Swap API (kX)
Overview
This API allows fetching quotes for token swaps and provides transaction data (calldata) for execution if the parameters slippageTolerance, deadline, and recipient are specified. This enables direct interaction with smart contracts.
This API is an aggregator of various providers and selects the best ones.
Currently, the following external providers are supported:
