Need Help to Create Loan App

As We know that there are so many LOAN apps available on PlayStore which gives you small amount of loan for a week or twice. In that app, User entered his details and company automatically get his CIBIL score and provide him loan according to his CIBIL score. Is anyone tell me that how we check CIBIL of User who register??? I Mean is there any Exention or any other way to do it?

CIBIL is way to know about user’s financial repayment regularitiy which measure using Score From 300 to 900.
