Get Quote

Please use the Swap API at your own discretion.

The Jupiter UI at https://jup.ag/ contains multiple safeguards, warnings and default settings to guide our users to trade safer. Jupiter is not liable for losses incurred by users on other platforms.

If you need clarification or support, please reach out to us in Discord.

Routing Engine

The quotes from Swap API are from the Jupiter Metis v1 Routing Engine.

The Quote API enables you to tap into the Jupiter Metis v1 Routing Engine, which accesses the deep liquidity available within the DEXes of Solana's DeFi ecosystem. In this guide, we will walkthrough how you can get a quote for a specific token pair and other related parameters.

Let’s Get Started

In this guide, we will be using the Solana web3.js package.

If you have not set up your environment to use the necessary libraries and the connection to the Solana network, please head over to Environment Setup.

API Reference

To fully utilize the Quote API, check out the Quote API Reference.

The most common trading pair on Solana is SOL and USDC, to get a quote for this specific token pair, you need to pass in the required parameters such as:

Parameters	Description
inputMint	The pubkey or token mint address e.g. So11111111111111111111111111111111111111112
outputMint	The pubkey or token mint address e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v
amount	The number of input tokens before the decimal is applied, also known as the “raw amount” or “integer amount” in lamports for SOL or atomic units for all other tokens.
slippageBps	The number of basis points you can tolerate to lose during time of execution. e.g. 1% = 100bps

Get Quote

Using the root URL and parameters to pass in, it is as simple as the example code below!

const quoteResponse = await (
    await fetch(
        'https://lite-api.jup.ag/swap/v1/quote?inputMint=So11111111111111111111111111111111111111112&outputMint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v&amount=100000000&slippageBps=50&restrictIntermediateTokens=true'
    )
  ).json();
  
console.log(JSON.stringify(quoteResponse, null, 2));

Example response:

      "percent": 100
    }
  ],
  "contextSlot": 299283763,
  "timeTaken": 0.015257836
}

tip

outAmount refers to the best possible output amount based on the route at time of quote, this means that slippageBps does not affect.

What’s Next

Now, you are able to get a quote, next steps is to submit a transaction to execute the swap based on the quote given. Let’s go!

Additional Resources

Restrict Intermediate Tokens

restrictIntermediateTokens can be set to true . If your route is routed through random intermediate tokens, it will fail more frequently. With this, we make sure that your route is only routed through highly liquid intermediate tokens to give you the best price and more stable route.

Legacy Transactions

All Jupiter swaps are using Versioned Transactions and Address Lookup Tables. However, not all wallets support Versioned Transactions yet, so if you detect a wallet that does not support versioned transactions, you will need to set the asLegacyTransaction parameter to true.

Adding Fees

By using the Quote API in your app, you can add a fee to charge your users. You can refer to the platformFeeBps parameter and to add it to your quote and in conjuction, add feeAccount (it can be any valid token account) to your swap request.

Direct Routes

In some cases, you may want to restrict the routing to only go through 1 market. You can use the onlyDirectRoutes parameter to achieve this. This will ensure routing will only go through 1 market.

note

• If there are no direct routes, there will be no quote.
• If there is only 1 market but it is illiquid, it will still return the route with the illiquid market.

unfavorable trades

Please be aware that using onlyDirectRoutes can often yield unfavorable trades or outcomes.

Max Accounts

In some cases, you may want to add more accounts to the transaction for specific use cases, but it might exceed the transaction size limit. You can use the maxAccounts parameter to limit the number of accounts in the transaction.

unfavorable trades

Please be aware that the misuse of maxAccounts can yield unfavorable trades or outcomes.

tip

• Refer to the Requote with Lower Max Accounts guide for more information on how to requote and adjust the swap when using maxAccounts.

note

• maxAccounts is an estimation and the actual number of accounts may vary.
• maxAccounts only applies to the total number of accounts of the inner swaps in the swap instruction and not any of the setup, cleanup or other instructions (see the example below).
• We recommend setting maxAccounts to 64
• Keep maxAccounts as large as possible, only reduce maxAccounts if you exceed the transaction size limit.
• If maxAccounts is set too low, example to 30, the computed route may drop DEXes/AMMs like Meteora DLMM that require more than 30 accounts.

Jupiter has 2 types of routing instructions, if you plan to limit maxAccounts, you will need to account for if the market is routable with ALTs or not:

• Routing Instruction (Simple Routing): The market is still new, and we do not have ALTs set up for the market, hence the number of accounts required is higher as there are more accounts required.
• Shared Accounts Routing Instruction: The market has sufficient liquidity (and has been live for a while), and we have ALTs set up for the market to be used in the routing instruction, hence the number of accounts required is lower as there are less accounts required.

Counting the accounts using an example transaction

In this transaction:

• You can see that there are a total of 2 inner swaps where the number of accounts respectively are
  • Stabble Stable Swap: 12
  • Lifinity Swap V2: 13
  • Total: 25
• The maxAccounts parameter is to control this value - to limit the total number of accounts in the inner swaps.
• It doesn’t take into the consideration of a few things:
  • Each of the inner swap's program address, so 2 in this case.
  • Top level routing instruction accounts where in this case Shared Accounts Route is 13 and Route is 9.
  • There are also other accounts that are required to set up, clean up, etc which are not counted in the maxAccounts parameter

List of DEXes and their required accounts

Notes:

• Values in the table are only estimations and the actual number of accounts may vary.
• Min accounts are needed when we have already created the necessary ALTs for a specific pool resulting in less accounts needed in a Shared Accounts Routing context.
• Sanctum and Sanctum Infinity are unique, and their accounts are dynamic.
