AwardWallet was established in 2004 by Alexi Vereschaga and Todd Mera, two former employees and software engineers from the Aelita Software Corporation. The company began with reward programs by tracking transactions of frequent flyer users and later expanded its services by adding a variety of customer loyalty programs AwardWallet added a companion mobile application for iOS and Android devices circa 2010/2011. As of 2021, AwardWallet had over 700,000 members. AwardWallet software has been discussed and cited in travel and technology sections of the media outlets such as The New York Times, BBC, CNN, Bloomberg, Forbes, Entrepreneur, Vox Los Angeles Times CNBC and The Wall Street Journal, among others. Technology
AwardWallet's software is equipped with several APIs related to the travel space including an AwardWallet Email Parsing API, AwardWallet Web Parsing API, and AwardWallet Account Access API. For example, Email Parsing API retrieves travel reservations from confirmation emails. Travel reservations are then parsed by the API to return the reservation data in a structured JSON format The AwardWallet Account Access API operates via OAuth protocol. The AwardWallet Web Parsing API retrieves account balance, membership tier, expiration date and more from online accounts. It also provides access to travel itineraries and historical account activity. A number of sources indicate that the AwardWallet software is a part of an emerging API economy. Airline companies tracking controversy 
AwardWallet was a part of controversy related to the denial of the airline companies to have tracking software programs in their API systems. In late 2012, AwardWallet (along with TripIt and MileWise) received a number of cease and desist letters from American Airlines, Delta, United Airlines and Southwest Airlines, demanding that AwardWallet discontinue accessing their websites for tracking clients' miles rewards programs. In August 2013, American Airlines resumed its use of the AwardWallet by integrating its software in the company's API. References
