Rishi: Traditional: associated with the Yājñavalkya transmission of the Vājasaneyins (individual ṛṣi attribution not explicit in the provided excerpt).
Devata: Agni (as mediator to ‘the Gods’).
Chandas: Mixed/prose-like yajus-formula with ṛgvedic cadence; treated liturgically as Yajus (not primarily metrical in performance).
We, even to-day, have rendered unto thee our desire; with hands outstretched, having approached with reverence. With a mind most apt for sacrifice do thou worship the Gods; with thought unflagging, O inspired Agni!
