I understand you're having trouble with the documentation link while trying to upgrade from Vapi's free plan.
According to the information I've found, you can upgrade by:
1. Adding payment details
2. Purchasing additional credits
3. Your wallet will then automatically upgrade to pay-as-you-go status
Alternatively, you can switch to credit-based billing by clicking "Switch to Credit Based Billing" on the [billing page](
https://dashboard.vapi.ai/org/billing).
Have you already tried adding payment details in your Vapi dashboard? This would help me understand where exactly you're stuck in the upgrade process.
