Connect to Alchemy Data in RazorSQL

The CData JDBC Driver for Alchemy enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Alchemy using wizards in RazorSQL.

Create a JDBC Data Source for Alchemy Data

1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
2. In the Connection Wizard that appears, set the following properties:
   • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
   • Driver Class: Set the driver class to cdata.jdbc.api.APIDriver.
   • Username: Enter the username. (This property can also be set in the JDBC URL.)
   • Password: Enter the password. (This property can also be set in the JDBC URL.)

   • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:api: and is followed by a semicolon-separated list of connection properties.

     Start by setting the Profile connection property to the location of the Alchemy Profile on disk (e.g. C:\profiles\Alchemy.apip). Next, set the ProfileSettings connection property to the connection string for Alchemy (see below).

     Alchemy API Profile Settings

     Alchemy uses API key authentication. The API key is supplied in the request URL path. To obtain an API key:

     1. Sign in to your Alchemy account at https://dashboard.alchemy.com.
     2. Open an existing app or create a new one.
     3. Copy the app's API key from the API Key dialog.

     After obtaining your API key, set the following connection properties:

     • AuthScheme: Set this to APIKey.
     • Network: Optional. The blockchain network slug for NFT API requests (for example, eth-mainnet, base-mainnet, polygon-mainnet). Defaults to eth-mainnet.

     Set the following in the ProfileSettings connection property:

     • APIKey: Set this to your Alchemy app API key.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Alchemy JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     
     java -jar cdata.jdbc.api.jar
     

     Fill in the connection properties and copy the connection string to the clipboard.

     

     A typical JDBC URL is the following:

     jdbc:api:Profile=C:\profiles\Alchemy.apip;AuthScheme=APIKey;Network=eth-mainnet;ProfileSettings='APIKey=your_api_key';

Query Alchemy Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
