Fusion notation: v5 uses @pic1/@pic2/@pic3; all other fusion-capable models use @image1…@imageN (mapped positionally to frame_1_path…frame_N_path). Seedance fusion additionally supports @video1 / @video2 for reference videos passed via video_1_path / video_2_path.

Extend, upscale, modify, lipsync

Only native PixVerse models support these endpoints.

v5 family (legacy)

v5 carries legacy-only modes — multi-frame create-transition, lipsync, and fusion with the original @pic1/@pic2/@pic3 notation.

v5 accepts both @image1…@imageN (unified) and the legacy @pic1/@pic2/@pic3 synonyms for backward compatibility.

aspect_ratio is required for t2v and fusion, not accepted for i2v or transition (derived from image).
For kling-o3 / kling-v3: quality: 720p routes to Std, quality: 1080p routes to Pro.
For veo-3.1-standard / veo-3.1-fast: quality: 1080p requires duration: 8.
Seedance fusion is the only path that accepts reference videos. Images go in frame_1_path … frame_9_path; videos go in video_1_path / video_2_path (referenced in the prompt as @video1 / @video2). At least one reference is required. Each reference video must be 2-15s, ≤50 MB, 24-60 fps, ≤6000×6000 px; the sum of all reference video durations must be ≤ 15 sec.

toggle — accept audio: true / false.
always on — audio generated automatically; audio: false is rejected.
rejected — audio parameter is not accepted (content has no audio track or audio is handled internally).

Native PixVerse — extra flags

multi_shot, preview_mode, off_peak_mode, and seed are supported only on native PixVerse models. Third-party models reject them.

Image Models

All image models share the same endpoints: create, list, get, delete.

Model	Qualities	Max Refs	Est. Time
`qwen-image` (default)	720p, 1080p	3	~3s
`nano-banana`	1080p	3	~10s
`nano-banana-2`	512p, 1080p, 1440p, 2160p	9	~30s
`nano-banana-pro`	1080p, 1440p, 2160p	9	~60s

`kling-3.0`	1080p, 1440p	1	~15s
`kling-o3`	1080p, 1440p, 2160p	1	~20s
`gpt-image-2.0`	1080p, 1440p, 2160p	9	~30s

create_count: 1-4 (default 1).
detail_level (gpt-image-2.0 only, required): low, medium, high. Rejected for all other models. Affects credit cost (low = 0.5×, medium = 1×, high = 2× of the per-quality base).

Aspect ratios

Each model accepts its own list. If aspect_ratio is omitted, the default (first column) is used. Passing a value not in the model’s row is rejected with 400.

Models	Default	Accepted `aspect_ratio` values
