Veo 3.1 is Google's video generation model. Sosana exposes it via an async API — no Google Cloud setup, single prepaid balance.
Prompt, aspect ratio, first and last frame images, and up to 3 reference images per request.
Typically a few minutes depending on tier and resolution. Use webhook_url to get notified instead of polling.
Prepaid balance, charged per successful render only. Failed renders are retried and never double-billed.
