Pulls genuine, currently-active for-sale listings for a US city/state from the RentCast API and publishes them free.
Data only — no photos (RentCast doesn't provide them). Requires RENTCAST_API_KEY to be set as a site env var.
Bulk sync major markets
Runs the sync above once per market, one at a time. Each market = 1 RentCast API call —
the free tier is 50 calls/month, so the default list below (25 markets) leaves headroom. Edit the list freely.
