Per-carrier (MNO) delivery truth with silent-drop inference
Buckets outbound SMS or voice traffic by destination carrier (MCCMNC) and cross-checks the carrier-claimed delivery rate against an engagement signal (an inbound reply / a >0-second answered call within the silent-drop window) so you can spot an operator that reports delivered but never actually arrives. Use it when per-country deliverability looks clean but handsets stay quiet; the buckets array exposes silent_drop_suspected per carrier and totals aggregate the suspicion count. Restricted to owner/admin/developer/viewer; read-only, rate-limited, 60s cached.

Headers
Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.

Standard { data, meta } envelope. Per-carrier buckets (terminal/delivered/failed, delivered_with_engagement, inferred_dropped, silent_drop_suspected) sorted by volume, plus aggregate totals.
