I have a Description for the API and want to become a Plugin, what can handle the Requests i need.
It shouldt only display the Records from Api in this Case i need.

Means: The WP Plugin get Datas with geocoded Addresses and show them in Wordpress on
a.) a MAP from Google or others
b.) a List View where i can show all Addresses sorted by user
c.) a Detailview with Map and Gmaps Functions like directions

I need a flexibel Way to edit API request (User must insert a serial to use Api) - Allready in API included - API is finished and works without Problems, Api Descrition is available too.

Shouldt be easy to handle inside the WP Enviroment for no technical Users !
Shouldt be easy to setup for Output, that you can edit the Positions - how to show on what Place, because we use different Templates - so must be easy to edit for the Clients later.
