# coinmarketcap
|
||||
> A Python class for the API on [CoinMarketCap](https://coinmarketcap.com)
|
||||
|
||||
## Requirements
|
||||
* [Python](https://www.python.org/downloads/) *(**Note:** This script was developed to be used with the latest version of Python)*
|
||||
|
||||
## 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...
|
||||
```
