jup-swap-api-client

Introduction

The jup-swap-api-client is a Rust client library designed to simplify the integration of the Jupiter Swap API, enabling seamless swaps on the Solana blockchain.

Getting Started

To use the jup-swap-api-client crate in your Rust project, follow these simple steps:

Add the crate to your Cargo.toml:

```toml
[dependencies]
jup-swap-api-client = "0.1.0"
```

Examples

Here's a simplified example of how to use the jup-swap-api-client in your Rust application:

use jupiter_swap_api_client::{
    quote::QuoteRequest, swap::SwapRequest, transaction_config::TransactionConfig,
    JupiterSwapApiClient,
};
use solana_sdk::pubkey::Pubkey;

const USDC_MINT: Pubkey = pubkey!("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");
const NATIVE_MINT: Pubkey = pubkey!("So11111111111111111111111111111111111111112");
const TEST_WALLET: Pubkey = pubkey!("2AQdpHJ2JpcEgPiATUXjQxA8QmafFegfQwSLWSprPicm");

#[tokio::main]
async fn main() {
    let jupiter_swap_api_client = JupiterSwapApiClient::new("https://quote-api.jup.ag/v6");

    let quote_request = QuoteRequest {
        amount: 1_000_000,
        input_mint: USDC_MINT,
        output_mint: NATIVE_MINT,
        slippage_bps: 50,
        ..QuoteRequest::default()
    };

    // GET /quote
    let quote_response = jupiter_swap_api_client.quote(&quote_request).await.unwrap();
    println!("{quote_response:#?}");

    // POST /swap
    let swap_response = jupiter_swap_api_client
        .swap(&SwapRequest {
            user_public_key: TEST_WALLET,
            quote_response: quote_response.clone(),
            config: TransactionConfig::default(),
        })
        .await
        .unwrap();

    println!("Raw tx len: {}", swap_response.swap_transaction.len());

    // Perform further actions as needed...

    // POST /swap-instructions
    let swap_instructions = jupiter_swap_api_client
        .swap_instructions(&SwapRequest {
            user_public_key: TEST_WALLET,
            quote_response,
            config: TransactionConfig::default(),
        })
        .await
        .unwrap();
    println!("{swap_instructions:#?}");
}

Using Self-hosted APIs

You can set custom URLs via environment variables for any self-hosted Jupiter APIs. Like the V6 Swap API or the paid hosted APIs. Here are the ENV vars:

API_BASE_URL=https://hosted.api

Paid Hosted APIs

You can also check out some of the paid hosted APIs.
