}MiniMax-H3
MiniMax-H3 text-to-video and image-to-video.
Pass image_url for a first frame, optionally with image_end_url for a last frame. For reference-driven generation use the hailuo_h3_refs model instead — first/last frames and reference assets are mutually exclusive.
Pricing — billed per second, by resolution:
| Resolution | Tokens / sec | USD / sec |
|---|---|---|
| 480p | 1.5 | $0.03 |
| 720p | 3 | $0.06 |
| 2K | 4.5 | $0.09 |
All resolutions support 5–15 seconds.
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.

Body
Model name. Must be hailuo_h3.
hailuo_h3 Text prompt describing the video. Required. Max 7000 characters.
7000Optional first-frame image. JPG/PNG/WEBP/HEIC/HEIF, ≤30MB, 256–5760px, aspect ratio 0.4–2.5. When provided, runs image-to-video and the output ratio follows the image.
Optional last-frame image. Must be used together with image_url.
Output resolution. This also selects the generation backend and the price — see the pricing table below.
480p, 720p, 2K Video duration in seconds. Any integer from 5 to 15.
5 <= x <= 15Aspect ratio. Text-to-video only; ignored when image_url is provided (the ratio then follows the input image).
21:9, 16:9, 4:3, 1:1, 3:4, 9:16 Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.
