Barker

Barker is a real-time stablecoin yield index and AI advisor that routes idle stablecoins to the best on-chain yield across 500+ protocols and 50+ exchange programs. It evaluates depeg, counterparty, and smart-contract risk before returning a non-custodial deposit or redeem quote that settles on-chain. Agent access is exposed as a native MCP endpoint using x402 micropayments, and no private keys or wallet addresses are ever transmitted to the API.
