The service allows researchers to commission surveys which users complete to earn rewards in varying amounts. It emails survey invitations to registered users with links to online questionnaires specified by researchers. Completion rewards may be paid to users by the provider or directly by researchers.
API methods support management of user accounts, with create, update, and delete functions, along with demographic data and other profile information for use in matching users to surveys. Methods also allow listing of available surveys and generation of user emails with questionnaire links. The API also provides for specification and payment of completion rewards.
