Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

PixVerse

PixVerse is the PixVerse route for video extension, turning an existing clip into a production-ready result while keeping the operation distinct from neighboring endpoints. Extend by PixVerse - AI-powered video editing and transformation. Apply style transfer, motion control, lip-sync, and visual effects to existing videos with natural language instructions. The workflow is designed for creators who need the model’s specific transformation to remain visible in the request, so the source, intended change, and finished artifact can be reviewed as one coherent creative decision.

In practical use, this route exposes seed, model, style, video, prompt, duration, resolution, generate_audio_switch to shape the exact deliverable. Those controls let a team preserve the important source constraints, state subject behavior or material treatment precisely, choose supported timing or output characteristics, and reproduce successful settings across alternate takes. The result fits an iterative pipeline: establish the core brief, compare controlled variations, then pass the selected asset into editorial, design, localization, visualization, or publishing work.

Highlights

Seamless clip continuation. Continue a supplied video beyond its current endpoint while carrying forward motion, setting, and visual treatment. This capability belongs to the exact pixverse/extend workflow.
Directed motion. Translate the request into subject movement and camera behavior while maintaining temporal continuity.
Format control. Choose the documented duration and resolution options for the target placement.
Repeatable variation. Use seed and route controls to explore alternates without changing the core shot brief.

When to Use

Scenario	Why it fits
Exact workflow fit	Choose this route when the required deliverable is video extension, rather than a related route with different source media.
Directed creative iteration	Use it when subject, motion, material, speech, framing, or finish should be expressed explicitly and compared across controlled variants.
Existing-asset continuity	Use it when supplied images, video, audio, references, or styles must remain the anchor for the generated result.
Repeatable production	Use it when successful inputs need to be saved and rerun across a campaign, asset set, localization pass, or batch.
Pipeline handoff	Use it when the returned artifact will move into editorial, compositing, visualization, review, storage, or publishing.

Prompt Guide

Start with the source or subject, then describe the intended transformation, movement or behavior, camera and composition, and the desired finish. Keep media URLs reachable, use only fields documented for this exact route, and change one major control at a time when comparing results. For source-led tasks, describe what should change as well as what must remain recognizable.
