Request contract

Send the model id at the top level. Model-specific controls belong in params.

Key	Type	Required	Default	Description
model	string	Yes	qwen-image-3-pro	Use the qwen-image-3-pro API model id.
prompt	string	Yes	-	Maximum 800 characters for this model.
params	object	Yes	-	Model-specific parameter object. Use the rows below for allowed keys.
client_request_id	string	No	-	Optional client-side id for tracing requests in your system.

Model parameters

Key	Type	Required	Default	Range	Options	Description
resolution	select	Yes	1K	-	1K, 2K	Resolution
image_size	select	No	16:9	-	1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16, 21:9	Image size
output_format	select	No	png	-	png, jpeg	Output format
prompt_extend	select	No	true	-	true, false	Let the model rewrite a simple positive prompt before generation, or turn it off for tighter wording control.
nsfw_checker	select	No	false	-	false, true	Enable the model's optional content filter. No automated filter can guarantee complete coverage.
negative_prompt	text	No	-	-	-	Negative prompt
seed	number	No	1	min 0 / max 2147483647 / step 1	-	Leave it empty for a new random result each time. Reusing the same integer makes it easier to reproduce or fine-tune a previous result. It stays closer only when the prompt and other key settings also remain similar, and it is not a guaranteed 1:1 match.
