List countries with available number inventory
List every country that currently has purchasable phone-number inventory across the platform’s carriers, with the line types (local, mobile, toll_free) each can supply. Drives the country dropdown on the Buy Numbers page so a buyer only ever sees countries a search can actually fill. Inventory-truthful — a country with zero live stock never appears — aggregated across carriers (carrier names are never surfaced) and cached ~24h. Read-only; scoped on the numbers resource (numbers:read or numbers:write).

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.
