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 Offerwall.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
