To utilize Google API within a Blazor WASM PWA without any intermediary steps, you can follow these steps:

1. Create a Google Cloud Platform (GCP) project and enable the Google API you want to use.
2. Generate a Google API key and configure the API restrictions to only allow requests from your PWA domain.
3. In your Blazor WASM PWA project, install the Google APIs client library for JavaScript using a package manager like npm.
4. Add the API key to your PWA's index.html file using the meta tag provided by Google.
5. Use the client library to make API calls from within your Blazor components.

Here's a sample code to load the Google Maps API from within a Blazor component:

@page "/googlemaps"
@inject IJSRuntime jsRuntime

<div id="map"></div>

@code {
    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            await jsRuntime.InvokeVoidAsync("loadGoogleMapsApi", apiKey: "YOUR_API_KEY");
        }
    }
}

And here's some JavaScript code to load the Google Maps API asynchronously:

window.loadGoogleMapsApi = async function(apiKey) {
  const scriptElement = document.createElement("script");
  scriptElement.src = `https://maps.googleapis.com/maps/api/js?key=${apiKey}`;
  scriptElement.type = "text/javascript";
  scriptElement.async = true;
  scriptElement.defer = true;
  document.body.appendChild(scriptElement);
}

With these steps, you can utilize Google API within a Blazor WASM PWA without any intermediary steps.
