The API is fairly standard, allowing developers to access most of the functionality of the WinkDex itself. This will prove useful for developers building bitcoin apps, although there are many other sources for such data.
Speaking with Fortune, Cameron Winklevoss said that while the main function of the WinkDex was for use in his company’s EFT, he hopes to see the index gain a following. “We’ve spent a lot of time trying to build a really cool tool,” Cameron Winklevoss said. “Obviously the index will be big for us because it will be used to price any future ETF. But we also wanted to build on this for the betterment of the Bitcoin community.”
Although the WinkDex pricing formula isn’t inherently more accurate than any other index, being simply an adjusted average price from the three major exchanges, as the official price index of the WBT it would become an increasingly important source for the “true” price of bitcoin should the ETF actually launch.
