How Do I Use the Seedance 2.5 API?
A production-safe Seedance 2.5 API workflow: choose a route, submit a prediction, poll results, and handle failures.
Overview
Use the Seedance 2.5 API by selecting the correct WaveSpeedAI model route, sending a prediction request with your prompt and supported inputs, saving the returned prediction id, and polling for the finished result. For example, a text-to-video workflow uses the bytedance/seedance-2.5/text-to-video route, while image-to-video and edit workflows use their own routes.
Start with the endpoint schema, not a copied prompt. Check required fields, allowed aspect ratios, duration range, resolution options, and audio or reference controls. If your product needs images, videos, or audio as references, label them clearly in your app and in the prompt so the model knows what each asset should control.
Build the backend as a job system. Validate inputs before submission, persist the request body, prediction id, account, estimated cost, and user-facing status. Poll with increasing intervals for long jobs, stop on terminal states, and log the error body so support can explain why a generation failed.
In production, wrap Seedance 2.5 behind a provider boundary. That keeps your app stable if you later switch from text-to-video to image-to-video, add a fallback model, or change retry rules. WaveSpeedAI gives you the API surface; your system still owns validation, storage, moderation, and budget limits.
