Actions Exit

by Yield.xyz MCP in Onchain & crypto

x402 APIPassing, checked 2 h ago

Build unsigned transactions to exit a DeFi yield position — unstake, withdraw from lending or vaults, or redeem RWAs — across 80+ networks. Supports instant and queued/cooldown redemption per protocol. Does NOT execute: the caller signs and broadcasts each tx. Check positions with yields_get_balances first.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.001.
