# Authentication

The only step required to authenticate your requests is to include an API key in the header of your requests.
Please contact us in the chat or at [support@hellodata.ai](mailto:support@hellodata.ai) so that we can generate a key for your account.

Once generated, you'll be able to find your API key in the API section of the platform, and authenticate your requests by including it in a `x-api-key` header for each request.

```bash
curl --location 'https://api.hellodata.ai/property/search?q=111%20w%20wacker' \
--header 'x-api-key: <your-api-key>'
```
