# Woningwaarde API

Bent u geïnteresseerd in de exacte, actuele waarde van een woning op dit moment zonder verdere poespas? Dan is dit de oplossing die u zoekt. Dit endpoint geeft de waarde terug van elk (woon)object in Nederland zoals bepaald door ons AVM model. Dit Machine Learning model bepaalt aan de hand van tientallen pand- en omgevingseigenschappen zeer nauwkeurig de marktwaarde van de woning

### Voor wie is het?

* U bent op zoek naar een accurate woningwaarde maar hebt geen interesse in verdere metadata
* Ideaal voor bijvoorbeeld lead generation op uw website vanwege de lage kosten en beperkte benodigde bandbreedte.

### Wat moet ik weten?

* Het Matrixian AVM is gerenommeerd en wordt gebruikt door verschillende brancheorganisaties in de taxatie- en makelaarswereld
* Het model wordt continu beoordeeld en verbeterd zodat we nooit achterlopen op de markt en u zeker bent van betrouwbare informatie
* Locatie, locatie, locatie! Prijstrends, referentieverkopen en gebiedskenmerken worden allemaal meegenomen in het model

## GET /homevalue/value

> Returns the market value prediction.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.matrixian.com/waarderen-en-taxeren/woningwaarde-api.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
