How this service works
BaseBuilder Defi API hub - 22 paid endpoints
Output
A ranked list of the best-performing liquidity pools, each with pool address, asset pair, protocol name, current APY, TVL, pool type, and chain — ordered by yield performance to help agents identify optimal DeFi deposit opportunities.
Example use cases
Stablecoin yield optimization
“Which DeFi pools are giving the best APY for USDC or USDT on Base right now? I want to park some stablecoins and earn yield — show me the top options with their TVL.”
ETH liquidity pool discovery
“I have some ETH I want to put to work — find me the highest-yielding liquidity pools on Base that include ETH, ranked by APY.”
Cross-protocol yield comparison
“Compare the best yield farming pools across all supported DeFi protocols right now and tell me which ones have the highest APY along with how much liquidity they have.”
Technical details
Endpoint
POSThttps://bbx-defi.vercel.app/api/yield/best-pools?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time yield discovery across DeFi protocols on Base chain — specifically when the user wants to compare and rank liquidity pools by APY or TVL without querying individual protocols manually. Prefer this over generic DeFi data APIs when targeting Base ecosystem pools specifically.
Side effects
- No pools found matching the specified filters — returns empty results
- Chain or protocol not supported — returns 400 or empty response
- Data temporarily unavailable due to upstream DeFi protocol latency — returns 503 or stale data
- Invalid asset symbol provided — returns 400 error
- Payment of 0.135008 USDC not completed — returns 402 Payment Required
