hey guys I am building a custom solution where I want to charge my customers on top of their Vapi usage my own fee is there a way to track usage through the api? a webhook that reports on call end with usage of the call would be perfect otherwise, what are possible ways to do this?

Just to confirm you want to track the usage assistant basis?

yes, as long as I can get which assistant costed it'd be cool if not then I can figure something out regardless

so I'd have to make queries every x time?

Yup, that is also possible. You can use the end-of-call-report. We include the cost of that particular call.

oh wow that's awesome

this is awesome! thanks a lot man
