curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-5-0-pro-nsfw",

    "size": "1024x1024", "n": 1
  }'

Request notes

Seedream uses the Images API request shape; the four generation/layer-decomposition prices for seedream-5-0-pro-nsfw are listed below.

Request parameters

Seedream uses the Images API. Normal generation/editing uses prompt, image, and size; seedream-5-0-pro-nsfw also exposes layer_decomposition with the four quoted rows below.

Field	Required	Notes
`model`	Yes	`seedream-5-0-pro-nsfw`
`prompt`	Conditional	Generation, editing, or layer-decomposition instruction
`image`	Conditional	One or more reference images (model-dependent limit)
`size`	No	`1K` / `1.5K` / `2K` or documented pixel dimensions
`response_format`	No	`url` / `b64_json`
`output_format`	No	`png` / `jpeg`
`watermark`	No	Whether to add a watermark
`sequential_image_generation`	No	`auto` or `disabled` where supported
`layer_decomposition`	No	Pro only; split a source into background and transparent layers

Response and input limits

URL responses are temporary and should be saved promptly; decode b64_json on the client. Pro layer_decomposition returns a background plus transparent layers and may include layer order, names, and bounds.

Four price specifications

Operation	Size condition	Official list price	Customer price
`generation`	≤1.5K	$0.045	$0.04095
`generation`	>1.5K	$0.09	$0.0819
`layer_decomposition`	≤1.5K	$0.0225	$0.020475
`layer_decomposition`	>1.5K	$0.045	$0.04095

Layer-decomposition example (only seedream-5-0-pro-nsfw)

curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-5-0-pro-nsfw",
    "image": "https://example.com/source.png",
    "layer_decomposition": true,
    "size": "1.5K",
    "response_format": "url",
    "output_format": "png"
  }'

The data[] response contains the background and extracted transparent layers; billing follows the matching layer_decomposition row below.

Supported scope

This page covers Modelflare model generation and editing calls. Search or map enrichment, voice management, and element-library management are resource APIs outside this public model-call surface and are not required request fields.

Pricing and billing

This model uses per-image billing. See the model pricing page for the current customer price, reference list price, and complete specification.
