The people API has two settings.

http://worldofspectrum.org/infoseek/api/people?X-API-KEY=test

This produces a list of people.

The results returned are:-

ID - The unique infoseek ID for the person
Person - The name of the person
Slug - The URL slug of the person
Pictures - A list of images used for the person

The people list can accept several optional parameters.
limit - Set the number of records to retrieve. The test API has a maximum of 10
offset - Offset the search results
person - you can search for specific people. You can use wildcards here. For a specific match use  '_hewson'. Starts with - 'hewson%', or ends with: '%hewson'. By default the search is both start with and ends with.
random - This returns a random list based on the search criteria
 

The other search is for an individual publisher. This requires one of two parameters:

http://worldofspectrum.org/infoseek/api/person?X-API-KEY=test&id=9730

id - the infoseek ID of the person
slug - the slug of the person.

Data returned is the same as the publishers list above, however there are also a series of optional parameters to return further results:
Books - A list of books related to this person.

NOTE - MORE OPTIONS WILL BE ADDED AS MORE DATA IS LOADED INTO THE NEW SYSTEM
