Depending on what you’re trying to do, the store does expose that information (and snapd does use it, but does not expose it) via the snap-yaml field. It has some caveats but, for example, you can do
http https://api.snapcraft.io/v2/snaps/info/emoj \
Snap-Device-Series:16 architecture==amd64 fields==snap-yaml |
jq -r '."channel-map"[0]."snap-yaml"'
which produces
