-> :warning: **@0x/asset-swapper has been deprecated!** The `asset-swapper` code has been moved to [0x-api](https://github.com/0xProject/0x-api). Please do not open a PR with `asset-swapper` changes.
-
-## @0x/asset-swapper
-
-Convenience package for swapping assets represented on the Ethereum blockchain using 0x. The package helps to perform all the off-chain computations to execute a marketBuy or marketSell function execution with 0x exchange contracts, or 0x extension contracts. Given some liquidity (0x signed orders), it helps estimate the cost of buying or selling a certain asset (giving a range) and then provide varying consumable outputs to execute the buy or sell.
-
-Asset-swapper integrates with the [Standard Relayer API](https://github.com/0xProject/standard-relayer-api)(in the future Mesh as well) and takes care of sourcing liquidity, order-pruning, and order-validation. The final result is a library that tells you what assets are available, provides a quote based on specified assets, and provide varying consumable metadata that can be used both on-chain in smart contracts or off-chain through web3 to swap a desired amount of ERC20 for another ERC20 asset.
-
-## Installation
-
-```bash
-yarn add @0x/asset-swapper
