Can we use LIRR live arrivals feed in production apps?

[Deep]

Hi,

I noticed that the MTA’s own TrainTime board at traintime.mta.info uses the following endpoint:

https://backend-unified.mylirr.org/arrivals/EMT?amtrak=true

I couldn’t find this documented at mta.info/developers.

Is this feed officially supported, and is it permitted to use in production for public-facing apps or signage?

Thanks!
