How this service works
DeFi yields and lending rates, live APY ($0.002): supply and borrow APY, utilization and USD size of every Aave v3 (Ethereum, Base, Arbitrum, Optimism, Polygon), Spark and Compound v3 market, read on chain every 10 minutes, highest supply APY first, with the best USDC, USDT, WETH, WBTC and DAI rate. Filter by asset (or stablecoins), chain, protocol and minimum TVL. Use to find where idle stablecoins or ETH earn most.
Output
A ranked JSON array of lending markets, each containing the protocol name, chain, asset symbol, supply APY, borrow APY, utilization rate, and total supplied in USD — ordered by highest supply APY first, filtered per the query parameters.
Example use cases
Maximizing idle stablecoin yield
“I have idle USDC sitting in my wallet — where across Aave v3, Spark, and Compound on Ethereum, Arbitrum, and Base can I earn the most right now? Only show markets with at least $2 million in liquidity.”
Comparing WETH borrow costs across chains
“I want to borrow WETH as cheaply as possible — can you pull the current borrow APYs for WETH across all supported chains on Aave v3 and Compound v3 and tell me where the rate is lowest?”
Monitoring Polygon DeFi market utilization
“Show me all lending markets on Polygon with a TVL of at least $5 million — I want to see supply APY, borrow APY, and utilization rate for each one so I can spot any that are getting close to full capacity.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/markets/yields?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, cross-protocol DeFi lending rates in a single call — especially when comparing supply or borrow APYs across Aave v3, Spark, and Compound v3 simultaneously. It is the right choice over scraping protocol UIs or calling individual protocol APIs because it normalizes data across five chains and three protocols, refreshes every 10 minutes, and returns results ranked by APY. Prefer it when the user wants to optimize yield on stablecoins or ETH, understand market utilization, or monitor lending market conditions programmatically.
Side effects
- Invalid or unsupported asset symbol returns an empty result set
- Chain or protocol enum value misspelled returns a 400 validation error
- minTvlUsd set too high filters out all markets, returning an empty array
- Payment not sent or insufficient USDC balance results in a 402 Payment Required error
- On-chain data temporarily unavailable during indexing window returns stale or partial data
