Hailuo

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	7.15	$0.143

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.

string

Body

application/json

model

enum<string>

required

Model name. Must be hailuo_h3.

Available options:

prompt

string

required

Text prompt describing the video. Required. Max 7000 characters.

image_url

string<uri>

Optional 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.

image_end_url

string<uri>

Optional last-frame image. Must be used together with image_url.

resolution

enum<string>

default:2K

Output resolution. This also selects the generation backend and the price — see the pricing table below.

Available options:

480p,

720p,

2K

duration

integer

default:5

Video duration in seconds. Any integer from 5 to 15.

Required range: 5 <= x <= 15

ratio

enum<string>

default:16:9

Aspect ratio. Text-to-video only; ignored when image_url is provided (the ratio then follows the input image).

9:16

custom_callback_url

string<uri>

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.

Example:

"https://your-server.com/goenhance/callback"
