Introduction

Enable limit orders in your app or take liquidity directly from the 0x Orderbook.

0x API has an Orderbook on the following chains:

  • Ethereum
  • BSC
  • Polygon

In previous versions of 0x API prior to 0x Protocol v4, this functionality was exposed by the "SRA" endpoint. Previous docs: https://github.com/0xProject/standard-relayer-api. Note that 0x Protocol is an open-sourced project that is separate and not maintained by 0x.
