Deliverability-health rollup for a contact segment
Roll the per-contact deliverability-health blend up over the segment’s materialised members on a single channel (default sms). The response carries the mean raw health of the sendable population (pre-overlay signal), the honest suppressed / opted-out counter split (the consent overlay — a healthy-but-blocked contact is a BLOCKED send, never a good send), and the reachable share of the segment, the same overlay the per-contact endpoint applies. Capped at the first-N materialised members so a 50k-member segment renders a bounded dashboard rollup.

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.
