Async is the intended integration pattern: pass `async: true` and the call returns 202 with a job id - poll `GET /assets/jobs/{id}` (`getApiJob` in MCP), honouring poll_after_ms or long-polling with wait=30, until status is succeeded, whose result field is exactly the response documented for this operation.

# Generate new images that match the visual style of a reference image: supply a style_image (URL or base64) plus a text prompt describing what to create and an image_type (defaults to sprite).

Pass an optional request_id to tag the results so you can retrieve them later via \`GET /assets/images/results\`. Requires an API key (user scope). Async is the intended integration pattern: pass \`async: true\` and the call returns 202 with a job id - poll \`GET /assets/jobs/{id}\` (\`getApiJob\` in MCP), honouring poll_after_ms or long-polling with wait=30, until status is succeeded, whose result field is exactly the response documented for this operation.

`POST /assets/image/style`

## Request body

- GenerateWithStylePayload — Payload for generating new content while maintaining the visual style of a reference image
  - `style_image` string, required — URL or base64-encoded reference image whose visual style should be matched.
  - `prompt` string, required — Text description of what to generate (e.g., "a warrior character", "a forest background", "a treasure chest").
  - `image_type` string, required — What kind of image to generate.
  - `n` number — Number of variations to generate (1-4).
  - `augment_prompt` boolean — Augment the prompt behind the scenes. Disable to have more control.
  - `request_id` string — Optional client-provided identifier, unique per request. Re-sending the same request_id returns the existing job instead of generating again. Also usable with the results endpoint.
  - `async` boolean — When true, return 202 immediately with a job id instead of waiting for the result. Poll GET /assets/jobs/{id}. Defaults to false (synchronous).

## Response `200`

Success

- ImageResult[]
  - `url` string
  - `request_id` string
  - `created_at` integer

## Other responses

- `202` — Accepted - the generation was queued (async: true, or a synchronous call still running after 15 minutes). Poll GET /assets/jobs/{id}.
- `400` — Error

## Changes

- **2026-08-30** `a8a0b85d1839` — 1 info
  - added the success response with the status `202`
