Choose square, portrait, landscape, and vertical output formats. -
Resolution control
Generate at1mpfor standard output or4mpfor higher-resolution results. -
Photoreal style preset
Use the optionalphotorealstyle preset when realistic output is preferred. -
Seed support
Use a fixed seed for reproducible results, or-1for a random seed.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text prompt describing the image to generate. Minimum length: 1 character. |
| images | No | Optional reference image. Supports up to 1 image URL. |
| style_id | No | Optional style preset. Supported value: photoreal. Leave unset for no preset. |

| resolution | No | Output resolution: 1mp or 4mp. Default: 1mp. |
| seed | No | Random seed for generation. Use -1 for a random seed. Range: -1–2147483647. Default: -1. |
How to Use
- Write your prompt — Describe the subject, scene, composition, lighting, style, and visual details.
- Add a reference image optional — Provide one image when you want visual guidance.
- Choose style optional — Use
photorealwhen realistic output is needed. - Select aspect ratio — Choose the layout that matches your target format.
- Choose resolution — Use
1mpfor standard generation or4mpfor higher-resolution output. - Set seed optional — Use a fixed seed for reproducible results, or
-1for random generation. - Submit — Generate the final image.
Pricing
Pricing is fixed at $0.04 per image.
| Output | Cost |
|---|---|
| One generated image | $0.04 |
Best Use Cases
- Photoreal image generation — Create realistic images from detailed prompts.
- Marketing visuals — Generate campaign assets, social posts, and promotional imagery.
- Product concepts — Create product scenes, lifestyle visuals, and presentation images.
- Creative ideation — Explore characters, environments, objects, and visual directions.
- Reference-guided generation — Use one reference image to guide composition, subject, or visual style.
Pro Tips
- Use clear prompts with subject, composition, lighting, mood, and background details.
- Use the
photorealstyle preset when realistic output is the main goal. - Add a reference image when you want stronger visual guidance.
- Use
1mpfor faster iteration and4mpwhen higher-resolution output is needed. - Set a fixed
seedwhen comparing prompt or parameter changes. - Choose
9:16for vertical mobile content and16:9for widescreen layouts.
