Price Suggestions
ProtonAuctions is in public beta. See Beta Phase for what is stable and what is still maturing.
The engine works out what items are worth on your server, and players meet that pricing where they are already looking: on the listings themselves. Browsing shows a market-value hint and a Great Deal or Overpriced badge on each listing, and pricing something far above its worth with /ah sell triggers a friendly warning first.
There is also an optional /ah suggest command for players who want to check a price on demand. It is on by default, but it is the extra, not the main event.
Wherever a price appears, it comes from the same learned model, and the engine stays silent when it is not confident enough.
