SeedRouter is a single API for image, video, language and audio models, built for developers shipping AI features into real products. One key reaches 41 models from providers including OpenAI, Anthropic, Google, xAI, ByteDance, Kuaishou, MiniMax, Alibaba, DeepSeek, Kimi, Mistral and Meta, with an OpenAI-compatible endpoint for language models and a task API for longer media jobs.
Billing is pay-per-request against a prepaid USD balance: there is no subscription and no monthly minimum, and a request that fails costs nothing. Each model page lists its live starting price with parameters, a playground and docs, and video jobs return a task id to poll or follow by webhook until the output arrives as a CDN link.
Integration takes four steps — sign up, create a key, point the SDK or HTTP client at the new base URL, and start calling — so an existing OpenAI-based integration can move over without a rewrite. A blog of pricing guides and model walkthroughs documents per-second video rates, token counting and schema quirks. SeedRouter suits product teams that want predictable, auditable model spending across vendors without maintaining separate accounts, keys and invoices for each provider.
