# What are tokens on the Casafari platform?

> **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 token is how the Casafari platform counts usage: every call costs a set number of tokens, and some calls cost less in an AI assistant, over MCP, than over the API.

- Place lookups ([Location Lookup](https://developers.casafari.com/docs/references)) and the account status check are free.
- What a REST operation costs is on its page in the [REST reference](https://developers.casafari.com/docs/rest), and the response headers `Casafari-Units-Charged` and `Casafari-Units-Remaining` say what a call cost and what is left.
- What the common calls cost over the API and in AI assistants, side by side, what the plans include and what a token costs are on [Pricing](https://developers.casafari.com/pricing).
- How many tokens a plan lets you use in any 3 hours or 7 days, and what happens when they run out, are on [Limits and usage windows](https://developers.casafari.com/docs/limits).

To see where you stand, ask the assistant to call `account_status`, or call `GET /v1/account`.
