Create a free account at RegCheck using the Register form. After email verification, RegCheck provides a test account with 10 free credits. The docs state the REST API uses your RegCheck username as the Basic Auth username and your RegCheck API key as the Basic Auth password; the SOAP/ASMX docs state a username is required for API calls and that username/password are used for the dashboard. Start from the Overview & Authentication and REST API docs, then log in to the account dashboard to view credits and top up.
