RelayDance Documentation

RelayDance is a video generation API. Submit a prompt to https://relaydance.com/v1/video/generations and receive a finished clip: Seedance 2.0, HappyHorse and Grok Imagine models, up to 15 seconds, 480p to 1080p, optional generated audio. Image generation and Grok chat models are included through the same OpenAI-compatible endpoint.

Video tasks are asynchronous: submit, then poll, or set a webhook callback and never poll at all. One API key, one base URL, one balance. Get your API key and start building.
