How this service works
USDC yield, best lending rates now ($0.002): supply and borrow APY of USDC on every Aave v3, Spark and Compound v3 market (Ethereum, Base, Arbitrum, Optimism, Polygon), utilization and size, highest APY first, read on chain every 10 minutes. Use to park idle USDC.
Output
A ranked list of USDC lending markets (highest supply APY first), each including protocol name, chain, supply APY, borrow APY, pool utilization percentage, and market TVL in USD. Data is refreshed on-chain every 10 minutes.
Example use cases
Idle USDC reallocation decision
“I have 50,000 USDC sitting idle — show me the best supply APYs available right now across all supported chains and protocols so I can decide where to deposit it.”
DeFi yield dashboard for a specific chain
“What are the current USDC supply and borrow rates on Arbitrum across Aave and Compound? Show me utilization and pool size too.”
Cheapest USDC borrowing source
“I need to borrow USDC against collateral — which protocol and chain is offering the lowest borrow APY right now across Aave v3, Spark, and Compound v3?”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/markets/usdc-yield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, multi-protocol, multi-chain USDC lending and borrowing rates in a single call. It is purpose-built for idle USDC allocation decisions and covers all major DeFi money markets (Aave v3, Spark, Compound v3) simultaneously. Prefer it over general market data APIs when the question is specifically about stablecoin yield or DeFi money market rates.
Side effects
- Invalid chain value returns 400 or empty results
- Invalid protocol name returns empty result set
- minTvlUsd too high filters out all markets, returning empty array
- Network timeout during on-chain read returns 503 or stale data
- Rate limiting if calls exceed account quota
