# Seedream 5.0 Pro Layerize Layer Decomposition

> - Asynchronous processing mode, returning a task ID for subsequent queries
- Decompose a single image into multiple independently editable transparent PNG layers
- Each layer includes a name, description, z_index, and bounding_box
- Post-payment billing mode: balance is checked on submission, and settlement is based on actual output after the task is completed


export const apiKeyUrl = 'https://aireiter.com/keys';

## Authorizations

<ParamField header="Authorization" type="string" required>
  All endpoints require Bearer Token authentication.

## Query Task Results

After the task is submitted, use the `POST /api/openapi/query` endpoint to poll the task status. Once the task is completed, the `output` field returns a list of layers.

<RequestExample>
  ```bash cURL theme={null}
  curl --request POST \
    --url https://aireiter.com/api/openapi/query \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json' \
    --data '{
      "out_task_id": "my_task_123456"
    }'
  ```
</RequestExample>

### Query Response - Layer Output Structure

After the task is completed, `output` is an array of layer objects, and each layer contains `url` and `metadata`:

<ResponseField name="output" type="array">
  Layer list, each element is a layer object

  <Expandable title="Layer Object Properties">
    <ResponseField name="url" type="string">
      The transparent PNG image URL for this layer
    </ResponseField>

    <ResponseField name="metadata" type="object">
      Layer metadata

      <Expandable title="Metadata Properties">
        <ResponseField name="kind" type="string">
          Fixed value `"layer"`, indicating that this is a layer output
        </ResponseField>

        <ResponseField name="z_index" type="number">
          Layer index

          * `z_index = 0`: bottom layer (the reconstructed full background image), `bounding_box` is `null`
          * `z_index ≥ 1`: foreground layers, ordered from back to front
        </ResponseField>

        <ResponseField name="bounding_box" type="object | null">
          The position area of the layer in the original image

          The bottom layer (`z_index=0`) is `null`, and the remaining layers return a coordinate object:

          <Expandable title="Bounding Box Properties">
            <ResponseField name="absolute" type="array">
              Absolute pixel coordinates `[x1, y1, x2, y2]`, based on the original image resolution
            </ResponseField>

            <ResponseField name="normalized" type="array">
              Normalized coordinates `[x1, y1, x2, y2]`, ranging from 0–1000
            </ResponseField>
          </Expandable>
        </ResponseField>

        <ResponseField name="name" type="string | null">
          Layer name (for example, `"Sky background"`, `"Moss platform"`)
        </ResponseField>

        <ResponseField name="description" type="string | null">
          Layer description (for example, `"Soft light blue sky with scattered fluffy white clouds"`)
        </ResponseField>
      </Expandable>
    </ResponseField>
  </Expandable>
</ResponseField>

<ResponseField name="credits_used" type="number">
  Actual credits used
</ResponseField>
