payable

Build unsigned transactions to enter any DeFi yield — native/liquid staking (ETH, SOL, ATOM), stablecoin lending (USDC/USDT on Aave, Morpho), ERC-4626 vaults, and tokenized RWAs across 80+ networks. Does NOT execute: the caller signs and broadcasts each tx, so keys never leave the caller. Find yield IDs via yields_get_all.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
