Is it possible to make a call to an Azure API Rest url without a subscription key?

I just want to be able to do a rest call using Azure Web Api Management without needing to pass the subscription-key in the url. Is that possible?

How do I connect to Azure API?

Select Azure Active Directory > App registrations, and then select your client application (not your web API). Select API permissions > Add a permission > My APIs.

What is subscription key in API?

What are subscriptions? By publishing APIs through API Management, you can easily secure API access using subscription keys. Developers who need to consume the published APIs must include a valid subscription key in HTTP requests when calling those APIs.

Azure API management allows for anonymous subscriptions.

Create a Product without requiring a subscription (Product -> Settings -> Require Subscription) Add your API to this product.
