Generate from Dashboard

When you log in, the initial screen is the Docs page. Click Dashboard at the top of the screen, select API keys from the left sidebar, and click the Create new secret key button to generate an API key.

​

Click the icon in the top right, select Billing from the left sidebar, and Click Add payment details to register a card and add credits.
