# What does Comparables & Valuation do?

> **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).

Comparables & Valuation returns comparable properties and estimated prices for a home, matched around a point, an address or a cadastral reference.

It draws on properties on the market, past sales and rentals, and official registry records.

Over MCP, it has 1 tool, [`comps_get-comparables`](https://platform.casafari.com/docs/comparables-valuation/get-comparables). The tool takes a circle (target point and radius in kilometres) or a closed polygon, an operation (sale or rent), property types and optional filters. It returns:

- Ranked comparables with a similarity score
- Aggregated statistics (average price, price per m², time on the market)
- Estimated prices: fast-sell, fair-market and out-of-market

The cadastral-reference input is for Spain only.

Over REST, it has 4 operations: [`POST /api/v1/comparables/search`](https://platform.casafari.com/docs/rest/comparables-valuation/search-comparables-v1), [`POST /api/v2/comparables/search`](https://platform.casafari.com/docs/rest/comparables-valuation/search-comparables-v2), [`POST /api/v1/valuation/comparables-prices`](https://platform.casafari.com/docs/rest/comparables-valuation/search-estimated-prices-v1) and the REST-only [`POST /api/v2/comparables/ai-builder`](https://platform.casafari.com/docs/rest/comparables-valuation/initialize-an-ai-builder-session-v2).
