Description of query parameters

Parameter name	Type	Description
src*	string	contract address of a token to sell e.g.: 0x6b175474e89094c44da98b954eedeac495271d0f
dst*	string	contract address of a token to buy e.g.: 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
amount*	integer	amount of a token to sell, set in minimal divisible units e.g.: 1.00 DAI set as 1000000000000000000 51.03 USDC set as 51030000
includeTokensInfo	boolean	if set to true, response will include from token and to token info default: false
includeProtocols	boolean	if set to true, response will include protocols used in the quote default: false
includeGas	boolean	if set to true, response will include gas limit anticipated for the quote default: false
fee	number	this percentage of src token amount will be sent to referrerAddress, the rest will be used as input for a swap min: 0; max: 3; default: 0; example to set a fee to 1.5%: &fee=1.5
protocols	string	specify liquidity protocols to use. If not set, all liquidity protocols will be used e.g.: &protocols=WETH,CURVE,BALANCER,...,ZRX default: all protocols can be used
gasPrice	string	1inch takes in account gas expenses to determine exchange route. It is important to use the same gas price on the quote and swap methods gas price set in wei: 12.5 GWEI set as 12500000000 default: "fast" from the network
complexityLevel	string	maximum number of token-connectors to be used in a transaction. The more is used — the longer route estimation will take, the more complex route might be as a result. If not set, two token-connectors might be used min: 0; max: 3; default: 2
connectorTokens	string	token-connectors can be specified via this parameter. The more is set — the longer route estimation will take. If not set, default token-connectors will be used. If token you want to exchange doesn't have a pool with one of the default token-connectors, this parameter will help find the route; should be the same for a quote and swap e.g.: &connectorTokens=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, 0x6b175474e89094c44da98b954eedeac495271d0f default: list of default token-connectors
gasLimit	integer	maximum amount of gas for a swap; should be the same for a quote and swap default: 11500000; max: 11500000;
mainRouteParts	integer	limit maximum number of main route parts; should be the same for a quote and swap default: 20; max: 50;
parts	integer	limit maximum number of parts each main route part can be split into; should be the same for a quote and swap default: 20; max: 100;

Description of response parameters

Parameter name	Type	Description
fromToken	string	parameters of a token to sell
toToken	string	parameters of a token to buy
fromAmount	string	input amount of fromToken in minimal divisible units
toAmount	string	result amount of toToken in minimal divisible units
protocols	string	route of the trade
gas	string	rough estimated amount of the gas limit for used protocols; do not use gas from the quote method as the gas limit of a transaction
