Display string based on boolean

Great plugin, bravo!

With the free version, I can call https://api.twogentlemen.net/bands/190/shows and receive all information needed.

I would like to display content based on a boolean value in this style:
if (is_canceled=1) {
The show is canceled.
else {
{subloop:venue:-1}
{venue.name}, {venue.city}, {venu.country}
{/subloop:band}
}

Would be possible to query a value in the free version like this?

Best regards,
Dominique
