# Comparables with Transactions REST API

> **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).

Everything Comparables returns, plus registered closing prices: Spain's notary deals, Italy's registered sales from Agenzia delle Entrate and Poland's RCN official register (`transactional_data`), France's DVF public register (`dvf_results`). The same input as Comparables.

1 operation on the platform's REST API, base `https://platform.casafari.com/v1/comparables-transactions`, with a platform API key from [the console](https://platform.casafari.com/console) ([platform API keys](/docs/rest#platform-api-keys)), billed in tokens (1 token = EUR 0.04).

Over MCP, Comparables with Transactions has 1 tool: see [Comparables with Transactions](/docs/comparables-with-transactions) and [MCP and REST compared](/docs/parity#comparables-with-transactions).
