## Overview

OpenRouter connects multiple model services through one endpoint. Applications select model identifiers and configure providers or fallbacks. Official integration options include HTTP, client SDKs and an Agent SDK with tool loops and state. Models, providers, costs and data terms differ, making it useful for developers switching or comparing services rather than a single foundation model.
