Based on a list of phone numbers, get information from Truecaller

I have an excel with list of 15000 names and phone numbers. I need all information what all true caller give . I have truecaller installed on my phone and when I enter the phone number, I understand truecaller has sdk/api through which this process can be automated. Please let me know the charges for giving me a automated software and also confirm me what will be the charges if true caller changes something and it stop working to repair it so I can give you one time app making charge and And when it stops I can make tell you and you can make it work again
