The method getTradableAssets() does not exist on HanischIt\KrakenApi\Model\ResponseInterface. It seems like you code against a sub-type of HanischIt\KrakenApi\Model\ResponseInterface such as HanischIt\KrakenApi\Call\TradableAssetPairs\TradableAssetPairsResponse.

        echo $assetPair->getAssetPair() . " " . $assetPair->getAltname() . "\n";
