The basic subscription button profile IDs are not support by the GetRecurringPaymentsProfileDetails API. This API would only work for subscriptions or recurring payment profiles created via the CreateRecurringPaymentsProfile API through Express Checkout which is our API based checkout solution. Website Payments Pro is not required to use Express Checkout. I know this can be frustrating and we recommend that merchants collect basic subscription information via IPN to store in their own database or view the information on their PayPal account. This has also been submitted as a feature request by our Merchant Technical Services team.

You only can check the Status of such an Agreement when you use a url like:

$url = 'https://api.paypal.com/v1/payments/billing-agreements/'.$z_res[0]['id_agreement']."/transactions?start_date=".substr($logdbarray['Deal_Start'],0,10)."&end_date=".substr($now,0,10);

Here you will get a list of trsansactions. When the last transaction in not status:canceled then the agreement still runs. You will get dates of transactions as well so you can define if you agree to use your paid service or not.
