An AI gateway sits on the path between agents and models, tools, and other agents. It is where identity, spend, and policy get enforced once instead of in every client.

This hub collects the definition, the cost controls, and the working demos. Security findings that happen to use a gateway live in [Agent Security](/agent-security/). Identity work lives in [Agent Identity](/agent-identity/).
