Text-to-Image
Send the required prompt and omit image_list for pure text-to-image generation.
Reference-Guided Generation
Add 1–10 public image URLs in image_list. Each reference image adds 0.15 token, equal to $0.003.
Validate the request before submission and track the result as an asynchronous image task.
Seedream 5 Pro API Capabilities and Limits
Prompt validation
<code>prompt</code> is required and accepts 1–2,000 characters.
Eight aspect ratios
Set <code>ratio</code> to <code>1:1</code>, <code>4:3</code>, <code>3:4</code>, <code>16:9</code>, <code>9:16</code>, <code>3:2</code>, <code>2:3</code>, or <code>21:9</code>. Omit it to let the model choose from the prompt.
1K or 2K output
Set <code>image_size</code> to <code>1K</code> or <code>2K</code>. The documented default is <code>2K</code>.
Up to 10 references
Pass 1–10 URL objects in <code>image_list</code> for image-to-image guidance, or omit the field for text-to-image.
One image per task
Seedream 5.0 Pro returns a single generated image and does not support sequential grouped-image generation on this route.
Polling or callback completion
Save the returned <code>img_uuid</code>, then poll job detail or receive status changes at a public HTTPS callback URL.
GoEnhance prices the output tier and adds a small charge for each reference image.

Integrate the Seedream 5 Pro API
1
1. Create and protect an API key
Create a key at /keys, send it as bearer authorization, and keep it out of browser code and public logs.
2
2. Build the request
Add the required prompt, choose
1K or 2K, and optionally set a supported aspect ratio. 3
3. Add references only when needed
Include
image_list with 1–10 accessible image URLs for reference guidance; omit it for text-to-image. 4
4. Submit and persist img_uuid
POST to
https://api.goenhance.ai/api/v1/seedream-5-pro and store the returned img_uuid with your internal job record. 5
5. Poll or receive callbacks
Poll
GET https://api.goenhance.ai/api/v1/jobs/detail?img_uuid=..., or provide custom_callback_url for HTTPS status notifications. 6
6. Handle terminal results idempotently
Check HTTP status plus response
code/msg, correct invalid requests before retrying, and prevent duplicate downstream processing.Connect prompt generation, references, async tracking, storage, and review in one image pipeline.
