OpenRouter describes a concrete way to enforce AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → spending rules: give each workflow a separate API key, then attach a credit limit and an approved-model list. Its routing service can reject requests that exceed those permissions before they reach a model. Separate keys also let operators attribute spending to the responsible workflow. These controls govern model requests; permission to send an email, change a record or perform another tool action must still be enforced by the application. Governance guide
