This tag is for questions about the use of, or documentation of, the **Stack Exchange** Application Programming Interface (API).

The Stack Exchange API provides easy programmatic read/write access to the more common functions of the Q&A sites in the Stack Exchange network.  
For example, it allows programs to read and write: questions, answers, and comments.
