Is there any paid blossom server that charges based on usage with a proper nostr login web interface to manage and see all the media and how much each is costing you, with DM alerts when usage spikes or balance running low? Because this is what we need right now. No one wants to start paying a fixed monthly fee before they have any media to pay to host. Even if it is more expensive with high usage, the pay as you go approach will charge those higher amounts only after the user has a ton of data they are paying to host.
