New-supply digest for a farm area
For Agents prospecting for sale mandates. Poll Casafari daily with sort=newest for your farm area, diff first_seen and property ids, and send a deduplicated digest of new homes.
Why is fresh supply hard to see?
A new property appears on several portals and agency websites at different moments, so a street-by-street check shows the same home repeatedly and can miss one advertised only on an agency's own website. Speed matters: in Portugal the average time a sale advert stayed active fell from 161 days in 2024 to 110 days in 2025, according to Construir.
How does it work step by step?
- Find the area once.
GET /v1/locations/searchfor the neighbourhoods you farm; keep thelocation_ids. - Poll. Each morning,
POST /v1/property-sourcing/searcheswith those ids,operation: "sale",sort: "newest"andpage_size: 100. - Stop early. Read results until
first_seenis older than your last run; follow the cursor only if the whole page is new. - Diff. Compare
prop_…ids with those already seen and keep the new ones. - Enrich.
GET /v1/property-sourcing/properties/{property_id}?expand=listingsfor the agency, URL and price of each place a new home is advertised, then send the digest.
curl -X POST https://platform.casafari.com/v1/property-sourcing/searches \

-H "Content-Type: application/json" \
-d '{"location_ids": [12345], "operation": "sale", "sort": "newest", "page_size": 100}'What do you get?
A deduplicated list of properties newly on the market in your area with price, price per sqm, bedrooms, living area, coordinates, first_seen and listings_count, ready for a morning email or a CRM import. For homes already on the market that keep cutting price, pair the digest with High Potential Seller Leads.
What are the limits?
This gives the earliest visibility of advertised supply, not off-market or pre-market property: a home enters the graph when it is advertised on a portal or agency website. A one-page daily run costs 100 units a day, about 3,000 units a month, more than the 1,000 units Free includes for 30 days; Free also allows 10 distinct places a day.
