SeedRouter

SeedRouter is a third-party API platform that gives developers one key for image, video, language and audio models from providers such as ByteDance, Kuaishou, OpenAI, Google, Anthropic, xAI, MiniMax and DeepSeek. Its catalogue lists 44 models, including Seedance, Kling, Veo, GPT Image, Nano Banana, Claude, GPT and Gemini, and it is aimed at developers and product teams adding AI generation to their applications.

A developer creates an API key, tops up a USD balance and sends requests. Language models sit behind an OpenAI-compatible endpoint, so existing SDKs work after changing the base URL, and Claude models can also be called with the Anthropic SDK. Image and video jobs are asynchronous: each request returns a task id that can be polled or delivered by webhook. Every model page has parameters, documentation and a playground.

Video models cover text prompts, first and last frames and reference images, with some reaching 4K. Image models handle text prompts, edits with reference images, masked edits and transparent backgrounds. The language API supports chat, reasoning, code generation, tool calls and structured output, and the audio API generates songs, voices and dialogue or separates stems. Solution guides cover product visuals, comics, video production, ecommerce and invoice extraction.

Billing is pay per request with no subscription or monthly minimum, and failed requests are not charged. Balance is bought in USD, never expires, and can be paid by card, PayPal, Alipay, WeChat Pay or crypto, with card top-ups from $20 and a 2% bonus on crypto. Each model lists its own rate, for example Claude Opus 5.5 from $1.20 per million input tokens and Seedance 2.5 from $0.1080 per second.
