300 vs Google Font API
Head-to-head usage across the sites we track.
Detections for 300 end in Jan 2021. The fingerprint catalog behind our crawls no longer carries that technology as its own entry, usually because it was retired or split into more specific ones, so its figure is the last recorded and is not directly comparable with a currently tracked technology.
