# Rental yield screen

> **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).

**Rank areas by gross yield and price momentum.**

You get: Ranked sheet. It uses Area Insights, takes 125 tokens a run (€5.00 at €0.04 a token) and runs monthly. For: Investor or fund.

**Status:** runs today.

## What it does

| # | Step | Product | Tokens |
|---|---|---|---|
| 1 | `POST /v1/area-insights/rental-yield` × 10: ten areas | Area Insights | 100 |
| 2 | `area-insights_get_heatmap` | Area Insights | 25 |

One run: **125 tokens**, €5.00. Each call costs the same over MCP and REST, so the run always costs what the table says. [How many tokens your volume needs](/playbooks), and [plans and credits](/pricing).

## Where it runs

Every country the products it uses cover. The plan names a country that one of them does not.

## Run in Claude

This playbook calls one Casafari MCP server. Add it to Claude, ChatGPT or any MCP client, and sign in the first time you use it (a Free account, no card, is created then; [console](https://platform.casafari.com/console/)).

- Area Insights: `https://platform.casafari.com/mcp/area-insights`

In Claude Code:

```bash
claude mcp add --transport http casafari-area-insights https://platform.casafari.com/mcp/area-insights
```

Then ask:

```text
Run the rental yield screen playbook for Spain every month: call area-insights_get_heatmap, in that order, and tell me what each step cost in tokens.
```

## Get the API calls

The same steps as REST calls, in order. Create a platform API key in the console and export it as `CASAFARI_API_KEY`; each call takes the parameters its operation documents in the [REST reference](/docs/rest).

```bash
# 1. Area Insights (10 times), 10 tokens a call
curl -X POST https://platform.casafari.com/v1/area-insights/rental-yield \
  -H "Authorization: Bearer $CASAFARI_API_KEY"

# 2. Area Insights, 25 tokens a call
curl -X POST https://platform.casafari.com/v1/area-insights/heatmap \
  -H "Authorization: Bearer $CASAFARI_API_KEY"
```
