Seedream 5 Flash Layers API for Layer Splitting

Turn one flat png or jpeg into a layered file with POST /api/v1/images/generations and model: seedream-5-flash-layers. ByteDance's Flash tier returns a base image and up to 16 transparent PNG layers, each with a z_index, pixel and normalized bounding boxes, a name and a description, at one price for every output tier.

Input requirements

Ready-to-place layers

The base image has z_index 0; layers ascend from 1. bounding_box.absolute gives [left, top, right, bottom] in base pixels and bounding_box.normalized uses a 0-1000 scale. Layers are always transparent PNG; output_format only sets the base.

Seedream 5 Flash Layers API Pricing

18.87 tokens ($0.3774) per request

The same at 1K, 1.5K, 2K and auto.

Base plus 16 layers

The model decides how many layers to produce, so every request is billed as one base image plus 16 layers, whatever number is returned.

The base image and every layer are priced the same; 17 images at that rate make up the request price.

Refunded on failure

Integrate the Seedream 5 Flash Layers API

1. Create an API key

Generate a key at /keys and send it as Authorization: Bearer <key>.

2. Check the source image

Make sure it is a png or jpeg under 30MB with at least 512x512 pixels in total, served from a public URL.

3. Submit the split

POST {"model": "seedream-5-flash-layers", "image_list": [{"url": "https://…"}], "image_size": "auto"} to /api/v1/images/generations and store the img_uuid.

4. Rebuild the stack

When the job succeeds, sort items by z_index and position each layer with its bounding box. Save the files before links expire 24 hours after completion.

What Developers Build with Seedream 5 Flash Layers

Ad and banner localization

Separate headline text from product and background so each market can replace only the copy layer.

Layered exports for editors

Offer a "make editable" button that turns an uploaded flat image into positioned layers in your canvas editor.

Object libraries

Harvest named, described transparent objects from illustrations to build searchable asset collections.

Depth-based animation

Use z_index order to move foreground and background layers independently for parallax effects.
