expand's Aggregated DEX API provides connectivity across the major decentralized exchanges[Uniswapv2,UniswapV3, Sushiswap, Curve, Balancer] available on the Ethereum chain.

Using this API users will be able to fetch the quotes for a swap to make informed decisions and also perform the swaps directly along with methods that support addition and removal of liquidity in a specified pool.
