# What can you do with Casafari data? Use cases for agents, investors, developers and AI agents

> **Casafari is the AI agent-native real estate data intelligence platform.** The most complete property index in Europe: a deduplicated, cleaned property graph of residential and commercial property, for sale and for rent, in 16 countries. Every property is one record with its full price and market history. [How the property graph is built](/docs/property-graph).

Casafari is the AI agent-native real estate data intelligence platform. Its data is a deduplicated, cleaned property graph: one record per property, with every price and status change dated, across 16 markets. The same data is served to AI assistants over the Casafari MCP server (https://mcp.casafari.com/, 22 data tools in 3 products plus `list_servers`) and to applications over the REST API at https://api.casafari.com (39 operations). This hub groups the outcomes people come for: price a home or a plot, understand an area, catch leads the moment the graph changes, screen investments, build property data into a product, and find agencies and agents to partner with in Germany. Each page states exactly which tools or REST operations to call, in order, and which access each step needs; all of them are available to Casafari clients with their Casafari account. Every page is also Markdown: append `.md` or send `Accept: text/markdown`.

## Value and compare

Price a home, a plot or a commercial unit from comparable properties, past sales and rentals and official registry records, and turn the result into a client-ready report.

- [How do I value a property with comparables?](/docs/use-cases/value-a-property-with-comparables): A defensible asking price, backed by comparables and registry records, wins mandates and shortens time on market.
- [How much rent can I ask for this property?](/docs/use-cases/estimate-rental-price): Setting rent from real rental comparables fills units faster without leaving money on the table.
- [How do I value a property in Spain from its cadastral reference?](/docs/use-cases/valuation-by-cadastral-reference-spain): Valuing straight from the cadastral reference removes address errors and speeds up appraisal workflows in Spain.
- [How do I find comparables for a shop, office, warehouse or plot?](/docs/use-cases/value-commercial-property-or-plot): Commercial and land deals are priced on thin evidence; comparables from one deduplicated graph give a number you can defend.
- [How do I turn comparables into a client-ready CMA report?](/docs/use-cases/cma-report-for-clients): A polished, data-backed CMA is the document that converts a valuation visit into a signed mandate.

## Understand an area

Area Insights: prices, supply and activity over time, distributions by price, bedrooms and time on market, heatmaps by district and automated market reports.

- [How have asking prices per m² moved in an area over time?](/docs/use-cases/price-per-sqm-trend-in-an-area): Knowing the direction and speed of prices in an area turns a gut feeling into advice a client or a committee will act on.
- [Which districts of a city are the most expensive, the busiest or growing fastest?](/docs/use-cases/compare-neighbourhoods-heatmap): Seeing a whole city district by district in one call shows where demand, supply and price pressure actually sit.
- [Is it a buyer's or a seller's market in this area?](/docs/use-cases/supply-and-demand-in-an-area): Reading supply against absorption tells you when to list, when to buy and how hard to negotiate.
- [How long will a property take to sell or rent in this area?](/docs/use-cases/how-long-to-sell-time-on-market): Pricing into the band that sells fastest is the difference between a quick sale and months of price cuts.
- [What does a 2-bedroom apartment cost in this area, and how are prices spread?](/docs/use-cases/price-by-bedrooms-and-price-bands): Knowing the going price for each bedroom count and where supply clusters lets you position a property, or plan a development, against real stock.
- [How do I build a monthly local market report with Casafari data?](/docs/use-cases/local-market-report): A regular, data-backed market report positions an agency as the local authority and keeps it in front of future sellers.
- [How do I analyse a zip code or postcode area with Casafari?](/docs/use-cases/analyse-a-postcode-area): Agents and investors think in postcodes; working on the exact boundary keeps analysis and leads inside the territory that matters.

## Find leads

New Market Leads: alert feeds that follow the property graph for private sellers, price cuts, new properties, reservations and sales, delivered to a webhook or read on demand.

