Small PHP Wordpress API Implementation

Job ID: 31903633

Budget: $10 – $30 USD

I need someone to code me a simple PHP Wordpress addition that has the following functionality:

Must be able to process a web request like http://www.url.com/verify?key=74CA65F8-8F43-4DE1-9842-82139086DFA8

Then check then this key against the local websites database if it exists there and return a simple boolean true/false to the client.

In Wordpress admin area there needs to be a new tab where these keys are listed with the option to "Add a Key" and "Delete a Key". The display of each key needs to be together with an “Activation Counter”. Every time a request for a key is successful this counter needs to decrement by one. If the count reaches zero the reply for the request needs to be false. The Activation counter value needs also to be editable.

Needs to be very robust e.g. no injection attacks possible and absolutely reliable/bug free.
Credentials to a blank wordpress install will be provided.
