# What are units on the Casafari platform, and how many does each request cost?

> **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).

A unit is the self-serve platform's billing atom: every operation costs a fixed whole number of units, the same over MCP and REST, from 0 to 2,500.

- **Location Lookup** (place lookups) and account calls: 0 units ([location lookups](https://developers.casafari.com/docs/faq/location-lookup-free)).
- **Area Insights**: 5 or 10 units per operation (0 for the current date).
- **Comparables & Valuation**: 20 units per operation.
- **[AgentGraph AI](https://developers.casafari.com/docs/faq/what-is-agentgraph)**: 10 to 20 units for profiles, maps and benchmarks, 250 to screen agencies or agents, 2,500 for a partner brief.
- **Alerts**: 20 units to create a feed, 5 to update one, 1 per delivery, otherwise 0.

The Free trial has 1,000 units: a partner brief costs more than that. More units are [credits](https://developers.casafari.com/docs/faq/what-are-credits) at €0.04 a unit, excluding VAT. Agent plan usage is also metered in [usage windows](https://developers.casafari.com/docs/faq/usage-windows); follow yours in [usage and balance](https://developers.casafari.com/docs/faq/check-usage-and-balance).
