Is it possible to implement One-Click Purchase using Paypal API? or Paypal Adaptive API? Instead of asking the user to login each and every time.
Thanks in advance.

To have a "one click checkout" experience with Paypal, solution is the "Preapproved Payments Flow" from the Adaptive payment.
The following diagram shows the basic flow of control during a preapproval operation.
After the sender sets up the approval, you can make payments on the sender’s behalf directly. The sender is no longer required to log in to PayPal to complete the payment.

I don't think that is the way you are looking to do it but it's the only way PayPal's API will allow it.

that's correct Adaptive Payments Preapproval API is the best way to do this: https://www.x.com/developers/paypal/how-to-guides/how-set-payment-preapproval-using-adaptive-payments
You could also use the Reference Transaction APIs too - you can find the how-tos for those here:
- Cards
- PayPal Accounts
