Daily message volume timeline
Daily message-volume timeline for the window — one entry per day with the sent and delivered counts — as rendered by the analytics volume chart. Use ?days= (default 30, max 365) or an explicit start_date / end_date pair to select the window. Requires the advanced-analytics feature flag; otherwise returns 403.

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.
