All fields

Send these fields in input. A field the table does not list is refused with HTTP 422 invalid_input.

content needs at least one text, image or video item.
Every image, video and audio item in content names its role.
Input limits: up to 9 images, 3 videos and 3 audio items in content, with no limit on the total. Each video and audio item runs 2 to 15 seconds. Videos add up to at most 15 seconds, and audio to at most 15 seconds. Lengths are checked before the task is created when the file can be measured (422 input_duration_out_of_range). Task type and drafts are not supported.
Image pixel size and aspect ratio, and video resolution and frame rate, are not checked when the request is made: the model checks them when the task runs, and a file it refuses usually fails the task with input_media_invalid (otherwise generation_failed); the task is not charged.
first_frame and last_frame images (at most one each) cannot be combined with reference images, videos or audio, and a last_frame needs a first_frame.
Audio items need at least one image or video in content.
Prompt text must not contain inline --flag parameters.
