I’d like to introduce you to my weekend project, bitcoinprices.js.
The project was born out from the frustration, because many small Bitcoin eCommerce sites have prices only in raw BTC. This makes it very hard for an average eCommerce site user to value the sold items.
The exchange rates data is sourced from bitcoinaverage.com, but this can be easily changed.
Kudos for bitcoinaverage.com guys for the great service.
