Request notes

Wan commonly uses input and parameters; frame-guided and reference-media modes must not be mixed.

Request parameters

Wan3.0 uses input.prompt or input.media with output controls in parameters. Media may represent frames, references, audio, files, or webpages.

Input and output limits

Supported scope

This page covers Modelflare model generation and editing calls. Search or map enrichment, voice management, and element-library management are resource APIs outside this public model-call surface and are not required request fields.
