SeedRouter is a unified API aggregation platform that integrates image, video, language, and audio models into one simple interface. Developers just need to create an API key and top up their balance to call all supported models. There is no need to register separate accounts, manage multiple keys, or handle invoices for each model provider. The platform uses a pay-per-request model, with failed requests not charged, and no subscription fees or minimum monthly charges. It supports OpenAI-compatible endpoints, making it easy to migrate existing code. Video tasks are handled through asynchronous task modes, supporting polling and webhook callbacks. The platform continuously adds new models covering popular series such as GPT, Claude, Gemini, Seedance, and Flux, with transparent pricing suitable for production-grade applications.
