The official Python library for the Coinbase API V2.
Important: this library currently targets the API V2, and the OAuth client requires V2 permissions (i.e. wallet:accounts:read).
If you're still using the API V1, please use the old version of this library.
- Near-100% test coverage.
- Support for both API Key + Secret and OAuth 2 authentication.
- Convenient methods for making calls to the API - packs JSON for you!
- Automatic parsing of API responses into relevant Python objects.
- All objects have tab-completable methods and attributes when using IPython.
coinbase is available on PYPI.
Install with pip:
pip install coinbaseor with easy_install:
easy_install coinbaseThe library is currently tested against Python versions 2.6.9, 2.7.10, 3.2, 3.3.6, and 3.4.3.
The first thing you'll need to do is sign up with Coinbase.
If you're writing code for your own Coinbase account, enable an API key.
Next, create a Client object for interacting with the API:
from coinbase.wallet.client import Client
client = Client(api_key, api_secret)If you're writing code that will act on behalf of another user, start by creating a new OAuth 2 application from the API settings page.
You will need to do some work to obtain OAuth credentials for your users; while outside the scope of this document, please refer to our OAuth 2 flow documentation.
Once you have these credentials (an access_token and refresh_token), create a client:
from coinbase.wallet.client import OAuthClient
client = OAuthClient(access_token, refresh_token)Both the Client and OAuthClient support all of the same API calls.
We've included some examples below, but in general the library has Python classes for each of the objects described in our REST API documentation.
These classes each have methods for making the relevant API calls; for instance, coinbase.wallet.model.Order.refund maps to the "refund order" API endpoint.
The docstring of each method in the code references the endpoint it implements.
Every method supports the passing of arbitrary parameters via keyword. These keyword arguments will be sent directly to the relevant endpoint. If a required parameter is not supplied, the relevant error will be raised.
Each API method returns an APIObject (a subclass of dict) representing the JSON response from the API, with some niceties like pretty-printing and attr-style item access (response.foo is equivalent to response['foo']). All of the models are dumpable with JSON:
user = client.get_current_user()
user_as_json_string = json.dumps(user)And, when the response data is parsed into Python objects, the appropriate APIObject subclasses will be used automatically.
See the code in coinbase.wallet.model for all of the relevant classes, or the examples below.
API methods that return lists of objects (for instance, client.get_accounts() return APIObject instances with nice wrappers around the data of the response body. These objects support direct indexing and slicing of the list referenced by data.
accounts = client.get_accounts()
assert isinstance(accounts.data, list)
assert accounts[0] is accounts.data[0]
assert len(accounts[::]) == len(accounts.data)But, the APIObject is not actually a list (it's a subclass of dict) so you cannot iterate through the items of data directly.
Simple slicing and index access are provided to make common uses easier, but to access the actual list you must reference the data attribute.
All the objects returned by API methods are subclasses of the APIObject and support being "refreshed" from the server.
This will update their attributes and all nested data by making a fresh GET request to the relevant API endpoint:
accounts = client.get_accounts()
# Create a new account via the web UI
accounts.refresh()
# Now, the new account is present in the listThe API V2 will return relevant *warnings* along with the response data.
In a successful API response, any warnings will be present as a list on the returned APIObject:
accounts = client.get_accounts()
assert (accounts.warnings is None) or isinstance(accounts.warnings, list)All warning messages will also be alerted using the Python stdlib warnings module.
Several of the API V2 endpoints are paginated.
By default, only the first page of data is returned. All pagination data will be present under the pagination attribute of the returned APIObject:
accounts = client.get_accounts()
assert (accounts.pagination is None) or isinstance(accounts.pagination, dict)All errors occuring during interaction with the API will be raised as exceptions.
These exceptions will be subclasses of coinbase.wallet.error.CoinbaseError.
When the error involves an API request and/or response, the error will be a subclass of coinbase.error.APIError, and include request and response attributes with more information about the failed interaction.
For full details of error responses, please refer to the relevant API documentation.

The OAuth client provides a few extra methods to refresh and revoke the access token.
# exchange the current access_token and refresh_token for a new pair
oauth_client.refresh()This method will update the values stored in the client and return a dict containing information from the token endpoint so that you can update your records.
# revoke the current access_token and refresh_token
oauth_client.revoke()Protip: You can test OAuth2 authentication easily with Developer Access Tokens which can be created in your OAuth2 application settings. These are short lived tokens which authenticate but don't require full OAuth2 handshake to obtain.
Sending money may require the user to supply a 2FA token in certain situations.
If this is the case, a TwoFactorRequiredError will be raised:
from coinbase.wallet.client import Client
from coinbase.wallet.error import TwoFactorRequiredError
client = Client(api_key, api_secret)
account = client.get_primary_account()
try:
tx = account.send_money(to='[email protected]', amount='1', currency='BTC')
except TwoFactorRequiredError:
# Show 2FA dialog to user and collect 2FA token
# two_factor_token = ...
# Re-try call with the `two_factor_token` parameter
tx = account.send_money(to='[email protected]', amount='1', currency='BTC', two_factor_token="123456")Verify notification authenticity
client.verify_callback(request.body, request.META['CB-SIGNATURE']) # true/falseThis is not intended to provide complete documentation of the API. For more details, please refer to the official documentation. For more information on the included models and abstractions, please read the code – we've done our best to make it clean, commented, and understandable.

# Install the requirements
pip install -r requirements.txt
pip install -r test-requirements.txt
# Run the tests for your current version of Python
make testsIf you'd also like to generate an HTML coverage report (useful for figuring out which lines of code are actually being tested), make sure the requirements are installed and then run:
make coverageWe use tox to run the test suite against multiple versions of Python.
You can install tox with pip or easy_install:
pip install tox
easy_install toxTox requires the appropriate Python interpreters to run the tests in different environments. We recommend using pyenv for this. Once you've installed the appropriate interpreters, running the tests in every environment is simple:
tox
