# zap_out_of_lp_position Maps to POST /removeliquidity/quote. Builds a single-transaction zap to exit an LP position into ANY output token — you can withdraw into any token, not just the pool's underlying tokens. SwapWizard handles LP burn, fee collection, and intermediate swaps in a single transaction. Supports an optional affiliateCode (registered affiliate wallet address) forwarded to the API so the affiliate fee is paid on-chain to that address. REQUIRED WORKFLOW: First call list_user_lp_positions, then pass the returned fields (positionId, nftManager, dexName, liquidityKind) here along with sender, poolId, and withdrawals. EXECUTION FLOW: (1) APPROVE — For NFT-based positions, call setApprovalForAll(router, true) on the nftManager contract (do NOT use approve(router, tokenId)). For PCS Infinity BIN, call approveForAll(router, true). For classic LP pools (Curve, Balancer, Uniswap V2, Solidly), approve the LP token as a standard ERC-20. (2) WAIT for the approve tx to be confirmed on-chain. (3) Call this tool again for a fresh quote (quotes expire). (4) Send the tx to the router contract: to=router, data=callData, value=value. This requires a private key or wallet signer. ⚠️ PRICE IMPACT: The response includes a priceImpact field. Agents MUST present this value to the user and request explicit confirmation before executing. Agent View of the PolicyLayer registry record for `zap_out_of_lp_position`.
