Does the API support webhooks?

Not yet. Generation is asynchronous: you request an asset, get an id back immediately, and poll its status endpoint until it's completed (we suggest every 10 seconds — videos typically take 2–6 minutes, descriptions under a minute). The completed response includes the final video URL or description text.

Webhooks are on the roadmap; the polling response shape is designed so they can be added without breaking existing integrations.
