If you're looking for the $10.00 answer, look elsewhere. The present answer is the $0.02 one.
The tell-tale sign that a road bike is an endurance road bike is that it will have a long head tube.
Likewise, seeing a short head tube on a showroom floor means you're looking at a racing road bike.
This does not help you in the absolute, because a size XL, 61 cm, or similar racing bike will still have a sizeable head tube. But if you look only at medium, or 54 cm, frames, you should clearly see the difference between an endurance and a racing road bike. At some point (medium? small?) the head tube on a true racing bike will be so small it will seem that the top tube and the down tube meet nearly at a point.
Why "should"? Because there are too many bike builders, and there is no formal definition for what constitutes one type or another of bike. You may find in the details "this bike is intended to blur the lines between an endurance and a racing bike", despite that the heading declared as one type or another at the outset. You're then on your own determining whether it's closer to this or that.
The longer head tube will mean that your posture will be more upright. The smaller head tube means your back is arched quite steeply. It may be a more aerodynamic position, but it's not the most comfortable to maintain for a long day.
This answer is work-in-progress. Determining the type of the bike in the question is only possible if we: 1- determine whether it is "medium", and 2- compare its head tube, as one litmus test, with other bikes of the same or similar size. In other words, the conclusion is in general not a Boolean "endurance" or "racing". It lies in general on a continuum.
