Request notes

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

Request parameters

Wan2.7 R2V uses reference_image/reference_video media and may attach reference_voice. Do not mix this workflow with first_frame/last_frame roles.

Field	Required	Notes
model	Yes	wan2.7-r2v-nsfw
input.prompt	Yes	Describe the scene and reference media using the documented syntax
input.media[]	Yes	At least one reference_image or reference_video
input.media[].reference_voice	No	Public WAV/MP3 URL for voice characteristics
parameters.resolution	No	720P / 1080P
parameters.duration	No	Use the shorter duration limit when a reference video is present
parameters.prompt_extend	No	Set false when this dedicated model contract requires it

Input and output limits

R2V requires at least one reference_image or reference_video, with at most five reference images/videos combined. One first_frame and a reference_voice may be attached; the duration limit is shorter when a reference video is present.

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.

Pricing and billing

This model uses per-second video billing. See the model pricing page for the current customer price, reference list price, and complete specification.

This page documents Modelflare’s public interface; the fields and limits shown here are the current contract.
