List Admin1 Values
Discover the admin1 (state / province / oblast) values available for one country, measured over a trailing window of the settled Events table and canonicalised to exactly the tokens the admin1 filter on /api/v2/events and /api/v2/stories accepts — so discover→filter round-trips without guessing spellings. Each region appears ONCE, under whichever spelling carries the most events, with that count attached; a trailing administrative suffix (“Donetsk” vs “Donetsk Oblast”) is folded on both sides by the filter, so either spelling returns the same events. This endpoint is intentionally country-scoped and does not return the full admin1 catalog.

Query Parameters
Country to enumerate admin1 (state/province) values for — required. Accepts a country name (France), ISO-2 (FR), or ISO-3 (FRA); an unresolvable or missing value returns 400 INVALID_COUNTRY. Note: validation is owned by the endpoint service because it depends on composed or cross-parameter state; the published error semantics above still apply.
Trailing window in days (1–30) the region counts are measured over, ending today unless date moves the anchor. Both 7 and 7d are accepted. The window actually used is echoed as window_days and in applied_filters. Also accepts: window. Note: validation is owned by the endpoint service because it depends on composed or cross-parameter state; the published error semantics above still apply.
Anchor date for the window. Alone it selects that single day; combined with days it ends the trailing span on that date. Note: validation is owned by the endpoint service because it depends on composed or cross-parameter state; the published error semantics above still apply.
First day of an explicit window. May not be combined with days/window. Also accepts: start_date. Note: validation is owned by the endpoint service because it depends on composed or cross-parameter state; the published error semantics above still apply.
Last day of an explicit window. May not be combined with days/window. Also accepts: end_date. Note: validation is owned by the endpoint service because it depends on composed or cross-parameter state; the published error semantics above still apply.
