All requests must use HTTPS. Responses are returned in JSON format.

All requests must include the `X-Api-Key` header:

```bash theme={null}
curl -X GET "https://api.otark.com/v1/assets" \
-H "X-Api-Key: YOUR_API_KEY"
```

API keys can be generated in your [account settings](https://app.otark.com/settings/api-keys). Store your key securely — it grants access to your Otark account.
