请求头

x-lifi-api-key

string

The apiKey allows you to authenticate on the API.

请求体

application/json

Object describing what tokens to transfer and how to interact with the destination contracts.

Object defining instructions on how to perform multiple cross-chain/same-chain calls

fromChain

number

必填

The sending chain. Can be the chain id or chain key

fromToken

string

必填

The token that should be transferred. Can be the address or the symbol

fromAddress

string

必填

The wallet that will send the transaction and contains the starting token

toChain

number

必填

The receiving chain. Can be the chain id or chain key

toToken

string

必填

The token required to perform the contract interaction (can be something to stake, donate or to be used as payment)

toAmount

string

必填

The amount of token required by the contract interaction. The LI.FI API will try and generate a quote that guarantees at least that amount on the destination chain.

contractCalls

Root Type for ContractCall · object[]

必填

Show child attributes

toFallbackAddress

string

If the call fails, use this address to send the bridged tokens to. If none is specified, the sending address will be used.

contractOutputsToken

string

Some contract interactions will output a token. This is the case in things like staking. Omit this parameter if no token should be returned to the user.

slippage

number<double>

The maximum allowed slippage for the transaction as a decimal value. 0.005 represents 0.5%.

必填范围: 0 <= x <= 1

integrator

string

A string containing tracking information about the integrator of the API

referrer

string

A string containing tracking information about the referrer of the integrator

allowBridges

string[]

List of bridges that are allowed for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

denyBridges

string[]

List of bridges that are not allowed for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

preferBridges

string[]

List of bridges that should be preferred for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

allowExchanges

string[]

List of exchanges that are allowed for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

denyExchanges

string[]

List of exchanges that are not allowed for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

preferExchanges

string[]

List of exchanges that should be preferred for this transaction. Retrieve the current catalog from the /v1/tools endpoint.

allowDestinationCall

boolean

Whether swaps or other contract calls should be allowed as part of the destination transaction of a bridge transfer. Separate swap transactions on the destination chain are not affected by this flag. By default, parameter is true.

fee

number<double>

The percent of the integrator's fee that is taken from every transaction. The maximum fee amount should be less than 100%.

必填范围: 0 <= x < 1

响应
