Use the getRoutes function to fetch routes/quotes from the Keygate API. Here is a simple example of how to request routes to bridge 10 USDC on Optimism to the maximum amount of ckUSDC on Internet Computer Protocol 
import { getRoutes, RouteResponse } from '@keygate/sdk'

const routes: RouteResponse[] = await getRoutes({
  inputAmount: '10000000', // 10 USDC
  fromChainId: 10, // Optimism
  fromToken: '0x0b2c639c533813f4aa9d7837caf62653d097ff85', // USDC on Optimism
  toChainId: 121171651099711, // Internet Computer Protocol
  toToken: '5okwm-giaaa-aaaar-qbn6a-cai' // osUSDC on Internet Computer Protocol
})
