solana_kit_jupiter 0.9.1

Jupiter Exchange client for Solana Kit Dart — Swap API v2 (order/execute and raw build), Price v3, and Token v2 APIs.

solana_kit_jupiter

Jupiter Exchange client for the Solana Kit Dart SDK: the Swap API v2 (quote, assembled transaction, execution, and raw build), Price API v3, and Token API v2, with Solana Kit transaction decoding.

What you get

• Swap API v2 — request a quote plus an assembled v0 transaction (/swap/v2/order), submit the signed transaction for managed execution (/swap/v2/execute), or fetch the raw instruction set for self-landing swaps (/swap/v2/build)
• Price API v3 — USD prices for up to fifty mints per request
• Token API v2 — search, tag, category, and recent token metadata
• Transaction decode — turn the returned base64 wire transaction into a typed Transaction for inspection and signing
• Injectable transport — pass a custom HTTP client through JupiterConfig for tests and middleware

Out of v1 scope: the Trigger API (limit orders and DCA), the Referral on-chain program, Lend, Prediction, Studio, and the Jupiter Terminal web widget (which cannot serve Dart or Flutter apps).

Auth

All endpoints accept an optional x-api-key header. Without a key, Jupiter serves keyless traffic on https://api.jup.ag at a reduced rate limit; keys from the Jupiter developer portal unlock higher tiers on the same base URL.

Installation

Install the package directly:

dependencies:
  "solana_kit_jupiter": ^

If your app uses several Solana Kit packages together, you can also depend on the umbrella package instead:

dart pub add solana_kit

Inside this monorepo, Dart workspace resolution uses the local package automatically.

Usage

Swap through Jupiter's managed order flow

/order returns a quote plus an assembled v0 transaction; sign it with Solana Kit signers and submit it through /execute.

import 'package:solana_kit_addresses/solana_kit_addresses.dart';
import 'package:solana_kit_jupiter/solana_kit_jupiter.dart';

Future<void> main() async {
  const solAddress = Address('So11111111111111111111111111111111111111112');
  const usdcAddress = Address(
    'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v',
  );

  final jupiter = createJupiterClient(JupiterConfig(apiKey: 'your-api-key'));

  final order = await jupiter.swap.getOrder(
    JupiterOrderRequest(
      inputMint: solAddress,
      outputMint: usdcAddress,
      amount: BigInt.from(10000000), // 0.01 SOL
      slippageBps: 50,
    ),
  );

  final transaction = decodeBase64SwapTransaction(order.encodedTransaction!);
  // Inspect, sign the transaction with solana_kit_signers, then submit it.
  print(transaction);
}

For self-landing swaps, use jupiter.swap.buildSwap(...) to fetch the raw instruction set instead of the assembled transaction.
