END-TO-END BILLING — credits per generation, Tinkoff payment confirmed by webhook

Particulars and difficulties

The face has to stay the user’s own

If the model drifts the likeness, the clip stops being about the user — the pipeline holds identity

Every generation costs money

Credits and limits are counted before the run, so the cost of a clip is predictable

Payment confirms itself

Tinkoff acquiring closes by webhook: credits are granted on the fact of payment, not on a redirect

The content goes to social media

Watermarks are applied automatically (ffmpeg, sharp) and the finished file is already in S3
