# Swing Backend - Connection to 1inch API
Swing is missing a lot of traffic from Ethereum. To expedite our launch process and cover more users from Ethereum, we will launch our backend with 1inch API. 

Currently Swing backend is able to fetch price from UniswapV3, UniswapV2, Sushiswap and Dodo. Adding to these dex we need to fetch price and routing from 1inch api. 

1inch API reference: https://docs.1inch.io/api/
You want to focus on these two api: https://docs.1inch.io/api/quote-swap
RPC data provider: Alchemy https://www.alchemy.com/
Web framework: Nest.js
