TrialPay

TrialPay was an alternative-payments and offer-based advertising company founded in 2006 and based in Mountain View, California, backed by Battery Ventures among others. Its platform let merchants and game developers offer users a product for "free" in exchange for completing an advertiser-sponsored action (a purchase, trial, or signup), with the advertiser paying the merchant — monetizing users who would not otherwise pay. TrialPay shipped web, Android, and iOS SDKs plus offer-wall and monetization APIs (e.g. GetBuyCoinsInfo / GetBuyDirectInfo) widely used in social and mobile games. Visa acquired TrialPay in April 2015 and folded the technology into the Visa Commerce Network; TrialPay no longer operates as a standalone company and its public developer surface (help.trialpay.com, trialpay.com) is offline.

TrialPay is profiled on the APIs.io network. Tagged areas include Company, Payments, Advertising, Monetization, and Offer Wall.
