It allows an application to lock a specific row in a database table to prevent concurrent access issues such as write-write conflicts, dirty reads, and lost updates.

When this endpoint is called, it will typically require an identifier for the specific row that should be locked, possibly a user session or transaction id, and maybe a time-out specification to prevent indefinite locks.
