# SeedRouter
> SeedRouter puts image, video and language models behind a single key. Send one request, get the result, pay only for what was delivered. A request that fails costs nothing.
## Start here
1. Browse [models and current prices](https://seedrouter.ai/models). The model guides below cover published landing pages, not every entry in the live catalog.
2. Create an [API key](https://seedrouter.ai/apikeys) and [add a USD balance](https://seedrouter.ai/billing). Send your key in the Authorization: Bearer header. Keep it in a server-side environment variable.
3. Read the selected model guide before calling it. For GPT Image 2, submit to POST https://api.seedrouter.ai/v1/images/generations, save the returned id, and poll GET https://api.seedrouter.ai/v1/tasks/{id}. The guide includes working examples and the output shape.
Billing uses prepaid USD balance, with no subscription. Unused balance does not expire. Failed requests are not charged. Rates and billing units depend on the model and its channel: Standard model IDs charge one flat price per delivered image, and Official model IDs bill the tokens each render reports. Use current rates rather than remembered prices.
## Choose by task
