Request fields

Send the common fields at the top level. Put the model-specific controls listed below inside providerOptions.

Field	Type	Required	Description
model	string	Yes	wan2.7-image, wan2.7-image-pro. Case-sensitive model ID.
prompt	string	Yes	Describe the subject, composition, style, and requested edits. Pixapi keeps the first 2,000 characters; provide a non-empty prompt for both generation and editing.
n	integer	No	Default 1. Standard mode 1–4; sequential mode 1–9 on Pixapi (maximum 12).
size	string	No	Use pixel dimensions WIDTHxHEIGHT, for example 1024x1024.
image	string / string[]	For edits	Public HTTP(S) image URL or URL array; required on /images/edits. Pixapi accepts up to 4 references. JPEG/PNG/WebP/BMP; each 240–8000 pixels, ≤ 20 MB. Editing follows the last image ratio and is limited to 2K.
providerOptions	object	No	Model-specific options; see the table below.

providerOptions

All fields in this table are nested inside providerOptions, not alongside model.

Field	Type	Description
nsfw_check	boolean	Optional prompt/image moderation; default false.
negative_prompt	string	Describe content to exclude.
watermark	boolean	Add a visible AI watermark. Default false.
seed	integer	Random seed, 0–2147483647; omitted means random. The same seed does not guarantee identical output.
thinking_mode	boolean	Default true; only effective for text-to-image without sequential mode.
enable_sequential	boolean	Default false. Generate a coherent image series; disables thinking_mode and color_palette, and caps Pro output at 2K.
bbox_list	array	One array per input image; up to two [x1,y1,x2,y2] pixel boxes per image. Use [] for an image without a region.
color_palette	object[]	3–10 {hex,ratio} entries; ratios are percentage strings and must total 100.00%. Not effective in sequential mode.

Input rules

Use size pixels for output dimensions. Pro text-to-image supports up to 4K; standard, editing, and sequential output up to 2K.
