Coinabul is the first service that allows users to purchase gold using bitcoins. Gold and bitcoin prices are updated every minute, ensuring that the prices buyers see on the website are the prices they'll be paying. Coinabul uses special shipping infrastructure that includes insured shipping and nondescript packaging to ensure that orders arrive safely. The Coinabul API allows users to retrieve a data feed of bitcoin and gold prices, both in terms of each other and in U.S. dollars. Users can also place orders via API.
