Hocam doviz.com ile bir çekiyorsun iki çekiyorsun en nihayetinde engelliyor. Sağlam bir proxy ile yapabilirsin ancak. Muhtemelen null dönmesinin sebebide bu. Garanti bankasınında öyle olduğunu düşünüyorum. Daha önce bununla çok uğraştım. En sonunda foreks.com şirketinden servis olarak alabiliriz durumu oldu. Maliyeti aylık 150 dolardı. Firma kabul etmedi. Projede rafa kalktı böylece.

Hocam çekememen normal zira döviz kurları sayfa yüklendikten sonra XHR ile ikinci bir istek ile gerçekleşiyor; aşağıdaki arkadaşı deneyebilirsin, göndermen gereken zaruri header bilgilerini de içeriyor ve cevap olarak json dönüyor; guid ve x-client-trace-id "-" karakterleri olamdan standart GUID, random oluşturup da gönderebilirsin sanırım. credentials omit ile de çalıştığına göre sanırım zaruri headerleri karşılasan yetecek, session bazlı bir geçici bir kontrol var gibi hissettirmedi.
