Frequently asked questions
Can I get notified the moment a home's price drops?
Yes. Save the listingId from search, poll this endpoint at a fixed interval and compare the price-event sequence to trigger alerts.
Does it return only price drops?
It returns the listing's price events — reductions and other adjustments — with dates and amounts.
How do I compare cuts against the market average?
Aggregate cut sizes across many listings in the same area to spot market softening ahead of median-price moves.
