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	wan2.6, wan2.6-flash
prompt	string	Yes	1–1,500 characters; describe motion, camera work, and dialogue.
seconds	integer	Yes	5, 10, 15; with reference media only 5 or 10.
resolution	string	No	720p / 1080p. Pixapi default: 1080p.
n	integer	No	Default 1; only integer 1 is supported.
image	string / string[]	No	One public first-frame URL; JPEG/PNG/WebP/BMP. Flash requires this or metadata.reference_urls. Do not combine both modes.
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
aspect_ratio	string	16:9, 9:16, 1:1, 4:3, 3:4. Default 16:9; image-to-video follows the input image ratio.
negative_prompt	string	Content to exclude; at most 500 characters.
seed	integer	Random seed, 0–2147483647; omitted means random. The same seed does not guarantee identical output.
prompt_extend	boolean	Rewrite and expand the prompt for generation; default true.
watermark	boolean	Add a visible AI watermark. Default false.
audio	boolean	Default on. Only wan2.6-flash permits false; wan2.6 rejects silent output.
audio_url	string	Public WAV/MP3 URL for synchronized audio. Input audio should be at least as long as the requested video; longer audio is trimmed. Not supported in reference mode.
shot_type	string	single (default) or multi. Generation from text/first frame requires prompt_extend=true for this control.
metadata	object	Only reference_urls: 1–5 public image/video URLs, at most 3 videos (MP4/MOV). Do not combine with image, audio_url, or prompt_extend; seconds must be 5 or 10. Use character1, character2 in prompt order.
