Costs no credits. status, job_id, job_kind, quote_id, media_url, thumbnail_url, credits_used and error are set by the server when a card runs and are refused here. A per-second model is priced from the card's duration and resolution, so set them before quoting. SIGN-IN REQUIRED: connect this server with OAuth (the host prompts for it), or add an API key header "Authorization: Bearer acd_live_…" created at https://aicontentdrop.com/settings/integrations.
