Verizon Wireless will soon publish an API that allows users to temporarily “turbocharge” their data speeds for a fee. The new API must be implemented into mobile apps by their developers, and it will offer users a “turbo button” that gives individual apps a speed boost. PCMag reports that the service will be tied to an on-device payment system, and subscribers will have to pay each time they want to temporarily increase their data speeds. These pay-per-use speed boosts will also be given priority when Verizon’s network is congested. In order to work, the turbocharge feature requires that an app utilize a “network optimization API” that Verizon doesn’t expect to publish until the third quarter next year.
