How this service works
Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.
Output
Returns a JSON object with a count of matching pools, a timestamp (generatedAt), and an array of pool objects each containing project name, token symbol, chain, TVL in USD, total APY (base + reward split), pool ID, impermanent loss risk flag, and stablecoin classification.
Example use cases
Best stablecoin yields on Ethereum
“Find me the top 10 stablecoin-only DeFi pools on Ethereum with at least $10M TVL, sorted by highest APY.”
Cross-chain yield comparison for ETH pools
“What are the top 50 DeFi pools across all chains sorted by TVL, with a minimum of $1M TVL? I want to compare yields across Arbitrum, Base, and Ethereum.”
Highest APY farming opportunities on Arbitrum
“Pull the top 20 highest-APY liquidity pools on Arbitrum with at least $10M TVL so I can find the best yield farming opportunities right now.”
Technical details
Endpoint
GEThttps://4yearcycle.com/x402/defi-yieldsWhen to prefer
Choose this endpoint when you need ranked, filterable DeFi yield data sourced from DefiLlama with minimal setup — ideal for agents comparing cross-chain APY opportunities, building yield dashboards, or screening pools by TVL and chain without running your own DefiLlama queries.
Side effects
- Invalid chain name returns empty pool list or unfiltered results
- top value above 100 is silently capped at 100
- minTvlUsd with non-integer string may cause validation error
- DefiLlama upstream outage returns stale or empty data
- Payment not accepted returns HTTP 402
