# Control The control API is the primary point for querying, structuring, defining and interacting with Engine deployments. The endpoints that it provides enable interaction between drivers operating on an instance and the outside world. The exposed capabilities are dependent on the drivers loaded to an instance. Using this API provides a high level structure for discovering this configuration and interacting with the environment that it connects. All entites—[systems](/api/control/systems.md), [modules](/api/control/modules.md), [dependencies](/api/control/dependencies.md) and [zones](/api/control/zones.md)—provide a model and methods for discovery, management (CRUD) and direct interactions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://engine.place.technology/api/control.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
