# What are Casafari credits, and how do I buy more units?

> **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 credits are prepaid units on the self-serve platform at €0.04 a unit, bought as any whole number of euros from €20, with discounts on larger purchases.

- 5% off from €100
- 10% off from €200
- 20% off from €500
- 30% off from €1,000

All amounts exclude VAT. A verified card is needed; in the first 7 days after card verification, a purchase is at most €4,000. Credits cover every self-serve product, priced per operation in [units](https://developers.casafari.com/docs/faq/what-are-units).

Free users may buy credits without subscribing ([trial](https://developers.casafari.com/docs/faq/free-trial)). On the [Agent plan](https://developers.casafari.com/docs/faq/plans), usage beyond the [usage windows](https://developers.casafari.com/docs/faq/usage-windows) is paid from credits only, capped by default at 25,000 units (€1,000) a period. An account on credits with no plan has no windows: it spends only what it bought, at most 25,000 units a day, with the Agent plan's request guards.

When units run out, a person pays through a link ([what to do](https://developers.casafari.com/docs/faq/agent-ran-out-of-units)). Credit expiry, refunds, payment methods and invoices are not published; Casafari can answer ([casafari.com](https://www.casafari.com/)).
