# What is Stream Estate?

> The Stream Estate API is designed to enable builders to easily query, observe, and automate real estate data and insights

The Stream Estate API lets you query, observe, and automate real estate data over
HTTP. Authenticate with the `X-API-KEY` header — here's a working call that returns
houses for sale:

```bash theme={null}
curl -g 'https://api.stream.estate/documents/properties?propertyTypes[]=1&transactionType=0' \
  --header 'X-API-KEY: <your_api_key>'
```
