CoinMarketCap API Data Retriever

This project retrieves the latest cryptocurrency listings from the CoinMarketCap API and stores the data in a CSV file for further analysis. The script fetches data periodically, making it suitable for tracking cryptocurrency prices over time.

Features

• Connects to the CoinMarketCap API to fetch the latest cryptocurrency data.
• Allows customization of the number of cryptocurrencies retrieved.
• Saves the data into a CSV file, appending new data each time it runs.
• Implements error handling for connection issues and API rate limits.

Requirements

• Python 3.x
• Libraries:
  • requests
  • pandas

You can install the required libraries using pip:

pip install requests pandas

How to Use

1. Clone this repository to your local machine.
2. Open the Python file in your favorite code editor.
3. Replace the placeholder in the api_runner() function with your desired file path and name where you want to save the CSV file.

if not os.path.isfile(r'Enter directory here\File name.csv'):
    df.to_csv(r'Enter directory here\File name.csv', header='column_names')
else:
    df.to_csv(r'Enter directory here\File name.csv', mode='a', header=False)

4. Insert your own CoinMarketCap API key in the headers dictionary.

headers = {
    'Accepts': 'application/json',
    'X-CMC_PRO_API_KEY': 'your_api_key_here',
}

5. Run the script. It will execute the API request every minute for 333 iterations, storing the data in the specified CSV file.

Error Handling

The script includes error handling for connection issues, timeouts, and too many redirects. If an error occurs during the API request, it will print the error message.
