# coinmarketcap > A Python class for the API on [CoinMarketCap](https://coinmarketcap.com) ## Requirements * [Python](https://www.python.org/downloads/) ## API Documentation - [CoinMarketCap API Documentation](https://coinmarketcap.com/api/documentation/v1/) ## Information In order to use the CoinMarketCap API, you will need an API key which you can sign up for one [here](https://pro.coinmarketcap.com/signup/). Data from the API will be cached for 5 minutes at a time (that is how long it takes CoinMarketCap to refresh their data) this way you will not get rate limited. The class has only 2 main functions, one for global data and one for ticker data. ## Example ```python from coinmarketcap import CoinMarketCap CMC = CoinMarketCap('API_KEY_HERE') global_data = CMC._global() # Global data example print('Cryptocurrencies : ' + str(global_data['cryptocurrencies'])) print('Exchanges : ' + str(global_data['exchanges'])) print('BTC Dominance : ' + str(global_data['btc_dominance'])) print('ETH Dominance : ' + str(global_data['eth_dominance'])) print('Market Cap : ' + str(global_data['market_cap'])) print('Volume : ' + str(global_data['volume'])) ticker_data = CMC._ticker() # Ticker data example for item in ticker_data: print('ID : ' + item) print('Name : ' + ticker_data[item]['name']) print('Symbol : ' + ticker_data[item]['symbol']) print('Slug : ' + ticker_data[item]['slug']) print('Rank : ' + str(ticker_data[item]['rank'])) print('Price : ' + str(ticker_data[item]['price'])) print('1h Percent : ' + str(ticker_data[item]['percent']['1h'])) print('24h Percent : ' + str(ticker_data[item]['percent']['24h'])) print('7d Percent : ' + str(ticker_data[item]['percent']['7d'])) print('Volume : ' + str(ticker_data[item]['volume'])) print('Market Cap : ' + str(ticker_data[item]['market_cap'])) input('') # Press enter to continue... ``` ___ ###### Mirrors [acid.vegas](https://git.acid.vegas/coinmarketcap) • [GitHub](https://github.com/acidvegas/coinmarketcap) • [GitLab](https://gitlab.com/acidvegas/coinmarketcap) • [SuperNETs](https://git.supernets.org/acidvegas/coinmarketcap)
