# Comfy Router API overview

> How the Comfy Router API works: one route per model ID, with guides for discovery, schemas, queued requests, errors, and billing.

Choose a model, inspect its schema, and call `POST /v2/models/{provider}/{model}`. The route and authentication stay the same across models. Each model accepts its own native request body and returns its own native result.
