Transaction Hash Search Query for Celestia explorers Guru.

[shassal]

Hi Team,

I am trying this API:
https://celestia.explorers.guru/_next/data/qSy2K47RdKSOxsnH-xDTn/transaction/89054D477BB7E10AE015BD6D2A58C607EAC1A4214816586CD7EC09A2F8BC60AE.json?hash=89054D477BB7E10AE015BD6D2A58C607EAC1A4214816586CD7EC09A2F8BC60AE

To get the transaction details for this particular hash: 89054D477BB7E10AE015BD6D2A58C607EAC1A4214816586CD7EC09A2F8BC60AE
On this explorer:
https://celestia.explorers.guru/

Everything is working fine but just curious that [qSy2K47RdKSOxsnH-xDTn] this thing that is present in the API url.

Is this system generated or we can get that? If yes, from where and in how many days will it expire?

Any help would be appreciated.

Thanks :)
