Questions about pricing
Can I use MediCrab without paying anything?
Yes. Use free hosted models, your own API key, or a Codex or Claude subscription you already have.
What happens when a subscription limit is reached?
Subscription limits reset on their own schedule. While a limit is reached, MediCrab switches to a model on your account to keep going and says so in the report.
Does my own API key go to MediCrab?
No. Requests go from the app to the endpoint you configured and are billed by that provider.
I need more credits.
Email [email protected]. Meanwhile, free models, your own API, and your subscription keep working.
