I wonder how much putting a CDN in front of this would reduce this.

According to the readme, it seems like the bulk of the traffic is highly cacheable, so presumably you could park something a CDN in front and substantially reduce the bandwidth requirements.

Yes, the static-ct api is designed to be highly cacheable by a CDN.

That is one of the primary motivations of its design over the previous CT API, which had some relatively flexible requests that led to less good caching.
