currently the way to view your balance is on the AI Gateway tab of the Vercel dashboard. will look into enabling this programmatically if this is something you'd like!

Yes, that would be very helpful, especially for a production application and not just for testing and development.

I know various AI APIs already provide this, like Openrouter.

@w3bdesign we now have a credits endpoint to fetch credit info programmatically. here's the docs. let us know if you want more data returned by the endpoint or if you have any other general feedback!

Just a minor bug report:

You should probably set a reasonable maximum length for the custom amount here, because I can enter any number, and it will fill up the entire space.
