0x API’s /swap endpoint facilitates consuming the best-priced liquidity from the greater DEX ecosystem, including on-chain and off-chain liquidity networks. Under the hood, the API performs three tasks:
- Queries prices from multiple DEXs and market makers and aggregates the liquidity from the queried sources to provide the best price possible. Think of how Google flights aggregates flight prices for a certain time and date to help you find the best price, /swap similarly helps you find the best price across DeFi liquidity sources.
- 0x API’s smart order routing algorithm splits up your transaction across different sources to maximize the overall return on your swap. Read more about smart order routing here.
- API responses are returned in a format that can be easily executed using the Web3 library of your choice
