REST API ReferenceEndpointsTools

Generate image

Generate an image from a text prompt, optionally guided by one or more reference images. When reference images are provided, the prompt describes the desired transformation. VideoGen automatically routes each request to the most effective state-of-the-art image model for your prompt, reference images, and quality tier, so you don’t pick a model.

Authentication

Request

This endpoint expects an object.
promptstringRequired
Text prompt describing the image to generate. When reference images are provided, the prompt describes the desired transformation.
qualityenumRequiredDefaults to STANDARD

Image generation quality tier. LOW is fastest; HIGH is slowest and highest quality.

imageFileIdslist of stringsOptional

Optional file ids of reference images (e.g. ["vg_file_..."]). Upload files first via POST /v1/files/upload, then pass the returned ids here. Maximum 4 images. When provided, the model uses these as guidance for generation.

aspectRatioobjectOptional

Aspect ratio for the generated image. Defaults to 16:9 when omitted.

watermarkModeenumOptionalDefaults to AUTO

Controls whether the VideoGen watermark is applied to the output. AUTO applies the watermark unless you have the Production API add-on. VIDEO_GEN always applies it. NONE removes the watermark — requires the Production API add-on; returns an error if you don’t have it.

numResultsintegerOptional1-100Defaults to 1
Number of output results to generate. Defaults to 1.
isOutputTemporarybooleanOptionalDefaults to false

When true, generated files are temporary. Temporary files are guaranteed to be available for 24 hours, after which they may be archived at any time. Temporary files are not analyzed (no description, transcript, or embedding will be generated), so they will not appear in search results. Defaults to false.

Response

Execution accepted; poll until complete.

toolExecutionIdstring

Execution id (e.g. vg_tool_...).
