How this service works
Query real-time stablecoin supply yield pools from Barker's index of 500+ DeFi protocols. Returns ranked rows with protocol_name, chain_name, asset_symbol, supply_apy_total (decimal — multiply by 100 for %), and supply_tvl (USD). Use for questions like 'best stablecoin yield', 'where to earn on USDC', 'compare lending rates', '稳定币利率'.
Output
Returns ranked rows, each containing protocol_name, chain_name, asset_symbol, supply_apy_total (decimal — multiply by 100 for percent), and supply_tvl (USD). Results can be sorted by APY or TVL and filtered by specific stablecoin asset and/or blockchain chain.
Example use cases
Best USDC yield on Arbitrum
“What are the best places to earn yield on USDC right now on Arbitrum? Show me the top 10 pools sorted by APY.”
Compare stablecoin rates across protocols
“I want to compare lending rates for USDT across all chains — give me the top 50 pools sorted by APY so I can see which DeFi protocols are paying the most.”
Largest stablecoin pools by TVL
“Which stablecoin yield pools have the most liquidity on Base? Sort by TVL and show me the top 25 so I can find the most battle-tested options.”
Technical details
Endpoint
GEThttps://mcp.barker.money/barker_defi_vaults?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a broad ranked survey of stablecoin yield opportunities across many protocols and chains simultaneously — ideal for comparison, discovery, and screening. Prefer this over single-pool dossier endpoints when you don't know which specific pool to look up, or when the user wants to see ranked options rather than details on one pool.
Side effects
- Invalid asset symbol returns empty results or error
- Invalid chain name returns empty results or error
- sort parameter must be exactly 'apy' or 'tvl' — other values rejected
- limit exceeding 100 returns validation error
- Real-time data may have brief staleness during protocol indexing refresh