- [How do I find properties newly advertised by private owners?](/docs/use-cases/private-seller-leads): Owners selling alone are the agents' best mandate prospects, and being first to call them is what wins.
- [How do I find properties with price reductions, especially repeated cuts?](/docs/use-cases/price-cut-leads-motivated-sellers): Repeated price cuts are the clearest public signal of a seller ready to deal, for a buyer or for an agent offering a fresh strategy.
- [How do I get real-time property alerts for my filters delivered to a webhook?](/docs/use-cases/new-property-alerts-to-webhook): Hearing about a change in the market minutes after it happens, in your own system, is the whole edge in lead generation.
- [How do I track what competing agencies are selling, reserving and removing in my area?](/docs/use-cases/monitor-competitor-agencies): Knowing who holds the stock, and who just lost or won a mandate, tells you where to compete and whom to recruit.
- [How do I find bank-owned and auction properties in an area?](/docs/use-cases/bank-owned-and-auction-properties): Bank and auction stock is where discounts live, and the first investor to see it sets the terms.

## Screen investments

Find properties priced below the area, estimate gross rental yield and spot motivated sellers by combining Property Sourcing, Area Insights and comparables.

- [How do I find properties priced below the area's market value?](/docs/use-cases/find-underpriced-properties): Buying below a data-backed market value is the only return you lock in on day one.
- [What gross rental yield can I expect in this area, and which properties beat it?](/docs/use-cases/rental-yield-by-area): Yield is the number every buy-to-let decision hangs on, and computing it from one deduplicated graph avoids double-counted supply.

## Property data in your product

Property Sourcing over REST: search the graph, fetch one property with its history, resolve a portal or agency ad id to its property, and share selections.

- [How do I look up one property and see every price and status change?](/docs/use-cases/property-price-and-status-history): A property's full price and status history is the negotiation leverage and the due-diligence record no single portal can give.
- [How do I resolve a portal or agency ad id to the property it belongs to?](/docs/use-cases/match-advertisements-to-one-property): Counting one property once removes duplicated supply from your product, your statistics and your users' inboxes.
- [How do I build property search into my application with the Casafari REST API?](/docs/use-cases/property-search-api-for-your-app): Building on a deduplicated graph with full history gives your users a cleaner search than any single source could.

## Agency partnerships in Germany

AgentGraph AI: screen agencies and agents against partner profiles, map territories, benchmark areas and watch the agencies that matter.

- [Which agencies in a German city are worth partnering with?](/docs/use-cases/find-partner-agencies-germany): Partnering with the right agencies at the right moment, growing independents or franchise offices losing momentum, is how networks expand without guessing.
- [Which individual agents in a German area should I recruit or partner with?](/docs/use-cases/recruit-agents-germany): Recruiting on measured performance and territory signals, not on reputation alone, fills offices with agents who produce.
- [Where should my brokerage open or grow next in Germany?](/docs/use-cases/where-to-open-an-office-germany): Expansion decisions made on measured broker density and demand, district by district, cost far less than offices opened on instinct.
- [How do I get notified when a watched agency or agent changes?](/docs/use-cases/watch-agencies-and-agents-germany): The moment a target agency loses momentum or a star agent moves is the moment to call, and the watchlist is what catches it.

## Property Sourcing

What people build with the Property Sourcing REST API. [All Property Sourcing use cases](/docs/property-sourcing/use-cases).

- [Deduplicated buyer shortlist from a plain-language brief](/docs/property-sourcing/use-cases/deduplicated-buyer-shortlist-from-a-brief): Turn a client's brief into one deduplicated property record per home with Casafari's describe search, matched tags and price per sqm.
- [Price-per-sqm value screen across European markets](/docs/property-sourcing/use-cases/price-per-sqm-value-screen-across-markets): Use one Casafari search body per country, sorted by price per sqm, then read energy rating, condition and price history before bidding.

- [New-supply digest for a farm area](/docs/property-sourcing/use-cases/new-supply-digest-for-a-farm-area): Poll Casafari daily with sort=newest for your farm area, diff first_seen and property ids, and send a deduplicated digest of new homes.
- [Grounded property tool for an AI assistant](/docs/property-sourcing/use-cases/grounded-property-tool-for-an-ai-assistant): Expose Casafari's describe search, property read and resolve as tools; the agent learns them from /openapi.json and /llms.txt and handles 402 and 429.
- [Short-let investor filter with rental licence](/docs/property-sourcing/use-cases/short-let-investor-filter): Combine Casafari's features and exclude_features filters with price-per-sqm sorting to find homes with a rental licence, terrace and parking.
