How this service works
BaseBuilder Defi API hub - 22 paid endpoints
Output
Returns a list of stablecoin yield opportunities across DeFi protocols on Base, including protocol name, stablecoin ticker, current APY, TVL, yield source type (lending, liquidity provision, etc.), and risk tier.
Example use cases
Best USDC yield on Base
“What's the highest APY I can currently get for USDC across DeFi protocols on Base? I want to see a comparison of the top options with their TVL and yield sources.”
Safest stablecoin income strategy
“I have some DAI I want to earn yield on without taking on too much risk — can you pull up current stablecoin yield rates on Base and filter for the lower-risk protocols?”
Portfolio rebalancing yield check
“I'm rebalancing my DeFi portfolio and need to know which Base protocols are currently offering the best rates for stablecoins like USDC, USDT, and DAI — give me a ranked list by APY.”
Technical details
Endpoint
POSThttps://bbx-defi.vercel.app/api/yield/stablecoin?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need stablecoin yield data on the Base blockchain from a curated DeFi aggregator. Prefer this over generic DeFi aggregators when you need Base-native protocol coverage and are building automated yield-optimization workflows that require programmatic access with per-call pricing.
Side effects
- Protocol data unavailable or stale if underlying DeFi data source is down
- Empty result set if no protocols meet the filter criteria
- Payment required error (402) if USDC payment header is missing or insufficient
- Timeout if multiple protocol APIs are queried simultaneously
- Invalid parameter error if unsupported stablecoin ticker is provided
