You can use font-stretch to select a stretched or stretched font among these fonts. This property has no effect if the font you are using does not provide a compressed or expanded font.

Google Fonts' user interface currently still prefers static/single-weight CSS output.

But you can manually force the API to output the @font-face rules for variable fonts:

https://fonts.googleapis.com/css2?family=Inconsolata:wdth,wght@50..200,200..900

It is important to use '..' as the range separator - otherwise you will end up with a CSS containing multiple static woff2 file URLs.

Additionally, Google's API uses some user-agent detection (also known as browser sniffing) to provide backwards compatibility (for browsers that do not support variable fonts). This makes sense... Unfortunately, this doesn't work very well: some browsers like Opera (which supports VF perfectly) also receive static fonts. (This may also work for other Chromium/Blink based browsers)

As a workaround, I recommend opening the above CSS URL in Firefox. The result should look similar to:

@font-face {
  font-family: 'Inconsolata';
  font-style: normal;
  font-weight: 200 900;
  font-stretch: 50% 200%;
  src: url(https://fonts.gstatic.com/s/inconsolata/v31/QldKNThLqRwH-OJ1UHjlKGlZ5qg.woff2) format('woff2');
}

Note that font-weight and font-stretch attribute values contain 2 values, indicating the range of weight/width. This is a good indicator that you've acquired the correct (variable) rules.

Example: Inconsolata variable font

@font-face {
  font-family: "Inconsolata";
  font-style: normal;
  font-weight: 200 900;
  font-stretch: 50% 200%;
  src: url(https://fonts.gstatic.com/s/inconsolata/v31/QldKNThLqRwH-OJ1UHjlKGlZ5qg.woff2) format("woff2");
}

body {
  font-size: 36px;
  font-family: sans-serif;
}

h2 {
  font-size: 0.5em;
  color: red;
}

p {
  font-family: Inconsolata;
  transition: 0.8s;
}

.customMap {
  font-family: sans-serif;
}

@font-face {
  font-family: "Inconsolata2";
  src: url(https://fonts.gstatic.com/s/robotocondensed/v25/ieVl2ZhZI2eCN5jzbjEETS9weq8-19K7DQ.woff2) format("woff2");
  font-stretch: 50%;
}

@font-face {
  font-family: "Inconsolata2";
  src: url(https://fonts.gstatic.com/s/roboto/v30/KFOjCnqEu92Fr1Mu51TLBCc6CsQ.woff2) format('woff2');
  font-stretch: 200%;
  font-style: normal;
  font-weight: normal;
}

.customMap {
  font-family: "Inconsolata2";
  font-style: normal;
}
