GET /swap/v1/quote
Get an easy-to-consume quote for buying or selling any ERC20 token. The return format is a valid unsigned Ethereum transaction and can be submitted directly to an Ethereum node (or the nodes of other chains if applicable) to complete the swap. For transactions where the sellToken is not ETH, you will have to set your allowances.
Request​
Either a sellAmount or buyAmount is required.
| Query Param | Description | Example |
|---|---|---|
sellToken | The ERC20 token address or symbol of the token you want to send. Native token such as "ETH" can be provided as a valid sellToken. If the symbol given is not supported, try using token address instead. | sellToken=ETH, sellToken=0x6b175474e89094c44da98b954eedeac495271d0f |
buyToken | The ERC20 token address or symbol of the token you want to receive. Native token such as "ETH" can be provided as a valid buyToken.If the symbol given is not supported, try using token address instead. | buyToken=ETH, buyToken=0x6b175474e89094c44da98b954eedeac495271d0f |
sellAmount | (Optional) The amount of sellToken (in sellToken base units) you want to send. | sellAmount=100000000000 |
buyAmount | (Optional) The amount of buyToken(in buyToken base units) you want to receive. | buyAmount=100000000000 |
slippagePercentage | (Optional, default is 0.01 for 1%) The maximum acceptable slippage of the buyToken amount if sellAmount is provided; The maximum acceptable slippage of the sellAmount amount if buyAmount is provided (e.g. 0.03 for 3% slippage allowed). The lowest possible value that can be set for this parameter is 0; in other words, no amount of slippage would be allowed. If no value for this optional parameter is provided in the API request, the default slippage percentage is 1%. | slippagePercentage=0.03 |
gasPrice | (Optional, defaults to ethgasstation "fast") The target gas price (in wei) for the swap transaction. If the price is too low to achieve the quote, an error will be returned. | gasPrice=1000000 |
takerAddress | (Optional) The address which will fill the quote. While optional, we highly recommend providing this parameter if possible so that the API can more accurately estimate the gas required for the swap transaction. This helps when vaildating the entire transaction for success, and catches revert issues. If the validation fails, a Revert Error will be returned in the response. The quote should be fillable if this address is provided. Also, make sure this address has enough token balance. Additionally, including the takerAddress is required if you want to integrate RFQ liquidity. | takerAddress=0xa8aac589a67ecfade31efde49a062cc21d68a64e |
excludedSources | (Optional) Liquidity sources (Uniswap, SushiSwap, 0x, Curve, etc) that will not be included in the provided quote. See here for a full list of sources. This parameter cannot be combined with includedSources. | excludedSources=Uniswap,SushiSwap,Curve |
includedSources | (Optional) Typically used to filter for RFQ liquidity without any other DEX orders which this is useful for testing your RFQ integration. To do so, set it to 0x. This parameter cannot be combined with excludedSources. | includedSources=0x |
skipValidation | (Optional) Normally, whenever a takerAddress is provided, the API will validate the quote for the user. For more details, see "How does takerAddress help with catching issues?" When this parameter is set to true, that validation will be skipped. Also see Quote Validation here. For /quote , the default of skipValidation=false but can be overridden to true . | skipValidation=false |
intentOnFilling | (Optional) Used to enable RFQ liquidity. For more details see the guide here . | intentOnFilling=true |
feeRecipient | (Optional) The ETH address that should receive affiliate fees specified with buyTokenPercentageFee . Can be used combination with buyTokenPercentageFee to set a commission/trading fee when using the API. Learn more about how to setup a trading fee/commission fee/transaction fee here in the FAQs. | feeRecipient=0xa8aac589a67ecfade31efde49a062cc21d68a64e |
buyTokenPercentageFee | (Optional) The percentage (denoted as a decimal between 0 - 1.0 where 1.0 represents 100%) of the buyAmount that should be attributed to feeRecipient as affiliate fees. Note that this requires that the feeRecipient parameter is also specified in the request. Learn more about how to setup a trading fee/commission fee/transaction fee here in the FAQs. | buyTokenPercentageFee=0.1 |
enableSlippageProtection | (Optional) A boolean field, set to true or false. If enableSlippageProtection is either not set or set to true, the quote will be adjusted for MEV-aware slippage. If enableSlippageProtection is false, the quote returned will not be adjusted for MEV-aware slippage (this is recommended for meta-aggregators & integrators who will compare the quoted price with other sources). See affects on buyAmount , price , and expectedSlippage in the Response fields. Read more about Slippage Protection . | enableSlippageProtection=true |
priceImpactProtectionPercentage | (Optional, defaults to 100%) The percentage (between 0 - 1.0) of allowed price impact. When priceImpactProtectionPercentage is set, estimatedPriceImpact is returned which estimates the change in the price of the specified asset that would be caused by the executed swap due to price impact. If the estimated price impact is above the percentage indicated, an error will be returned. For example, if PriceImpactProtectionPercentage=.15 (15%), any quote with a price impact higher than 15% will return an error. This is an opt-in feature, the default value of 1.0 will disable the feature. When it is set to 1.0 (100%) it means that every transaction is allowed to pass. Note: When we fail to calculate Price Impact we will return null and Price Impact Protection will be disabled See affects on estimatedPriceImpact in the Response fields. Read more about price impact protection and how to set it up here. | priceImpactProtectionPercentage=0.15 |
