How this service works
Supply yield for an asset on the most used lending markets (Aave v3, Morpho, Compound v3, Spark, Euler, Fluid) by chain: total, base and reward APY and TVL, best first.
Output
Returns a JSON object with a ranked list of lending markets for the requested token and network, each including: protocol name, chain, total APY (%), base APY (%), incentives/reward APY (%), TVL in USD, a unique market ID, and optional vault info. Also includes top-level metadata: token symbol, data source (DefiLlama), total number of markets found, and the queried network.
Example use cases
Best stablecoin lending rate on Ethereum
“Find me the highest supply APY for USDC on Ethereum across Aave, Morpho, Compound, Spark, and Euler — I want to see total APY broken down into base and reward, and the TVL for each market, best first.”
Cross-protocol yield comparison for ETH
“Compare the current lending yields for WETH across all major DeFi protocols on Arbitrum — I need total APY, the base rate, any reward incentives, and the TVL so I can decide where to deposit.”
Reward-boosted lending opportunity scan
“Which protocol on Base is offering the highest incentive reward APY for lending USDC right now? Show me the top 3 markets with their base and reward APY split and TVL.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/lending-yields?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a ranked, multi-protocol comparison of DeFi lending supply yields for a specific token on a specific chain. It aggregates data from the six most prominent lending protocols (Aave v3, Morpho, Compound v3, Spark, Euler, Fluid) and breaks APY into base and reward components, which is essential for distinguishing sustainable yields from incentive-boosted ones. Prefer this over general DeFi yield aggregators when you need structured, LLM-ready data with TVL signals and protocol-level granularity on the lending side specifically (not liquidity pools).
Side effects
- Token not supported or not found on the specified network — returns empty or null results
- Network/chain name not recognized — may return no results or an error
- Rate limit or payment failure — returns HTTP error if x402 payment not processed
- DefiLlama data source temporarily unavailable — stale or missing data
- Limit parameter set too high — may slow response or return partial results
