SeedRouter is an API gateway that puts models from several providers behind a single key. Its model list spans language models such as GPT-6 and Kimi K3, image and video models including Dreamina Seedance, and audio models, each with its own page showing parameters, a playground and documentation.
Billing works from a prepaid USD balance. A buyer tops up an amount, pays by card and spends the balance across every model; the pricing page says one dollar paid is one dollar of balance, there is no monthly minimum, and a request that fails costs nothing. Each model card shows its own starting price, such as per-million-token rates for language models.
The language models can be called with the OpenAI or Anthropic SDKs, so an existing integration can point at SeedRouter by changing the base URL and key. The site also runs a blog and docs, and lists an integration walkthrough in four steps.
The service fits developers who want to test or switch between providers without managing a separate account and key for each one. Teams with strict data-handling needs should read the privacy and docs pages first, because requests pass through a third party before reaching the model provider.
