Pass `image_list` to edit reference images (1-3), or omit it for pure text-to-image. Always returns a single image. **Pricing** — output tier plus a surcharge per reference image: | What | Tokens | USD | |---|---|---| | Output, 1K | 2.43 | $0.049 | | Output, 2K | 4.85 | $0.097 | | Each reference image | 0.19 | $0.0039 | Example: 2K with 3 reference images = 4.85 + 3 x 0.19 = 5.42 tokens. `image_size` decides the price tier. Two cases are billed differently from what you send: `ratio: auto` is always billed at the 2K rate (the model picks the resolution, so it cannot be known up front), and `1:8` / `8:1` are always billed at the 1K rate (they cannot be produced above that tier). For a cheaper flat rate use `/api/v1/qwen-image-3`, where both tiers cost 1.75 tokens. Returns an `img_uuid`; poll GET /api/v1/jobs/detail (or use `custom_callback_url`) to get the generated image. ## OpenAPI ````yaml POST /api/v1/qwen-image-3-pro openapi: 3.1.0 info: title: GoEnhance API description: '' version: 1.0.0 servers: - url: https://api.goenhance.ai security: - bearerAuth: [] tags: - name: Basic - name: Video2Video paths: /api/v1/qwen-image-3-pro: post: tags: - ImageAPI summary: Qwen-Image 3.0 Pro description: >- Qwen-Image 3.0 Pro text-to-image and image editing in a single endpoint.

Defaults to auto, which lets the model pick the resolution from the prompt.

See the pricing note above — it also decides what you pay. image_list: type: array items: type: object properties: url: type: string format: uri required: - url description: >- Optional reference images for image editing, [{"url": "https://..."}]. Up to 3 images, each under 10MB. The array order is the order the prompt refers to them in. Each one adds 0.19 tokens. minItems: 1 maxItems: 3 negative_prompt: type: string maxLength: 2000 description: Optional. Describes what should not appear in the image. seed: type: integer minimum: 0 maximum: 2147483647 description: Optional. Fixing the seed makes results more reproducible. prompt_extend_mode: type: string enum: - direct - agent default: direct description: >- Prompt rewriting mode. `agent` rewrites more thoroughly but is text-to-image only — sending it together with image_list is rejected. custom_callback_url: type: string format: uri description: >- Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt. example: https://your-server.com/goenhance/callback required: - prompt example: prompt: >- Replace her outfit with a tailored charcoal blazer, keep the face unchanged ratio: '3:4' image_size: 2K image_list: - url: https://example.com/portrait.png responses: '200': description: '' content: application/json: schema: type: object properties: code: type: integer msg: type: string data: type: object properties: img_uuid: type: string required: - img_uuid required: - code - msg - data examples: '1': summary: Success value: code: 0 msg: Success data: img_uuid: c12b656c-747a-44fd-9c80-add79b0c52d5 '2': summary: Insufficient tokens value: code: 100 msg: tokens is not enough headers: {} '401': description: '' content: application/json: schema: type: object properties: code: type: integer msg: type: string required: - code - msg headers: {} deprecated: false security: [] components: {} ````
