Quick start
GET /v1/tasks/{task_id}. Check both status and billing_status. Output URLs are in result.images[].url[]; download them before expiration. A client timeout does not justify a new submission.
Accepted parameters
Exact pixel sizes, layered output and 3K / 4K are not yet exposed. Upstream launch limits can cause HTTP 429 or queues; reduce concurrency and keep polling already submitted tasks.
Billing
Per output: 1K / 1.5K $0.014625**, 2K **$0.02559375. Add $0.00585 for every input reference, including the first. Exact sizes that can cross pixel-price tiers are not exposed.Real outputs
