-# JavaScript API Client for Jupiter V6
+Jupiter V6 JavaScript API Client
 
-## Table of Contents
+A robust client library for interacting with the Jupiter Swap API (V6). Use this package to easily fetch quotes and build swap transactions on the Solana network.

-## Installation
+Prerequisites
 
-To use the Jupiter API client, you need to have Node.js and npm (Node Package Manager) installed. Then, you can install the package using npm:

+
+Resources
+
+Prerequisites
+
+To use this client, ensure you have the following installed:
+
+Node.js (v18 or higher recommended)
+
+npm or pnpm (Node Package Manager)
+
+Installation
+
+Install the package via npm or pnpm:
 
-```bash
 npm install @jup-ag/api
-```
+# or
+pnpm install @jup-ag/api
 
-## Developing
 
-- pnpm dev-quote
-  - Get request a quote based on mints and amount
-- pnpm dev-swap
-  - Post request with the quote response to receive the swap transaction to sign and send to the network
-  - Ensure you have setup `process.env.PRIVATE_KEY` to sign
- 
-- Please set up `process.env.API_KEY` if you have a Pro plan via https://portal.jup.ag/
+Configuration and Authentication
 
-Refer to our developer documentation for more information and tips:
-- Swap API: https://dev.jup.ag/docs/swap-api
-- API Key setup: https://dev.jup.ag/docs/api-setup
+For production use and premium features, setting up environment variables is required.
 
-## Usage
+API Key (Pro Plan Access)
 
-To start using the API client, you need to require it in your Node.js project:
+If you are on a Pro plan, you must set your API key to access rate-limited or premium endpoints:
+
+# In your .env file or environment
+export API_KEY="YOUR_JUPITER_PRO_API_KEY"
+
+
+The client will automatically pick up process.env.API_KEY during initialization if passed without a specific configuration object.
+
+Private Key (For Swap Execution)
+
+To sign and execute a swap transaction, you must provide your wallet's private key. This is typically used in the backend for the dev-swap script:
+
+# In your .env file or environment
+export PRIVATE_KEY="YOUR_WALLET_PRIVATE_KEY"
+
+
+Usage
+
+Initialization
+
+Import the client factory and create an instance. The config object is optional, primarily for passing the API key or custom fetch configurations.
 
-```typescript
 import { createJupiterApiClient } from '@jup-ag/api';
 
-const jupiterQuoteApi = createJupiterApiClient(config); // config is optional such as api key
-```
+// Configuration is optional, the client will look for process.env.API_KEY automatically
+// if you are using Pro features.
+const jupiterQuoteApi = createJupiterApiClient(/* config */);
+
+
+Getting a Quote
+
+Use the quoteGet method to fetch the best route for a swap.
 
-Now, you can call methods provided by the API client to interact with Jupiter's API. For example:
+Important Note on Amount: The amount field must be specified in the smallest unit (Lamports) of the input token. For example, to swap 0.1 SOL, which has 9 decimal places, the amount should be 100000000.
 
-```typescript
 jupiterQuoteApi.quoteGet({
-    inputMint: "So11111111111111111111111111111111111111112",
+    // Standard Solana WSOL address
+    inputMint: "So11111111111111111111111111111111111111112", 
+    // USDC (Example)
     outputMint: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
+    // Example: 0.1 SOL (100,000,000 Lamports)
     amount: "100000000",
+    // Slippage tolerance in basis points (100 BPS = 1%)
     slippageBps: 100,
-})
-```
+});
+
+
+Executing a Swap
+
+The swap process is two-fold:
+
+Get Quote: Call jupiterQuoteApi.quoteGet to receive a QuoteResponse object.
+
+Get Swap Transaction: Pass the entire QuoteResponse object to the swapPost method. This returns a serialized transaction that needs to be signed and sent to the network.
+
+// Assumes 'quoteResponse' is the result from jupiterQuoteApi.quoteGet
+const swapTransaction = await jupiterQuoteApi.swapPost({
+    swapRequest: quoteResponse
+});
+
+// The returned transaction must be signed and broadcasted to the Solana network.
+// Ensure process.env.PRIVATE_KEY is set for local testing/development.
+
+
+Local Development
+
+The following pnpm scripts are available for testing the client functionality locally:
+
+Script
+
+Method
+
+Description
+
+Requirements
+
+pnpm dev-quote
+
+GET /quote
+
+Fetches and displays the best swap quote for pre-configured mints and amounts.
+
+None
+
+pnpm dev-swap
+
+POST /swap
+
+Executes a swap transaction based on a retrieved quote.
+
+process.env.PRIVATE_KEY must be set for signing.
