Model capabilities

PixVerse V6 Max is the higher-quality version of PixVerse V6. It supports only text-to-video and single-image-to-video, using the same model name, pixverse-v6-max.

Mode	Input	Aspect ratio
Text-to-video	Omit `image_urls`; `prompt` is required	Uses `aspect_ratio`, defaulting to `16:9`
Image-to-video	Supply 1 image in `image_urls`; `prompt` is optional	Follows the input image; `aspect_ratio` has no effect

For first/last frame transitions, multi-image fusion, and video extension, use PixVerse V6.

Request headers

string

required

Bearer authentication: Bearer <token>, where <token> is your APIMart API Key.

Request parameters

string

required

Must be pixverse-v6-max.

string

Describe the content to generate. Required for text-to-video, up to 5000 characters; optional for image-to-video, up to 2048 characters.

string[]

Input image URL list. Image-to-video accepts exactly 1 image; supplying 2 or more returns HTTP 400 synchronously. Omit this field for text-to-video.Images must be publicly accessible over HTTP(S), in JPEG, PNG, or WebP format, under 20 MB, with each side no longer than 10000 pixels.

integer

default:"5"

Output duration in seconds, from 1 to 15; default: 5.

string

default:"540p"

Output resolution: 360p, 540p, 720p, or 1080p; default: 540p.Output uses the upstream model’s native dimensions; the actual returned dimensions are authoritative. Representative observed sizes include 640×360 and 1108×832 (width × height, in pixels).The quality field is also accepted. When both are supplied, resolution takes precedence.

string

Compatibility field for resolution, with the same values as resolution. Used only when resolution is omitted; if both fields are omitted, 540p is used.

string

default:"16:9"

Applies only to text-to-video. Supports 16:9, 9:16, 4:3, 3:4, 1:1, 2:3, 3:2, and 21:9; default: 16:9.Image-to-video always follows the input image’s aspect ratio; this field has no effect.

boolean

default:"false"

Set to true to generate native audio; the default is silent. Generation with audio has a higher per-second rate.Only the top-level audio field in the request body is recognized. metadata.generate_audio_switch does not enable audio or trigger audio-tier billing.

integer

Random seed, from 0 to 2147483647.

Image-to-video example

{
  "model": "pixverse-v6-max",
  "prompt": "Make the subject walk forward slowly",
  "image_urls": ["https://example.com/start.png"],
  "duration": 5,
  "resolution": "1080p"
}

Replace the example URL with a real, publicly accessible image URL. Supply only 1 image; the output aspect ratio follows that image.

Query a task

Replace the task ID in the following request with the task_id returned on submission:

curl --request GET \
  --url 'https://api.apimart.ai/v1/videos/generations/<task_id>' \
  --header 'Authorization: Bearer <token>'

Billing

Cost is the output duration in seconds multiplied by the per-second rate for the selected resolution and audio tier. Audio and silent generation use separate rates; audio costs more per second. If neither resolution nor quality is specified, both output and billing use 540p. Current rates are provided by the model pricing endpoint:

Audio tier	Price field
Silent	The matching resolution price in `resolution_paid_prices`
With audio	The matching `<resolution>-audio` tier in `billing_tier_paid_prices`

Unsupported features and parameter errors

The following requests return HTTP 400 synchronously, without creating a task or charging:

Request	Error message
Includes `extend_from_task_id`	`pixverse-v6-max does not support video extend …; use pixverse-v6 instead`
Includes `img_references`	`pixverse-v6-max does not support multi-image reference …`
Includes `first_frame_image` or `last_frame_image`	`pixverse-v6-max does not support first/last frame transition …`
Supplies 2 or more images in `image_urls`	`pixverse-v6-max image-to-video takes exactly 1 image in image_urls (got N)`
`resolution` is not one of the 4 supported tiers	`invalid resolution …`
`duration` exceeds 15 seconds	`invalid duration …`
Text-to-video `aspect_ratio` is not one of the 8 supported ratios	`invalid aspect_ratio …`
