Call it before `decrease-tx` to show the user the real payout. Meteora DLMM positions only. **Solana only** - this endpoint has no Robinhood Chain (EVM) equivalent. Replaces `POST /position/decrease-quotes`, which has been removed. ## OpenAPI ````yaml /api-reference/openapi.json post /position/zap-out-estimates openapi: 3.0.0 info: title: LP Agent Open API version: 1.0.0 description: |+ Public API for LP Agent **Authentication** All endpoints require an API key passed via the `x-api-key` header. servers: - url: https://api.lpagent.io/open-api/v1 description: Production security: - apiKeyAuth: [] tags: [] paths: /position/zap-out-estimates: post: tags: - Position summary: Zap-Out - Estimate what a withdrawal pays out description: > For each output option of `decrease-tx`, returns what the wallet ends up with after the swap and fees, priced on the route the transaction is built on: net amounts, their value in SOL and USD, and the same withdrawal's value at the pool price before any swap.
