Update AssetPair.php
asset2 is not necceccary for the api request. And its even possible to send more than two assets to the api.
Could you please get links to API where I can read about this case. And also it will be awesome to cover changes with unit tests.
The Api Documentation is: https://docs.kraken.com/rest/#operation/getTradableAssetPairs Ye, its not obvious that this endpoint is possible with one or more than two AssetPairs. But just check: https://api.kraken.com/0/public/AssetPairs?pair=ETHXBT%2CBTCUSD%2CXLMUSD%2CDOTUSDT That are four AssetPairs. Or: https://api.kraken.com/0/public/AssetPairs?pair=ETHXBT Thats just one AssetPair.
Thanks, despite the long delay)
