The brothers open an API, or application programming interface, for their index so that developers can build applications using it. Cameron:
We’ve spent a lot of time trying to build a really cool tool. 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…It’ll be really interesting to see what people do. And even though ostensibly an API of a pricing product is not super sexy, this matters to the Bitcoin community.
