Redfin Open Houses

GET https://scrappa.co/api/redfin/open-houses
Get API key Open Playground

List homes for sale that have an upcoming open house. Every row includes the open house start, end and label (for example "OPEN SUN, 1PM TO 3PM") next to the usual listing fields. Redfin cannot filter open houses itself, so Scrappa checks the 350 top-ranked listings of the region and returns only the rows with an open house, sorted by start time. The response states how many listings were checked, how many open houses were found and whether another page exists.

Cost: 1 credit per successful request. Failed requests are not charged.
