How to load data from CoinGecko Coins to MySQL Destination

Begin by setting up a MySQL database where you can store the data. You will need to create a database and a table with appropriate columns to match the data structure you expect to receive from CoinGecko. For example, a table named `crypto_data` with columns like `id`, `name`, `symbol`, and `price` can be created. Use a MySQL client like MySQL Workbench or the command line to execute SQL commands.

Make sure you have Python installed on your system. You will need to install the `requests` library to interact with the CoinGecko API and `mysql-connector-python` to connect to your MySQL database. You can install these via pip:
```bash
pip install requests mysql-connector-python
```

Use Python to make a request to the CoinGecko API. Write a script that sends an HTTP GET request to CoinGecko's endpoint for fetching cryptocurrency data. For example:
```python
import requests

response = requests.get('https://api.coingecko.com/api/v3/coins/markets', params={'vs_currency': 'usd'})
data = response.json()
```

Once the data is fetched, process it to fit the structure of your MySQL table. This involves iterating over the JSON data and extracting relevant fields. Ensure data types match those defined in your database:
```python
processed_data = [
(coin['id'], coin['name'], coin['symbol'], coin['current_price'])
for coin in data
]
```

Establish a connection to your MySQL database using the `mysql-connector-python` library. You’ll need your database credentials like host, user, password, and database name:
```python
import mysql.connector

connection = mysql.connector.connect(
host='localhost',
user='your_username',
password='your_password',
database='your_database_name'
)
cursor = connection.cursor()
```

Insert the processed data into your MySQL table. Use prepared statements to insert the data to avoid SQL injection and enhance performance:
```python
insert_query = """
INSERT INTO crypto_data (id, name, symbol, price) VALUES (%s, %s, %s, %s)
"""

cursor.executemany(insert_query, processed_data)
connection.commit()
```

After successfully inserting the data, close the cursor and database connection to free up resources:
```python
cursor.close()
connection.close()
```

This guide provides a straightforward approach to moving data from CoinGecko's API into a MySQL database using Python, without relying on third-party connectors or integrations. Make sure to handle exceptions and errors as needed in the actual implementation.
