Mailgun simple script

I need a light script, compatibles with Mailgun API with 2 main features. The first feature should be able to get all bounces from a domain in mailgun, and store them in a local file. The parameters are API URL (in the code), API key (in the code), DOMAIN (text field) How to do this is here [login to view URL] The second feature should read a local file with emails, and unsubcribe all those emails from a given domain. The parameters are API URL (in the code), API key (in the code), DOMAIN (text fiels), the file where emails are stored. How to do is here [login to view URL] It is best if the file for script 1 can be use by script 2. The script should not use MySQL, only XML or CSV files.
