SeedRouter

SeedRouter puts LLM, image, video and audio models behind one API key. Pay per request — failed requests cost nothing. OpenAI-compatible, built for production.

SeedRouter is a single API gateway for every AI model your product needs. One key. One request shape. One dashboard. One invoice.

Instead of managing separate accounts with OpenAI, Anthropic, Google, ByteDance, DeepSeek, and every other model vendor — each with their own SDK, authentication, billing, and rate limits — SeedRouter puts all of them behind a single endpoint. You load a balance, create one API key, and call any model on the platform with the same request structure.

The billing model is equally clean: you pay per request, only when the result is delivered. A request that fails costs nothing. There is no monthly minimum, no subscription, and no mystery wrapping around the models you are calling.

SeedRouter currently supports 18 live models across image generation, video generation, language, and audio — covering model families from Anthropic, OpenAI, Google, ByteDance, DeepSeek, Moonshot AI, and more.
