# Advertisement Resizer

`POST /v2/tool/ad-resizer`

Reframes the source creative to the exact requested ad resolution,
regenerating the layout so text and key elements stay legible at the
target size.

The request is processed asynchronously. Poll
`GET /v1/generations/{generation_id}` with the returned `generation_id`
until the generation is completed or failed. The completed generation
reports the exact amount billed for the request in
`usage_cost_usd_micros`.

Supply the source creative as either an `AssetIdentifier` reference
(`image_asset_identifier`) or the raw image bytes directly (`image`,
multipart requests only). Provide exactly one of the two forms;
supplying both, or neither, is rejected with a 400.

## Request body

- AdResizerRequest — Supply the source creative as either an `AssetIdentifier` reference or (multipart requests only) raw image bytes; provide exactly one of the two forms. Supplying both, or neither, is rejected with a 400.
  - `image_asset_identifier` AssetIdentifier — An identifier for an ideogram asset.
    - `asset_type` 'ASSET' | 'CANVAS_ASSET' | 'LAYERED_ASSET' | 'RESPONSE' | 'UPLOAD', required
    - `asset_id` string, required
  - `image` string, binary — The source creative to reframe (max size 25MB), as raw bytes; only JPEG, PNG, and WEBP formats are supported. Multipart requests only. Provide exactly one of `image_asset_identifier` or `image`.
  - `resolution` '300x250' | '336x280' | '300x600' | '1080x1080' | '1080x1350' | '1080x1920' | '1920x1080' | '728x90' | '160x600' | '970x250' | '320x50' | '300x50' | '320x100' | '1800x900' | '2400x2400' | '1200x3500' | '2880x2880' | '2560x3200' | '3200x2560' | '2448x3264' | '3264x2448' | '2336x3504' | '3504x2336' | '2240x3584' | '3584x2240' | '2160x3840' | '3840x2160' | '1920x3840' | '3840x1920' | '1280x3840' | '3840x1280', required — Target ad resolution, formatted as `WIDTHxHEIGHT`. Must be one of the supported ad resolutions listed above; any other value is rejected with a 400. Each returned image has exactly these pixel dimensions.
  - `prompt` string — Optional edit instruction to apply while reframing, for example "remove the logo" or "put the price bottom-right".
  - `quality` 'VERY_LOW' | 'LOW' | 'MEDIUM' | 'HIGH' — The generation quality level. Higher levels may use more inference steps or additional prompt processing.
  - `num_images` integer — The number of reframed variations to generate.
  - `private` boolean — If true, the user is requesting private generation. If omitted, this defaults to the user's plan entitlement. Enterprise generations are always private.
  - `webhook_url` string, uri — HTTPS URL that Ideogram delivers the generated result to. Ideogram sends a JSON POST to this URL once all images for the request have finished generating. The body mirrors the synchronous generate response: `request_id`, `created`, and a `data` array containing every generated image (`url`, `prompt`, `resolution`, `seed`, `is_image_safe`). Each delivery is signed with Ed25519 and verifiable against the public keys at `https://api.ideogram.ai/v1/.well-known/jwks.json`. Must be HTTPS; private and loopback hosts and the cloud metadata service are rejected.

## Response `200`

Ad resize accepted for asynchronous processing.

- AdResizerResponse — Acknowledgement that the ad resize was accepted. Poll `GET /v1/generations/{generation_id}` for status and results.
  - `generation_id` string, required — URL-safe base64 ID accepted by the generation polling endpoint.

## Other responses

- `400` — Invalid input provided.
- `401` — Unauthorized.
- `402` — Insufficient credits or quota.
- `403` — Not authorized to resize an ad.
- `404` — Source asset not found.
- `422` — The prompt was rejected by safety checks.
- `429` — Too many requests.
