Meteora Zap SDK

A Typescript SDK for interacting with the Zap program on Meteora.

Overview

This SDK provides a set of tools and methods to interact with the Zap Program on Meteora. It enables developers to easily zap out of their positions on different AMMs on Solana.

Disclaimer: quotes, Direct routes, and examples

Zap In is a multi-step flow. Intermediate swap transactions are Jupiter (or pool) quotes that the SDK does not economically validate.

• simulateTransaction with no err only means the swap will land. It does not mean outAmount is a reasonable market vs the input size.
• Jupiter slippageBps bounds fill vs that quote / that route, not input-vs-output fair value. See Jupiter customer support.
• Direct zap-in helpers (estimateDlmmDirectSwap, and examples using maxAccounts: 50) currently call Jupiter with onlyDirectRoutes=true and maxAccounts=50. That can return a much thinner route than the Jupiter UI, which does not set those limits.
• The Meteora UI applies extra output-amount / USD / extreme-impact checks. This SDK does not. Examples are starting points for specific pools and sizes, not production-safe defaults for every token.

Before sending: compare quoted output to a reference price, reject extreme impact, simulate wallet token deltas, and if Direct is far worse than a multi-hop quote, pass onlyDirectRoutes=false / raise maxAccounts or skip the zap.

Installation

npm install @meteora-ag/zap-sdk
# or
pnpm install @meteora-ag/zap-sdk
# or
yarn add @meteora-ag/zap-sdk

Jupiter API Setup

All Jupiter-related functions (getJupiterQuote, getJupiterSwapInstruction, and estimate functions) support custom API configuration.

Getting Your Jupiter API Key

As of January 31st 2026, Jupiter requires an API key for all api request to https://api.jup.ag/. Obtain your API key at the Jupiter Portal

For detailed setup instructions, see Jupiter's Setup Guide.

API Parameters

All Jupiter functions accept optional jupiterApiUrl and jupiterApiKey parameters:

• jupiterApiUrl (optional): The Jupiter API endpoint. Default: "https://api.jup.ag"
• jupiterApiKey (optional): Your Jupiter API key. Default: "" (empty string)

Note: While the API key parameter is optional in the function signature, Jupiter requires an API key for all requests. Using the default empty string may result in API errors.

Initialization

import { Connection } from "@solana/web3.js";
import { Zap } from "@meteora-ag/zap-sdk";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const jupiterApiUrl = "https://api.jup.ag";
const jupiterApiKey = "YOUR_API_KEY_HERE";

const zap = new Zap(connection, jupiterApiUrl, jupiterApiKey);

Usage

Refer to the docs for how to use the functions.
