v1.0.0

1.0.0 (2020-04-30)

The first major release of 0x-api.

Features

/swap API

This API faciliates consuming the best-priced liquidity from 0x Mesh and the greater DEX ecosystem through the ERC20BridgeProxy. We use smart order routing to split up your transaction across decentralized exchange networks to be filled with the lowest slippage possible. Follow the Swap Tokens with 0x API guide to see how to use it.

/meta_transaction API

This API makes it easy for integrators to offer their users a meta-transaction trading experience. It provides a superset of the liquidity available via the Swap API (additionally including RFQ liquidity), and also allows integrators to submit the transaction on behalf of their users. This allows them to subsidize the gas cost and protocol fees, removing the need for their users to own Ether.

/sra API

The Standard Relayer API is an API specification that is implemented by several 0x relayers (exchanges), including Radar Relay and Bamboo Relay. It allows you to interact with the liquidity of a certain relayer, including querying and posting to their orderbook. In the 0x API case, it allows you to query and post to 0x Mesh. The 0x API provides a superset of the SRA, and contains functionality that is not strictly part of the spec.
