API Response
Learn about Totle's API response parameters here.
The response of the swap endpoint is built in an easily understood format with the following sections:

Summary

The summary is a comprehensive breakdown of the transaction where you can get information about the trades, orders, exchanges, fees, etc. in a human-readable format.

Transactions

The transactions section is a list of complete transaction objects that the end user must sign and submit to the Ethereum blockchain. Approval transactions will be prepended to the array. Sign and submit the transactions as they are ordered in the array.
Modification of the transaction objects is strongly discouraged

Expiration

The expiration section contains the expiration block and the estimated expiration timestamp of the Totle swap. Expired transactions will be reverted by the smart contract.
