Simple from the start.
Add some credits.
Choose a credit amount and check out with Stripe. Save a card for next time, or enable automatic top-ups with your own balance threshold and monthly limit. Credits arrive after payment is confirmed.
Make it yours.
Create an API key, choose your model, and make your first request. The playground uses the same balance as the API.
See what you spend.
Each completed request appears in your usage history. Text is charged by tokens; image and video pricing varies by model and output settings.
No mystery math.
If a provider charges $1.00 for a request, your Viki balance is charged $1.20. Model prices shown in the library are estimates before the platform fee.
