How do you integrate the Seedance API?

RelayDance exposes an OpenAI-compatible protocol, so existing OpenAI SDK code can be reused. According to the official relaydance.com/docs, 「Set base_url to https://relaydance.com/v1 and keep your OpenAI SDK」. Authentication uses an Authorization: Bearer YOUR_API_KEY header, with keys created in the console. To submit a task, send POST /v1/video/generations with model, prompt, seconds, and metadata, then poll GET /v1/video/generations/{task_id} until status is succeeded or failed. Webhook mode is available by setting metadata.callback_url, so the final state is POSTed to your server. Reference media go in metadata.content[] and are cited in the prompt as @image1 to @imageN. Full details are at https://relaydance.com/docs.

What are the Seedance reference media limits?

RelayDance supports multiple reference inputs per request for guided generation. Each request accepts up to 9 reference images, 3 reference videos, and 3 audio tracks, and generated clips can run up to 15 seconds. Reference media are placed in metadata.content[] and referenced inside the prompt using tags @image1 to @imageN. Metadata fields include ratio, resolution, generate_audio, and callback_url. This structure lets a single call combine text prompts with image, video, and audio references. Combined with pay-as-you-go per-second billing, these limits define the scope of a single video generation task on the platform.
