No. You buy credits, then top up whenever you need to. There is no automatic renewal.

Which models are available?+

The catalog brings together OpenAI and Anthropic models. Active models and their real prices appear in the Pricing section.

How do I get an API key?+

Create an account, top up your balance, then generate a key from the dashboard. The complete key is shown only when it is created.

How do bonuses work?+
