How to load data from CoinMarketCap to Snowflake destination

Learn how to use Airbyte to synchronize your CoinMarketCap data into Snowflake destination within minutes.

Building your pipeline or Using Airbyte

Airbyte is the only open source solution empowering data teams  to meet all their growing custom business demands in the new AI era.

Building in-house pipelines

Bespoke pipelines are:
  • Inconsistent and inaccurate data
  • Laborious and expensive
  • Brittle and inflexible
Furthermore, you will need to build and maintain Y x Z pipelines with Y sources and Z destinations to cover all your needs.

After Airbyte

Airbyte connections are:
  • Reliable and accurate
  • Extensible and scalable for all your needs
  • Deployed and governed your way
All your pipelines in minutes, however custom they are, thanks to Airbyte’s connector marketplace and AI Connector Builder.

How to Sync to Manually

Step 1: Set Up CoinMarketCap API Access

To start, sign up for a CoinMarketCap account and request an API key. Once you have access, familiarize yourself with the CoinMarketCap API documentation. Determine the specific endpoints you need, such as cryptocurrency listings or quotes, to retrieve the data you want to move to Snowflake.

Step 2: Fetch Data Using Python

Use Python to make HTTP requests to the CoinMarketCap API. Install the `requests` library if you haven't already (`pip install requests`). Write a Python script to authenticate using your API key and fetch the required data. Store this data temporarily in a structured format, such as a JSON file or a Pandas DataFrame.

Step 3: Transform Data into CSV Format

If the data is stored in a Pandas DataFrame, you can convert it to a CSV format using the `to_csv()` method. Ensure that the data is clean and structured according to your Snowflake table schema requirements. This step is crucial for ensuring smooth data loading into Snowflake.

Step 4: Prepare Snowflake Environment

Log into your Snowflake account and configure your environment. Create a new database and a schema if necessary. Define a table structure that matches the schema of your CSV file. Use SQL commands like `CREATE TABLE` to set this up. Make sure the data types and column names are correctly defined.

Step 5: Stage the CSV File in Snowflake

Use Snowflake's internal stage or an external cloud storage (like AWS S3, Azure Blob Storage, or Google Cloud Storage) for staging. For simplicity, use the Snowflake internal stage. Upload your CSV file using the `PUT` command in Snowflake. This will require the SnowSQL command-line tool, which you should configure with your Snowflake credentials.

Step 6: Load Data into Snowflake

Once the CSV file is staged, use the `COPY INTO` command in Snowflake to load the data from the staged file into your designated table. Ensure that any necessary transformations or data type conversions are specified in the `COPY INTO` command to match the table schema.

Step 7: Verify and Clean Up

After loading the data, run queries to verify that the data has been correctly imported into Snowflake. Check for any discrepancies or errors. Once confirmed, clean up by removing any temporary files or data that are not needed, such as the CSV file from the staging area, to maintain a tidy workspace.

By following these steps, you can manually transfer data from CoinMarketCap to Snowflake without relying on third-party connectors or integrations.
