CoinbaseProExchange.jl

This package provides an unofficial Julia wrapper for the Coinbase Pro REST API. I am in no way affiliated with Coinbase, so use it at your own risk.

Disclaimer: This package is intended to be used ONLY for personal hobby projects which might involve automated trading, building bots or fetching historical data from Coinbase Pro. As with any piece of code, there is a possibility of undiscovered bugs. It goes without saying that you should avoid making large investments using this code. There are professional platforms/services available for doing that.

Remember that cryptocurrency markets are highly volatile and you are likely to lose your investment. Please understand the risks, and do your own research, before you decide to trade in any of the available cryptocurrencies.

How to install?

Press ']' to enter Pkg prompt
add CoinbaseProExchange

Coinbase Pro account

Public endpoints can be accessed without a Coinbase Pro account.

In order to use the private endpoints, you will need to register and create an account on Coinbase. Please note that Coinbase Pro account is separate from Coinbase, but they use the same login credentials. More information about the API can be found here.

API key permissions

You can restrict the functionality of API keys. Before creating the key, you must choose what permissions you would like the key to have. The permissions are:

View - Allows a key read permissions. This includes all GET endpoints.
Transfer - Allows a key to transfer currency on behalf of an account, including deposits and withdraws. Enable with caution - API key transfers WILL BYPASS two-factor authentication.
Trade - Allows a key to enter orders, as well as retrieve trade data. This includes POST /orders and several GET endpoints.

Private endpoints (Coinbase Pro account + API keys are needed)

Obtain your API key, API secret and passphrase from your Coinbase Pro account. Create an object user_data with type UserInfo to store your API data, as shown below:

julia> user_data = UserInfo("YOUR_API_KEY", "YOUR_SECRET", "YOUR_PASSPHRASE")

Use with caution! Market orders are almost always filled immediately.

julia> place_market_order("buy", "ETH-EUR", 15, "quote", user_data)
