use to find where stablecoins or ETH earn most.
Output
A ranked list of DeFi lending markets (up to the requested limit), each showing the asset, protocol, chain, supply APY, borrow APY, and TVL in USD, sorted highest APY first. Data is refreshed from on-chain sources every 10 minutes.
Example use cases
Best stablecoin yield across chains
“Where can I earn the most by supplying USDC right now? Check Aave v3, Spark, and Compound v3 across Ethereum, Base, Arbitrum, Optimism, and Polygon — show the top 5 markets sorted by APY.”
Cheapest DeFi borrowing rate for ETH
“I want to borrow WETH in DeFi — which protocol and chain gives me the lowest borrow APY right now? Only show markets with at least $2M in liquidity.”
Protocol-specific yield comparison
“Compare current supply APY for USDT across all Aave v3 markets on Arbitrum and Optimism — I want to know which chain is paying more right now.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/markets/defi-yields?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, on-chain DeFi yield data across multiple major lending protocols and EVM chains in a single call. Prefer this over manual protocol queries when comparing Aave v3, Spark, and Compound v3 simultaneously, or when you need asset- or chain-specific filtering with TVL constraints. Ideal for agents making yield optimization decisions or routing capital to the highest-earning market.
Side effects
- Unsupported asset symbol returns empty results or error
- Invalid chain or protocol enum value returns 400 or empty list
- minTvlUsd set too high filters out all markets, returning empty array
- On-chain data temporarily stale if refresh cycle is delayed
- Rate limit or payment failure returns 402 or 429 error
