# Generate transparent-background images with Ideogram 4.0

`POST /v2/images/generate/ideogram-v4-transparent`

Generate one or more images on a transparent background with
Ideogram 4.0, delivered as PNGs with alpha. The `prompt` accepts
either natural language or a structured Ideogram 4.0 JSON prompt; a
structured prompt is consumed directly and skips magic prompt, except
that its background description is replaced with a
transparent-background directive.

`magic_prompt` controls how a natural-language prompt is prepared:
`AUTO`/`ON` rewrite and expand the prompt before generation, while
`OFF` keeps your wording and only converts the prompt into the
structured format the model consumes.

`output_resolution` selects the output tier (1K to 8K); tiers above
2K are produced by upscaling after generation.

By default the request blocks until the images are ready and returns
them in `data`. Set `async` to true to return immediately after the
request is accepted, then poll for completion and results with
`GET /v1/generations/{generation_id}` using the returned
`generation_id`.

## Request body

- GenerateImageIdeogramV4TransparentRequest
  - `prompt` string, required — The prompt to generate images from. Accepts either natural language or a structured Ideogram 4.0 JSON prompt; the server detects which was supplied. A structured JSON prompt is consumed by the model directly and skips magic prompt, except that its background description is replaced with a transparent-background directive.
  - `magic_prompt` 'AUTO' | 'ON' | 'OFF' — Determine if MagicPrompt should be used in generating the request or not.
  - `seed` integer — Random seed. Set for reproducible generation.
  - `num_images` integer — The number of images to generate.
  - `aspect_ratio` 'AUTO' | '1x4' | '1x3' | '1x2' | '9x16' | '10x16' | '2x3' | '3x4' | '4x5' | '1x1' | '5x4' | '4x3' | '3x2' | '16x10' | '16x9' | '2x1' | '3x1' | '4x1' — The aspect ratio for an Ideogram 4.0 magic prompt. `AUTO` lets the model select the most suitable ratio from the prompt; any other value pins the ratio. The non-AUTO values are the buckets the 4.0 model supports.
  - `output_resolution` '1K' | '2K' | '4K' | '8K' — The output resolution tier for the generated images. Tiers are total-pixel budgets matching a square of the named size (for example, `8K` delivers at most 8192x8192 total pixels); wide and tall aspect ratios keep the same pixel budget, so a single dimension may exceed the named size. Defaults to 1K.
  - `rendering_speed` 'TURBO' | 'DEFAULT' | 'QUALITY' — The rendering speed to use.
  - `enable_copyright_detection` boolean, nullable — Optional. Opt this request into post-generation copyright detection. Adds detection latency; flagged images come back with `is_image_safe: false`.
  - `async` boolean — When false (the default), the request blocks until the images are ready and returns them in `data`. When true, the request returns as soon as it is accepted; poll for completion and results with `GET /v1/generations/{generation_id}` using the returned `generation_id`.

## Response `200`

The generated images (synchronous requests), or an acknowledgement to poll with `GET /v1/generations/{generation_id}` (`async` requests).

- GenerateImageIdeogramV4TransparentResponse — Response returned by `POST /v2/images/generate/ideogram-v4-transparent`. Synchronous requests (the default) include the generated images in `data`. Requests with `async` set to true omit `data`; poll for completion and results with `GET /v1/generations/{generation_id}` using the returned `generation_id`. The seed reports the value the request resolved to when the caller left it unset.
  - `generation_id` string, required — URL-safe base64 ID of the accepted generation. Accepted by the `GET /v1/generations/{generation_id}` polling endpoint.
  - `data` GeneratedImageObject[] — The generated images, in generation order. Present only for synchronous requests (`async` omitted or false).
    - `url` string, uri, nullable — The direct link to the generated image. Empty when the image did not pass safety checks.
    - `prompt` string, required — The final prompt the image was generated from.
    - `resolution` string, required — The resolution of the generated image, formatted as "WIDTHxHEIGHT".
    - `is_image_safe` boolean, required — Whether the image passed safety checks. If false, `url` is empty.
    - `seed` integer, required — Random seed. Set for reproducible generation.
  - `seed` integer, required — Random seed. Set for reproducible generation.

## Other responses

- `400` — Invalid input provided.
- `401` — Unauthorized.
- `402` — Insufficient credits or quota.
- `422` — The prompt did not pass safety checks.
- `429` — Too many requests.
- `500` — Internal server error.
- `503` — The endpoint is temporarily unavailable.
