Every app you use · one catalogue
Pick a route and a country. The page asks that route for its current price and the units left, and prints how long the figure stands. The quote holds that amount in your wallet without spending it. When a number is delivered, the hold settles at the price you read. An expired quote is asked again, so the figure never drifts upward on its own.
Your order page is the only place a delivery appears. A number arrives with its country and the service it was bought for. A code arrives with the minute it stops being useful. A stocked account arrives with the login held on its stock row. Everything stays under your account, and support reads it only through an access link you issue yourself.
Live stock and prices are read from the routes when you ask.
