# Example Call

Here is an example of a `curl` command for uploading device ownership data. In your API requests, the `publisher` and `owner` fields are required. 

{% hint style="warning" %}
If these fields are incorrect or missing, you will receive a 400 error.
{% endhint %}

* `publisher`: This should match the device used in the `/upload-device-metrics` API.
* `owner`: This should be the wallet address of the device owner where they receive rewards.

#### Example request:

```bash
curl -X POST 'https://api.depinscan.io/api/project/78a4c60c-**/ownership' \
-H 'Content-Type: application/json' \
-H 'Authorization: mc.' \
-d '{
"publisher": "device_1",
"owner": "0x1234567890abcdef1234567890abcdef12345678"
}'
```
