That preview used the same render pipeline as the API. In production, put a signed URL in your <head> and the image re-renders whenever a parameter changes — new price, new episode, new title. The signature keeps the API key private, and CDN cache hits never touch your quota.
No card required. Failed renders never bill, and nothing auto-charges.
