TL;DR: The first complete all-sky survey in the energy range 0.75 to 30 MeV was provided by NASA's Compton Gamma-Ray Observatory (COMPTEL) as discussed by the authors, which contains firm and marginal detections of continuum and line emitting sources and presents upper limits for various types of objects.

COMPTEL gamma-ray observations of the quasars CTA 102 and 3C 454.3
J. J. Blom,H. Bloemen,K. Bennett,Werner Collmar,W. Hermsen,Mark L. McConnell,Volker Schoenfelder,J. G. Stacy,Helmut Steinle,Andrew W. Strong,C. Winkler +10 more
TL;DR: This article showed that the power-law spectra of CTA 102 and 3C 454.3 peak at 10-30 MeV energies, which is a common feature of gamma-ray AGN.
