https://onchainpulse.theaslangroupllc.com/api/vault-apyGET /api/vault-apy · x402 API by onchainpulse
Live USDC yield panel on Base, read DIRECTLY from chain state — Aave v3, Compound v3, Moonwell, Euler v2 supply APY from onchain rate views, plus the six largest Morpho (MetaMorpho) USDC vaults with REALIZED trailing APY from ERC-4626 share-price deltas (archive reads, net of fees — not a vendor estimate). Optional: any custom ERC-4626 vault address on Base. Built for yield agents (Sail/Sailor, rebalancers, treasury bots) that need verify-before-acting numbers.
