Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Hailuo 2.3 Pro Text to Video Generate short video scenes with Hailuo 2.3 Pro, with 1080p output and optional prompt refinement for written scene concepts. ## Available Models * **minimax/hailuo-2.3/pro/text-to-video** - Generate video scenes from text prompts. ## Duration Options * **6 seconds** - Set `duration` as an integer. Optional. Default: **6 seconds**. ## Key Features * Generate video scenes from text prompts. * This model ID fixes the output resolution to `1080p`. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place all workflow parameters, including output options, inside `input`. Send only the input fields supported by this workflow. JSON types are validated without converting strings to numbers or booleans; `prompt` must be a string and fractional durations are rejected. Unsupported `input` fields are rejected before credits are deducted. ### Prompt * `prompt`: Required. Describe the scene and desired motion. Length: **1-5,000 characters**. * The value must not be blank when supplied. ### Resolution * `resolution`: Optional. Accepted values: `1080p`. Default: `1080p`. ### Prompt Optimizer * `prompt_optimizer`: Optional. Control automatic prompt optimization. Use `true` or `false`. Omit this field to leave it unspecified upstream; no API default is imposed. ## Billing Factors Billed per video using the Pro model tier. This endpoint fixes output resolution to `1080p` and duration to `6` seconds. Prompt optimization (`prompt_optimizer`) does not change the charge. Credits are deducted on submission and refunded if the task fails. ## OpenAPI ````yaml api-manual/video-series/minimax-hailuo-2-3-pro-text-to-video.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Hailuo 2.3 Pro Text to Video description: >- Generate short video scenes with Hailuo 2.3 Pro, with 1080p output and optional prompt refinement for written scene concepts. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Hailuo 2.3 Pro Text to Video description: >- Send only the fields shown for this workflow.
