AI Video API — Best Model for Every Job
Live500+ video models, one API keyMuapi's AI video API gives you one REST integration for generation and editing jobs: quality, value, uncensored generation, video editing, motion control, and open-weights models. Pick the best model per request instead of committing to one vendor's trade-offs.
Seedance 2.5
Multimodal reference inputs, multi-scene continuity, and synchronized audio generated with the video in one pass.
PixVerse V6
Resolution-based pricing from low-cost previews to 1080p output with generated audio.
Seedance 2.5 Spicy
Seedance 2.5 quality with a more permissive safety profile for content the standard endpoint may decline.
Runway Aleph
Transform an existing clip's visual style or scene with a natural-language instruction while preserving motion.
Kling v3.0 Pro Motion Control
Directed camera and performance transfer for more precise subject movement than a generic text-to-video prompt.
MiniMax H3 Open
Open-weights video generation with native stereo audio and 480p/768p duration tiers.
Veo 3.1
High-end scene consistency and prompt understanding for cinematic text-to-video output.
Gemini Omni Video Edit
Edit visuals and audio together from a natural-language instruction, including scene, season, and dialogue changes.
What Is an AI Video API?
An AI video API turns a text prompt, an image, or an existing video clip into new video output through a REST endpoint. No local GPU, self-hosted model, or separate vendor integration is required. Different models lead on different jobs: raw quality, price, editing, directed motion, or open-weights control.
Muapi exposes 500+ video models through the same request-and-poll flow: one API key, pay-per-generation pricing, and the freedom to switch models per request.
Key Capabilities
Text, Image, and Video Input
Generate from a prompt or image, or transform an existing video clip with the model-specific fields supported by the selected endpoint.
One Key, Every Model
Switch between Seedance, PixVerse, Kling, Runway, MiniMax, LTX-2, Vidu, Gemini, and other video models without a new vendor account or SDK.
Directed Camera and Motion Control
Use motion-control models and multimodal references to guide camera paths, performance transfer, and subject movement.
Video-to-Video Editing
Restyle, extend, reframe, or transform an existing clip from a prompt instead of generating a new shot from scratch.
Open-Weights Options
Use open-weights models such as MiniMax H3 Open and LTX-2 Pro through hosted endpoints without managing GPU infrastructure.
Pay Per Generation
There is no subscription or minimum commitment; pricing is determined by the selected model, resolution, duration, and options.

Prices and supported parameters vary by model. Check each model's Playground schema before submitting production requests.
How to Call the AI Video API
- Choose a model. Select a model by quality, price, editing, motion control, or open-weights requirements.
- Host your inputs. Upload images or video through POST /api/v1/upload_file, or use publicly reachable URLs.
- Submit the request. Call POST /api/v1/{model-slug} with a prompt and the input, duration, resolution, or reference fields supported by that model.
- Poll and persist the result. Check GET /api/v1/predictions/{request_id}/result until status is completed, then download the video to your own storage.

What is the best AI video API model?
It depends on the job. Seedance 2.5 is a strong overall choice, PixVerse V6 is optimized for value, Seedance 2.5 Spicy is the more permissive tier, Gemini Omni Video Edit and Runway Aleph edit existing clips, and Kling v3.0 Pro Motion Control targets directed movement.
Can I use one API key for every video model?
Yes. The video catalog uses one Muapi API key and the same submit-and-poll pattern across generation and editing endpoints.
How much does AI video generation cost?
Prices range from about $0.033 per second for low-cost PixVerse output to premium per-generation tiers. The exact cost depends on the model and its options.
Can I edit an existing video instead of generating from scratch?
Yes. Video-to-video models such as Gemini Omni Video Edit and Runway Aleph take a source video and a prompt, then return a transformed result.
What is the difference between closed and open-weights video models?
Open-weights models publish their weights and can have different licensing and output-rights terms from closed models. Check the selected model's terms for your use case.
Can I get AI Video API access right now?
Yes. Sign up at muapi.ai, create an API key from your dashboard, and start calling a video endpoint immediately without a waitlist.
