# QMK Compiler The QMK Compiler provides an asynchronous API that Web and GUI tools can use to compile arbitrary keymaps for any keyboard supported by [QMK](http://qmk.fm/). The stock keymap template supports all QMK keycodes that do not require supporting C code. Keyboard maintainers can supply their own custom templates to enable more functionality. ## App Developers If you are an app developer interested in using this API in your application you should head over to [Using The API](https://github.com/qmk/qmk_compiler_api/tree/0debc4a22df4515119ac59ba81aed620d9a10fe1/docs/api_docs.html). ## Keyboard Maintainers If you would like to enhance your keyboard's support in the QMK Compiler API head over to the [Keyboard Support](/keyboard-support.md) section. ## Backend Developers If you are interested in working on the API itself you should start by setting up a [Development Environment](/dev-environment-setup.md), then check out [Hacking On The API](/hacking-on-the-api.md). --- # 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://docs.api.qmk.fm/master.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.
