+"Public API" of Airflow
+=======================
+
+The Public API of Apache Airflow is a set of programmatic interfaces that allow developers to interact
+with and access certain features of the Apache Airflow system. This can include operations such as
+creating and managing DAGs (directed acyclic graphs), managing tasks and their dependencies,
+and extending Airflow capabilities by writing new Executors, Plugins, Operators and Providers. The
+public API of Apache Airflow can be useful for building custom tools and integrations with other systems,
+as well as for automating certain aspects of the Airflow workflow.
+
+In general, the public API is an important part of the Airflow ecosystem and can be a powerful tool for users
+and developers who want to extend the functionality of the system.
+
+What kind of APIs are Public in Apache Airflow?
+===============================================
+
+Apache Airflow has a number of different public APIs that allow developers to interact with various
+aspects of the system. Some examples of the types of public APIs exposed as Python objects
+that are available in Apache Airflow include:
+
+* :doc:`DAG <concepts/dags>`_ (Directed Acyclic Graph) APIs, which allow developers to create, manage,
+ and access DAGs in Airflow.
+* :doc:`Task <concepts/tasks>`_ APIs, which provide access to information about individual tasks within
+ a DAG, such as their dependencies and execution status.
+* :doc:`Operator <concepts/operators>`_ APIs, which allows the developers to write their custom Operators.
+* :doc:`Decorators <howto/create-custom-decorator>`_ APIs, which allows the developers to write their
+ custom decorators to make it easier to write :doc:`TaskFlow <tutorial/taskflow>`_ DAGs.
+* :doc:`Secret Managers <security/secrets>`_ APIs, which allows the developers to write their custom
+ Secret Managers to safely access credentials and other secret configuration of their workflows.
+* :doc:`Connection management <concepts/connections>`_ APIs, which allow developers to manage
+ connections to external systems
+* :doc:`XCom <concepts/xcoms>`_, which allow developers to manage cross-task communication within Airflow.
+* :doc:`Variables <concepts/variables>`_, which allow developers to manage variables within Airflow.
+* :doc:`Executors <executor/index>`_, which allow developers to manage the execution of tasks within Airflow.
+* :doc:`Plugins <plugins>`_, which allow developers to extend internal Airflow capabilities - add new UI
+ pages, custom :doc:`TimeTables <concepts/timetable>`_, :doc:`Extra Links <howto/define_extra_link>`_,
+ :doc:`Listeners <listeners>`_ - all of which are considered public APIs.
+
+Also Airflow has a stable REST API that allows users to interact with Airflow via HTTP requests and a
+CLI that allows users to interact with Airflow via command line commands.
+
+Overall, the public APIs in Apache Airflow are designed to provide developers with a wide
+range of tools and capabilities for interacting with the system and extending its functionality.
+
+What is not part of the Public API of Apache Airflow?
+=====================================================
+
+A public API of Apache Airflow is a set of programming interfaces that are designed to be used
+by developers to access certain features and functionality of the system. As such, not everything in
+Apache Airflow is considered to be part of the public API.
+
+For example, the internal implementation details of Apache Airflow, such as the specific algorithms
+and data structures used to manage DAGs and tasks, are not considered to be part of the public API.
+These implementation details are not intended to be used by external developers, a
+nd are subject to change without notice.
+
+Additionally, certain features and functionality of Apache Airflow may not be exposed through the public API,
+either because they are not considered to be stable or because they are not intended for external use.
+In these cases, developers may not be able to access these features through the public API,
+and should instead use other available methods for interacting with the system.
+
+Similarly, :doc:`Database structure <database-erd-ref>`_ is considered to be an internal implementation
+detail of Apache Airflow and you should not assume the structure is going to be maintained in
+backwards-compatible way.

This is done by me.