feeRecipientTradeSurplus | (Optional) The recipient of any trade surplus fees. If specified, this will collect trade surplus when applicable. Otherwise, trade surplus will not be collected. | feeRecipientTradeSurplus=0xa8aac589a67ecfade31efde49a062cc21d68a64e |
Response​
| Field | Description |
|---|---|
price | If buyAmount was specified in the request it provides the price of buyToken in sellToken and vice versa. This price does not include the slippage provided in the request above, and therefore represents the best possible price. If buyTokenPercentageFee and feeRecipientwere set, the fee amount will be part of this returned price. If enableSlippageProtection in the request was not false, the buyAmount & price responses returned will factor slippage in its routing. |
grossPrice | Similar to price but with fees removed in the price calculation. This is the price as if no fee is charged. |
guaranteedPrice | The price which must be met or else the entire transaction will revert. This price is influenced by the slippagePercentage parameter. On-chain sources may encounter price movements from quote to settlement. |
estimatedPriceImpact | When priceImpactProtectionPercentage is set, this value returns the estimated change in the price of the specified asset that would be caused by the executed swap due to [price impact(/0x-swap-api/advanced-topics/price-impact-protection)]. Note: If we fail to estimate price change we will return null. Read more about price impact protection and how to set it up here . |
to | The address of the contract to send call data to. |
data | The call data required to be sent to the to contract address. |
value | The amount of ether (in wei) that should be sent with the transaction. (Assuming protocolFee is paid in ether). |
gasPrice | The gas price (in wei) that should be used to send the transaction. The transaction needs to be sent with this gasPrice or lower for the transaction to be successful. |
gas | The estimated gas limit that should be used to send the transaction to guarantee settlement. While a computed estimate is returned in all responses, an accurate estimate will only be returned if a takerAddress is included in the request. |
estimatedGas | The estimate for the amount of gas that will actually be used in the transaction. Always less than gas. |
protocolFee | The maximum amount of ether that will be paid towards the protocol fee (in wei), and what is used to compute the value field of the transaction. |
minimumProtocolFee | The minimum amount of ether that will be paid towards the protocol fee (in wei) during the transaction. |
buyAmount | The amount of buyToken (in buyToken units) that would be bought in this swap. Certain on-chain sources do not allow specifying buyAmount, when using buyAmount these sources are excluded. |
grossBuyAmount | Similar to buyAmount but with fees removed. This is the buyAmount as if no fee is charged. |
sellAmount | The amount of sellToken (in sellToken units) that would be sold in this swap. Specifying sellAmount is the recommended way to interact with 0xAPI as it covers all on-chain sources. |
grossSellAmount | Similar to sellAmount but with fees removed. This is the sellAmount as if no fee is charged. Note: Currently, this will be the same as sellAmount as fees can only be configured to occur on the buyToken. |
sources | The percentage distribution of buyAmount or sellAmount split between each liquidity source. Ex: [{ name: '0x', proportion: "0.8" }, { name: 'Kyber', proportion: "0.2"}, ...] |
buyTokenAddress | The ERC20 token address of the token you want to receive in quote. |
sellTokenAddress | The ERC20 token address of the token you want to sell with quote. |
allowanceTarget | The target contract address for which the user needs to have an allowance in order to be able to complete the swap. For swaps with "ETH" as sellToken, wrapping "ETH" to "WETH" or unwrapping "WETH" to "ETH" no allowance is needed, a null address of 0x0000000000000000000000000000000000000000 is then returned instead. |
orders | The details of fill orders |
sellTokenToEthRate | The rate between ETH and sellToken |
buyTokenToEthRate | The rate between ETH and buyToken |
expectedSlippage | This is the expected slippage used in routing calculations for the quote returned. It is the value of slippage that we estimate that the selected route will have: - It can be used by integrators to calculate the Final Expected Amount for the asset: i.e. calculated as ( buyAmount * expectedSlippage ) - It will only be returned when enableSlippageProtection is not set to false |
fees | Fees that would be charged. It can contain zeroExFee. See details about this fee type below. |
zeroExFee | Related to fees param above. Fee that 0x charges:   - feeType: volume which means 0x would charge a certain percentage of the trade.   - feeToken: The ERC20 token address to charge fee.   - feeAmount: The amount of feeToken to be charged as 0x fee.   - billingType: The method that 0x fee is transferred. It can currently only be on-chain which means the fee would be charged on-chain. |

Wrapping and unwrapping between ETH and WETH​
Easily wrap and unwrap between ETH and WETH by requesting a swap quote by setting sellToken and 'buyToken' as either 'WETH' or 'ETH'. The swap quote returned will provide the calldata to directly interact with the WETH9 contract and not with 0x exchange contracts.
