❓ FAQ

Which collector-car auctions are supported?

The first release supports public Bring a Trailer and Hagerty Marketplace outcome pages. Other marketplaces are excluded until their access and usage conditions are suitable.

Does it get blocked?

The supported pages were selected because their public auction content is available without a login. Optional network routing can help with ordinary regional connection issues.

How fresh are the auction results?

Each run reads the public page at run time. Schedule repeat runs when you need a regular sold-comp or outcome-change feed.

How does change detection work?

The Actor stores each listing's last observed status and price. Later runs mark new records and genuine changes without inventing missing history.
