Get data from Rest Api

The project is as follows.

There is a public api with the methods:

/zipcodes/{zipcode}
/zipcodes/{zipcode} /payments_cube get
/zipcodes/{zipcode} /consumption_pattern get
/zipcodes/{zipcode} /payment_distribution get
/zipcodes/{zipcode} /basic_stats get
/zipcodes/{zipcode} /gender_distribution get
/zipcodes/{zipcode} /cards_cube get
/zipcodes/{zipcode} /category_distribution get
/zipcodes/{zipcode} /age_distribution get
/zipcodes/{zipcode} /customer_zipcodes

the developer will receive access to this api and a list of a few thousand zipcodes.

The project consists of:

_Calling the methods for each zipcode.
_receiving the response in either in json or xml format.
_And creating a XLS for the united data.

For example:

1) Call method BASICSTATS for zip codes [00000 to 10000]
2) Received responses [00000.xml to 10000.xml]
3) Unite re responses for zip codes [00000 to 10000] in one tabular format: csv, xls, etc.

The project deliverables are:
_ Responses received (Xml files).
_ xls files with compiled data (one per api method).

Notes:
_ The API has a web Console for testing.
_ The API closes its service on 2014-dic-01 so the calls must be made before that date.
