# AVM API

Query the AVM API for a Dutch home, by zip code and house number, to get the market value on the valuation date from more than 150 real-time variables.

## Introduction

With the AVM, Altum AI creates unique insights into property values ​​for homes in the Netherlands. The source for calculating the market value of a house is the so-called Automated Valuation Model (AVM) of Altum AI. This model works with more than 150 variables per home that update in real-time. Consider known variables such as living area, content, and plot area.&#x20;

## How to use

To be able to deliver the AVM market value and object details, we need to identify the object based on the zip code and house number details. &#x20;

Depending on the object, house-type, and input, we generate a response. This response covers the details about the home, such as the address, building type, building year, inner surface area, and if available current energy label.&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.altum.ai/english/property-valuation-and-market/avm-api.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
