Property data in your product · Use case

How do I look up one property and see every price and status change?

Fetch the property with GET /api/v1/properties/search/{property_id} in Casafari's Property Sourcing REST API. Each record merges every advertisement of one property and carries its full history: every price change, status change, appearance and removal, with dates, in sale_price_history and rent_price_history. First find the id from a portal or agency ad id, or from a reference number.

#Short answer

Casafari collects property advertisements from agency websites and portals in 16 countries. It structures, cleans and deduplicates them, then merges every advertisement of a property into one record. That record carries the property's full history: every price change, status change, appearance and removal, with dates. Prices over time are in sale_price_history and rent_price_history.

You fetch the record over the REST API with GET /api/v1/properties/search/{property_id}, part of Property Sourcing. The property graph explains how the record is built.

#Steps

#Get a token: POST /login

1. Send the account's email and password as JSON to POST https://api.casafari.com/login. The response holds an access_token and a refresh_token (JWT). Send Authorization: Bearer <access_token> on every call. Renew the token with GET /refresh-token when it expires.

#Find the property id: from a portal or agency ad id with POST /api/v1/properties/match-by-listings, or by ref_numbers with POST /api/v2/properties/search

2. If you hold a portal or agency ad id, send it in listing_ids to POST /api/v1/properties/match-by-listings. The operation resolves the ad to the property it belongs to.
3. If you only hold the agency's own reference number, send it in ref_numbers to POST /api/v2/properties/search. Add location_ids to narrow the search.

#Fetch: GET /api/v1/properties/search/{property_id}

4. Call the operation with the property id from step 2 or 3. It returns the property and its history.

#Read sale_price_history, rent_price_history and the status fields

5. Read sale_price_history for asking prices on the sales market and rent_price_history for the rental market. Each change carries its date.
6. Read the status fields for the property's current state on each market. In Casafari property records these are sale_status and rent_status. The operation's reference page has the full response schema.

#Example

A buyer's agent in Lisbon has the id of a portal ad for a flat. They want to know how long it has been offered and at what prices.

POST https://api.casafari.com/login
Content-Type: application/json

{ "email": "agent@example.com", "password": "<password>" }

POST https://api.casafari.com/api/v1/properties/match-by-listings
Authorization: Bearer <access_token>
Content-Type: application/json

{ "listing_ids": ["<portal ad id>"] }

GET https://api.casafari.com/api/v1/properties/search/<property_id>
Authorization: Bearer <access_token>

The condensed record below shows field names only. Values are elided. The exact shape of each history entry is on the reference page and in the public OpenAPI description at https://docs.api.casafari.com/openapi.json.

{
  "property_id": "<property_id>",
  "sale_status": "...",
  "rent_status": "...",
  "sale_price_history": ["..."],
  "rent_price_history": ["..."]
}

#How to read the result

Read the history in date order.

• First appearance: tells you how long the property has been offered.
• Each price change: shows the direction and size of the move.
• Removals followed by reappearances: show whether the property was withdrawn and offered again. This answers the question "was this home on the market before?"

A long history with several cuts is negotiation leverage for a buyer. For a valuer, lender or due-diligence team, the same history is a dated record of how the market has treated the property.

#Statuses: active, reserved, hold, sold, rented

The graph records each status change with its date:

• On the sales market a property can be active, reserved, on hold or sold.
• On the rental market it can be active, reserved, on hold or rented.

Read a status as the property's state on the market as the graph observed it from the advertisements.

#Several agencies, one record: the agencies linked to the property

When several agencies and portals advertise the same property, Casafari recognises them as one property. It keeps one record that links the advertisements, agencies, agents, location and history. You therefore read one history, not one per advertisement. Agency names match the values from GET /api/v1/references/agencies.

#Limits

Property Sourcing is REST only and not offered over MCP. Its steps on this page, resolving an ad id or a reference number to the property and fetching the property with its history, are self-serve on the Casafari API and MCP Platform and stay available to Casafari clients with their Casafari account.

The sources give no figures for pricing, quotas, rate limits, refresh frequency or SLAs. Ask Casafari at https://www.casafari.com/.

#Self-serve over REST; MCP does not search or fetch properties

None of Casafari's MCP servers has a tool that searches or fetches properties. A request such as "show me the price history of property 123456" made to an assistant connected over MCP cannot be answered from Property Sourcing. Your own code, or an agent with a REST token, calls the operations above. See Can I search properties over Casafari MCP?.

#History covers what the graph observed since the property first appeared

The history starts when the property first appeared in the sources Casafari collects. A property never advertised in those sources has no history in the graph. Changes made before its first appearance are not recorded. The history shows asking prices and statuses on the market; it does not tell you the price a buyer finally paid.

#Ask in Claude or ChatGPT

Property Sourcing has an MCP server, https://platform.casafari.com/mcp/property-sourcing, so an assistant can run this from a chat. In Claude or ChatGPT, add a custom connector with that URL; in Claude Code: claude mcp add --transport http casafari-property-sourcing https://platform.casafari.com/mcp/property-sourcing. Sign in with your Casafari Platform account in the browser (a new account starts on the Free plan). Then ask, for example:

Flats in Madrid under €650K, 2+ bedrooms: show each with every agency advertising it and its price history.

The assistant finds the place with locations_search (free), searches with property-sourcing_search (50 tokens a page, property-sourcing_next_page for more), reads each home with property-sourcing_get_property (10 tokens: every agency and portal advertising it and its asking price history) and turns a pasted portal or agency link into its home with property-sourcing_resolve_listing (25 tokens). Prices are asking prices. See Property Sourcing.
