Read active-contact usage
Requires customers:read. Active contacts this calendar month, the free-tier ceiling, and when the meter resets.
It reads the same query the bill reads — the number shown here is the number charged. Live environment only, because only live contacts count at all.
A contact becomes active for a month when a session JWT is minted for them at POST /v1/contact/token; a session issued in January and refreshed in February is active in both. The month is UTC, decided once in the schema: display may translate it, a bill may not be ambiguous.
Authorizations
A staff session token, uk_st_…. Minted by sign-up, sign-in or the two-factor exchange.
Headers
The organization the caller is acting on — the org_… code that appears in the panel URL. It identifies; the membership JOIN is what authorizes, so a forged code reads nothing. Absent, the session's default organization answers.
