# Information Retrieval (GET)

#### The QR MIA API provides multiple GET methods that allow retrieving information about the generated QR codes.

These methods are useful for merchants and integrators who want to:

* check the current status of a QR code at any time (e.g., active, paid, expired, etc.),
* filter or sort existing QR codes based on various criteria (amounts, dates, types, statuses, etc.),
* access complete details about a specific QR code or a set of QR codes within a time range.

All this information is also automatically delivered via the callback mechanism.
