When Google introduced Veo 3, it marked a turning point in AI video by showing that models could generate not only visuals but also synchronized audio. For the first time, developers had access to clips where speech, sound effects, and music aligned naturally with the generated imagery.
The Wan 2.5 model follows this same direction. In addition to text-to-video and image-to-video generation, it can produce native audio that matches lip movements and scene dynamics. For developers, these capabilities are exposed through the Wan 2.5 API, which is available on Kie.ai. The API is accessible on Kie.ai, which provides documentation and integration support to help developers integrate the tool into various workflows.

Key Features of Wan 2.5 AI Video API
Native Audio Generation with Perfect Visual Sync
The Wan 2.5 AI API excels in producing videos with native audio-visual synchronization, generating human voices, ambient sound effects, and background music that align precisely with on-screen actions and lip movements. This reduces reliance on external audio editing and may benefit use cases such as tutorials or storytelling projects.
Audio-Driven Content with Consistent Voice Tones
With the Wan 2.5 Preview API, creators can upload a pre-recorded audio track to drive video generation, ensuring consistent voice tones across scenes. The AI utilizes this reference to generate content with matching audio characteristics, built to support high-concurrency workloads, which can be relevant for real-time or large-scale video applications.
High-Definition 1080p Video with Fluid Motion
The Wan 2.5 text-to-video API delivers stunning 1080p videos at 24 frames per second, offering crisp visuals and consistent frame rates for smooth, lifelike motion. Enhanced motion dynamics ensure fluid transitions and realistic physics, designed for scenarios where visual clarity and motion consistency are essential, such as fast-moving or detailed scenes.
Advanced Cinematic Camera Control
The Wan AI Video API provides advanced camera controls, enabling smooth pans, zooms, tilts, and dolly shots with professional-grade precision. Creators can dictate cinematic movements to craft visually engaging scenes, from sweeping landscape shots to focused character close-ups, allowing creators to define cinematic movements for more controlled and visually engaging outputs.
Wan 2.5 API Pricing Compared: Kie.ai vs. Fal.ai
When adopting any video generation API, cost becomes a practical consideration. Kie.ai sets Wan 2.5 API pricing at $0.06 per second for 720p output and about $0.10 per second for 1080p output. This model enables developers to calculate expenses based on video length and resolution easily.
By comparison, Fal.ai offers $0.05 per second for 480p, $0.10 for 720p, and $0.15 for 1080p. At lower resolutions, the differences are minor, but for high-definition output, Kie.ai provides 1080p generation at a lower rate.

It provides resources to assist developers during the integration process.
Reliable Performance with High Concurrency
The Wan AI Video API on Kie.ai is built for stability, supporting high-concurrency workloads without compromising speed or quality. This design supports high-concurrency workloads, which can be applied in scenarios such as real-time content generation or large-scale video production.
Free Trial for New Users
A free trial is available for the Wan 2.5 Preview API, enabling developers to test its features before committing to paid usage. The free trial enables developers to test features such as audio-visual sync and cinematic controls before deciding on further use.
Getting Started with Kie.ai’s Wan 2.5 API
Obtain Wan 2.5 AI API Key from Kie.ai
Users can register on Kie.ai to obtain an API key, which is required for authentication and access.
Configure Video Generation Settings
Once you have your Wan 2.5 API key, define your video parameters, such as resolution (720p or 1080p), duration, and input type—whether using the Wan 2.5 text-to-video API for text prompts or the image-to-video API for static visuals. These settings allow you to tailor the output to your project’s creative needs with precision.
Monitor Task Progress in Real Time
After submitting your video generation request, Kie.ai provides a task ID to track progress. The Wan 2.5 Preview API offers real-time status updates, such as “waiting” or “generating,” enabling you to manage workflows efficiently and ensure the timely delivery of your video content.
Retrieve and Utilize Your Video Output
When your video is complete, Kie.ai delivers a direct link to the final output. For automated workflows, you can set up a callback URL to receive notifications. The process provides direct links or callback options, allowing outputs to be integrated into applications or workflows.
Wrapping Up: Wan 2.5 API on Kie.ai for Video Generation
The Wan 2.5 API shows how AI video models have evolved from demos to practical tools for developers. With text-to-video, image-to-video, audio sync, and HD output, it provides a solid foundation for generating short-form videos.
By making the API available on Kie.ai, developers gain access to clear documentation, predictable pricing, and infrastructure capable of handling higher workloads. For teams building products, testing new features, or exploring automation, the Wan 2.5 API on Kie.ai offers a practical entry point into AI video generation, offering an alternative to traditional production processes that may require more manual effort.
