Output
A ranked list of DeFi pool opportunities sorted by APY, each entry including pool/protocol name, chain, base APY, reward APY, total APY, TVL, impermanent loss risk indicator, and a stablecoin flag — aggregated from 16,000+ pools.
Example use cases
Stablecoin yield optimization on Base
“What are the top stablecoin yield pools on Base right now? I want at least $500,000 TVL and I only care about low-IL-risk options — show me the best APY with breakdown of base vs reward rates.”
Multi-chain USDC farming comparison
“Compare the best USDC yield opportunities across Ethereum, Arbitrum, and Base — filter for pools with at least $1 million in TVL and sort by total APY so I can see where to deploy capital.”
New DeFi strategy research for ETH holders
“I'm holding ETH and want to put it to work — find me the highest APY liquidity pools for WETH or ETH with a minimum TVL of $200,000, including the impermanent loss risk level for each.”
Technical details
Endpoint
POSThttps://api.x-402.online/v1/defi/yieldsWhen to prefer
Choose this endpoint when you need a broad, aggregated view of DeFi yield opportunities across thousands of pools in a single call, especially when filtering by specific token and chain with a TVL floor. Prefer it over individual protocol APIs when you want cross-protocol APY comparison with IL risk and stablecoin metadata already included. Not suitable for real-time price execution or on-chain transactions.
Side effects
- Invalid or unsupported token symbol returns empty results or 400 error
- Unsupported chain name returns no results
- min_tvl set too high may return zero pools
- Stale data if underlying pool data sources are temporarily unavailable
- Rate limiting or payment failure returns 402 or 429 error
