My plugin does not need an API key. It uses an iframe to show Google Maps. That is why my plugin does not support as many advanced features but it is much easier for many people to use.
Hmm. The Google Maps Embed API Developer Guide says
To use the Maps Embed API, you must include a free API key when making a request to the API.
That sounds like even a simple iframe embed needs to include an API key (attached to billing). Are you sure this plugin doesn’t need an API key?
I am not using the Maps Embed API. This plugin works like the share button on Google Maps. When you click that button it give the code for an iFrame. My plugin works the same way. No API key is required.
