Synchronous until September 10, 2026: the call blocks and returns a single image result with a url (not an array). The image is uploaded and validated, and an image larger than 15MB is rejected with HTTP 400. Credits are charged only on success. Use removeBackground for this dedicated cutout task; editImage can also remove backgrounds via a prompt but is better for broader edits, while createImage and generateWithStyle produce new images rather than process an existing one.

# Remove the background from a single image, returning the subject isolated on a transparent background.

Pass an optional request_id to tag the result so you can retrieve it 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/remove-background`

## Request body

- RemoveBackgroundPayload — Payload for removing the background of an image
  - `image` string, required — URL or base64-encoded image to remove the background from.
  - `crop` boolean — Whether to crop/trim the result to fit the content.
  - `creative_edit` boolean — Higher quality results but the image will not be exactly the same as the input.
  - `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`
