What is the forex markup fee on Indian credit cards?

I travel abroad twice a year. Which Indian credit cards have the lowest foreign currency markup fee for international transactions?

Credit score impact: each hard inquiry (which happens on card application) drops your score by 5-15 points temporarily. Applying for 3 cards in 2 months is fine IF you get all 3 approved. If 2 get rejected, you've taken a hit with nothing to show for it. Apply smart, not fast.
