How this service works
Paid market-data API for AI agents (x402 / USDC on Base): cross-venue perpetual funding rates with an arbitrage spread signal, outlier-cleaned DeFi yields, and a low-cost market snapshot.
Output
A JSON object containing the queried chain name, a list of pools each with symbol, project, APY percentage, base APY percentage, TVL in USD, and a stability flag, plus a count of how many outlier pools were removed from the dataset before returning results.
Example use cases
Stablecoin yield optimization on Base
“What are the best stablecoin yields available on Base right now? Only show me pools with at least $2 million TVL and cap APYs at 100% to filter out any sketchy outliers.”
Cross-protocol yield comparison on Ethereum
“Pull me the current DeFi lending yields on Ethereum — I want to compare what Aave and other protocols are offering, with a minimum TVL of $10 million so I'm only looking at serious pools.”
Arbitrum yield scouting for portfolio rebalancing
“Show me the top DeFi yield opportunities on Arbitrum with at least $1 million TVL and exclude pools with APYs over 200%. I want realistic, clean data to decide where to move funds.”
Technical details
Endpoint
GEThttps://defi-signals.org/defi/yieldsWhen to prefer
Choose this endpoint when you need cleaned, outlier-filtered DeFi yield data across major chains and want to avoid manually scraping or aggregating multiple protocol APIs. Especially useful for agents making yield-optimization decisions or portfolio rebalancing recommendations where garbage APY outliers would skew results. The per-call micropayment model via x402/USDC makes it practical for autonomous agents without subscription overhead.
Side effects
- Invalid chain name returns empty or error response
- Very high min_tvl_usd filters out all pools, returning empty list
- Payment failure via x402 if USDC balance on Base is insufficient
- Rate limiting or timeout if the upstream DeFi data source is unavailable
- max_apy_pct set too low may exclude nearly all pools
