coinbase-cli

This is a command-line utility that uses the Coinbase API to trade, deposit and withdraw cryptocurrencies.

On busy days, it has happened that the Coinbase website was down while its underlying API services still worked. This command-line tool is my emergency backup, so that I can trade when everyone else is. Of course, there are many other use cases for a command-line tool such as easily automating trading tasks or inspecting the prices.

Features

• Interactive mode: commands will nicely ask you to input them during command execution
• Non-interactive mode: specify all arguments on the command-line
• Commands (run coinbase help <command> for details):
  • accounts: list your coinbase accounts
  • buy: buy crypto currency with fiat currency
  • buyprice: shows the buy price for a given trade pair
  • paymentmethods: list your coinbase payment methods
  • sell: sell crypto currency for fiat currency
  • sellprice: shows the sell price for a given trade pair
  • spotprice: shows the spot price for a given trade pair
  • time: coinbase server current time
  • withdraw: withdraw fiat currency

Disclaimer

Use this tool at your own risk. Program code can contain bugs - it's open source, so you can check it before you use it.

Installation & Preparation

• Install Node.JS
• Install coinbase-cli by running npm install -g coinbase-cli
• Get your API key and API secret from the Coinbase website
  • Go to Settings - API access and click the 'New API Key' button
  • Ensure you set enough permissions on your key to do what you want to do with the coinbase CLI tool.

Optionally, you can have the CLI tool remember your API key and secret. They will be stored (un-encrypted) in a coinbase.json file in your home directory. If you skip this step, you will have to enter the keys with every command, or pass them on the command-line with every command.

coinbase set api-key "<YOUR_API_KEY>"
coinbase set api-secret "<YOUR_API_SECRET>"

Getting Help

First of all, detailed instructions can be found by executing:

coinbase help
coinbase <command> help

Interactive and Non-interactive mode

For most commands, the tool has two modes: interactive and non-interactive. In interactive mode, you don't provide any command-line arguments except the command you would like to run. The tool then asks you questions on the information it needs.

To use interactive mode, simply type coinbase <command> e.g.:

$ coinbase sell

Done!

Press ESC to cancel while the tool is asking for input. If there is only one option for a choice (e.g. you only have one wallet with a non-zero balance), then the tool won't ask you to choose, it will tell you what the value is.

The other option is to pass all necessary information on the command-line:

coinbase sell --account="a3b02e94-73f8-557a-a553-5329056236542" --payment-method="453ebbdf-9d09-578f-8fec-ecfd7e7fed17" --amount="all"

Troubleshooting

If you get the error request timestamp expired, then your system clock is probably off by more than 30 seconds from the coinbase servers. Run coinbase time to get the time that Coinbase thinks it is.
