1. API Description

Domain name for API request: vod.intl.tencentcloudapi.com.

This API is used to generate AIGC images. The default limit is 1 concurrent processing. API calls will incur actual fees. Refer to the VOD AIGC image generation billing documentation. The settlement mode for the feature is pay-as-you-go. For daily billing customers, usage on the day is billed on the second day. For monthly settlement customers, the usage fees of the previous month are billed on the 1st of the next month.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    Prompt No String

    Prompt for image generation. This parameter is required when FileInfos is empty.
    NegativePrompt No String

    Prompt content to prevent the model from image generation.
    EnhancePrompt No String

    Whether to optimize Prompt content automatically. When Enabled, the passed-in Prompt will be optimized automatically to enhance generation quality. Valid values:

    		•
    Seed No Integer

    Random seed of the model.
    SessionId No String

    Identifier for deduplication. If a request with the same identifier has been sent within the past three days, an error is returned for the current request. The maximum length is 50 characters. If this is not specified or left empty, deduplication is not performed.
    SessionContext No String

    Source context. This is used to pass user request information. The audio and video quality revival complete callback returns the value of this field. The maximum length is 1000 characters.

    Reserved field, used for special purposes.

    • Hunyuan 3.0

      • Supports free resolution width and height settings. Both width and height are within the pixel range of [512, 2048], and the product of width and height must be ≤ 1024x1024 pixels. Example: {"AdditionalParameters": "{"size":"728x1024"}"}

    • OG

      • Supports free resolution width and height settings:
        • The calculated pixel size must be divisible by 16
        • The total pixels must be at least 655,360 and should not exceed 8,294,400
        • Example: {"AdditionalParameters": "{"size":"728x1024"}"}
      • Supports setting a transparent layer:
        • Example: {"AdditionalParameters": "{"background":"transparent"}"}

    • Kling

      • Supports setting image expansion parameters. Example: {"AdditionalParameters":"{"down_expansion_ratio":0.2,"left_expansion_ratio":0.3,"right_expansion_ratio":0.4,"up_expansion_ratio":0.1}}
        • Common constraints:
          • Value range: [0, 2];
          • The overall area of the new image should not exceed 3 times that of the original image;
          • Forward prompt content can be input through the Prompt field.
          • Example description:
            • up_expansion_ratio: expands upward, calculated as a multiple of the original image height. If the original image height is 20 and the parameter value is 0.1, the distance from the top edge of the original image to the top edge of the new image is 20 × 0.1 = 2. This region is the expansion range.
            • down_expansion_ratio: expands downward, calculated as a multiple of the original image height. If the original image height is 20 and the parameter value is 0.2, the distance from the bottom edge of the original image to the bottom edge of the new image is 20 × 0.2 = 4. This region is the expansion range.
            • left_expansion_ratio: expands to the left, calculated as a multiple of the original image width. If the original image width is 30 and the parameter value is 0.3, the distance from the left edge of the original image to the left edge of the new image is 30 × 0.3 = 9. This region is the expansion range.
            • right_expansion_ratio: expands to the right, calculated as a multiple of the original image width. If the original image width is 30 and the parameter value is 0.4, the distance from the right edge of the original image to the right edge of the new image is 30 × 0.4 = 12. This region is the expansion range.

    3. Output Parameters

    Parameter Name Type Description
    TaskId String

    Task ID.
    RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
