Python-CoinMarketCap API Wrapper

This is a non-official (but working) Python package to wrap the CoinMarketCap API. With this you can monitor and watch the crypto market.

• Read the official API documentation
• For the pro version, get an API Key on the Developper Portal
• Be sure to replace the API Key in sample code with your own.

Installation

Via pip

• pip install python-coinmarketcap

/!\ Don't confuse this with the coinmarketcap package.

Example

from coinmarketcapapi import CoinMarketCapAPI

cmc = CoinMarketCapAPI()
  
rep = cmc.cryptocurrency_info(symbol='BTC') # See methods below

print(rep.data)                 # Whole repsonse payload
print(rep.data["BTC"]["logo"])  # Some data in response
print(rep.credit_count)         # API credits
print(rep.total_elapsed)        # Request time in ms
# ...

CoinMarketCapAPI

Synopsis

CoinMarketCapAPI(api_key=None, [debug=False, logger=None, sandbox=False, version='v1'])

• debug: set verbosity.
• sandbox: In case of default sandbox API key changes, see Issue #1.
• logger: you can give a custom logger.
• version: set the version in the URL, for futures version.

Methods

You have to pass to the following methods the parameters detailed in the official documentation.

Additionnal Parameters

• api_version (str): if given, will fetch the given version of the endpoint (default is equal to the given version in the CoinMarketCapAPI instance wich is actually v1). As mentioned in the list above, some endpoints are "v2" by default.

Example

Assuming you want to get informations about bitcoin. First, read the documentation of the corresponding cryptocurrency_info endpoint.

• You can pass the symbol parameter like : cmc.cryptocurrency_info(symbol='BTC')
• or with the slug parameter : cmc.cryptocurrency_info(slug='bitcoin')

You can switch easly in the sandbox mode without giving an API key or by setting it to None :

• cmc = CoinMarketCapAPI() # You are in sandbox environnement

You can enable a debuging mode, just set debug to True to main class:

cmc = CoinMarketCapAPI(debug=True)
cmc.cryptocurrency_info(symbol='BTC')

This will produce this output :

2019-04-06 16:03:04,716 root         DEBUG    GET SANDBOX 'v1/cryptocurrency/info'
PARAMETERS: {'symbol': 'BTC'}
2019-04-06 16:03:05,004 root         DEBUG    RESPONSE: 288ms OK: {u'BTC': {u'category': u'coin', u'name': u'Bitcoin', u'tags': [u'mineable'], u'symbol': u'BTC', u'id': 1, [...]}

Optionnaly, you can pass (on-the-fly) a specific version of an endpoint by given the api_version keyword argument directly to a method:

cmc.cryptocurrency_listings_latest(..., api_version="v1.1")

Response

Synopsis

You get results of the API in a Response instance.

Property

Corresponding to standards and conventions:

• data (dict): will give you the result.
• status (dict): the status object always included for both successful calls and failures.
• credit_count (int): the number of credits this call utilized.
• elapsed (int): the number of milliseconds it took to process the request to the server.
• total_elapsed (int): the total number of milliseconds it took to process the request.
• timesamp (str): current time on the server when the call was executed.
• error_code (str | None): In case of an error has been raised, this property will give you the status error code.
• error_message (str | None): In case of an error has been raised, this property will give details about error.
• error (bool): True if an error has been raised.

Example

r = cmc.cryptocurrency_info(symbol='BTC')
print(repr(r.status))
print(repr(r.data))
print(repr(r.credit_count))

CoinMarketCapAPIError

Synopsis

If API returns an error, CoinMarketCapAPI will raise a CoinMarketCapAPIError.

Property

• rep (Response | None): will give you a Response instance or None if request failed for an other reason than a server error.

Example

from coinmarketcapapi import CoinMarketCapAPI, CoinMarketCapAPIError

cmc = CoinMarketCapAPI('{YOUR_API_KEY}') # Pro environnement
# cmc = CoinMarketCapAPI() # Sandbox environnement

try:
  r = cmc.cryptocurrency_info(symbol='BTC')
except CoinMarketCapAPIError as e:
  r = e.rep
  print(repr(r.error))
  print(repr(r.status))
  print(repr(r.data))
