This is out of scope for BTCtoX. I'm not actually getting information about the direct BTC-X exchange rate, but rather going through an intermediary - I'm getting the BTC to USD rate, and then converting USD to all currencies - so I don't have the direct exchange rates.
Could you provide a direct BTC <=> EUR rate instead of going through USD conversion?
I don't understand the relevancy of the URL.
The currently support direct conversion at the UI level ... the displayed rate may differ due to arbitrage.
I have no immediate plans to add a more accurate BTC <=> EUR rate.
