Sample outputwan2.7-image-nsfwPOST /v1/images/generations

Parameters: size=1536x1024n=1watermark=false

Prompt: A sunlit poolside deck at midday. A blonde woman with a curvy full figure, wearing a white bikini and tortoiseshell glasses, lies on her front on a striped towel right at the edge of the frame, propped up on both forearms with her lower legs bent up behind her. She is looking straight down the lens over the top of her glasses with a relaxed smile. Shot on a 35mm lens held low and very close to her, so she fills the frame from shoulders to raised feet, shallow depth of field with the pool and loungers soft behind. Warm midday sun from the left, bright bounce off the pale deck, glossy skin and damp hair at the temples. Editorial swimwear photography, natural skin texture, film grain, no text.

This sample is deliberately mild. It is not the content limit of this model ID.

Authentication and endpoint

Use a Modelflare API key with https://modelflare.dev/v1. The gateway entry point is POST /v1/images/generations.

HTTP

Authorization: Bearer YOUR_MODELFLARE_API_KEY

Generate an image

bash

curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "wan2.7-image-nsfw",
    "prompt": "A white cat runs through a neon-lit street in the rain",

  }'

Request notes

OpenAI-compatible image models use prompt, n, size, and quality; use editing only when the official page documents it.

Request parameters

Wan2.7 Image / Pro uses the synchronous Images API. Use the flat OpenAI-compatible shape for simple calls; use input.messages plus parameters for multi-image, region editing, and sequential generation. Pro text-to-image supports up to 4K outside sequential mode; the standard model supports up to 2K.

Field	Required	Notes
model	Yes	wan2.7-image-nsfw
prompt	Yes	Generation or editing instruction
image	No	Single image URL/Base64; use input.messages for up to 9 images
input.messages	No	Nested messages for multi-image, region editing, and sequential generation
size	No	1K / 2K; Pro non-sequential text-to-image also supports 4K
n	No	1–4 for ordinary generation; 1–12 for sequential generation; billed per successful image
thinking_mode	No	Thinking mode when no image is supplied
watermark	No	Whether to add a watermark
parameters.prompt_extend	No	Prompt expansion, default true; use the Direct NSFW row and set false for special-content requests
parameters.bbox_list	No	Interactive editing region boxes
parameters.enable_sequential	No	Enable sequential generation
parameters.color_palette	No	3–10 HEX colors with percentages totaling 100%

Response and input limits

Use the flat shape for simple calls; use input.messages and parameters for multi-image, region editing, and sequential generation. Up to 9 input images are supported, each under 20 MB, 240–8,000 px per edge, with a 1:8 to 8:1 aspect ratio. Ordinary output count is 1–4 and sequential output count is 1–12; Pro text-to-image supports 4K outside sequential mode, while other combinations top out at 2K.

Documented workflow examples

Wan2.7 Image supports both a flat shape and the nested input.messages/parameters shape; use the nested shape for multi-image, region editing, and sequential generation.

Multi-image editing

curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \

      {"image": "https://example.com/person.png"},
      {"image": "https://example.com/background.png"},
      {"text": "将图 1 中的人物放入图 2 的场景中"}
    ]}], "parameters": {"size": "2K", "n": 1, "prompt_extend": true}}
  }'

Interactive region editing

bash

curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \

      {"image": "https://example.com/room.png"},
      {"text": "将选中区域的花瓶替换成红玫瑰"}
    ]}], "parameters": {"size": "2K", "n": 1, "bbox_list": [[[420, 280, 760, 720]]]}}
  }'

Sequential image group

bash

curl https://modelflare.dev/v1/images/generations \
  -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "wan2.7-image-nsfw", "input": {"messages": [{"role": "user", "content": [{"text": "生成四张角色一致的季节分镜"}]}]},
