Features as GeoJSON

Filter by jurisdiction code (e.g., GA, ON, CA). Required on Free plan.

Auto-expansion: querying a state's primary code that has WZDx/CWZ or sub-state regional siblings (see GET /jurisdictions/groups) is expanded transparently to include all members. For example, ?jurisdiction=CA returns rows from CA, WZDX_CA, and 511SF.

To opt out, query a non-primary code directly (?jurisdiction=WZDX_CA returns WZDx-only rows) or pass a comma-separated list explicitly (?jurisdiction=CA,WZDX_CA), which bypasses expansion and matches each code literally.

Bounding box: minLng,minLat,maxLng,maxLat

Defaults to active-only for map rendering. active=false drops the filter and returns both active and inactive features (asymmetric vs /features for back-compat with map clients — use /features?active=false to fetch inactive-only).

Only features scheduled to start on or after this instant. Accepts an RFC3339 timestamp or a bare YYYY-MM-DD date (UTC midnight).

Matches against estimated_start_time where the source publishes a planned date, falling back to start_time otherwise. Features with no known start are excluded.

Only features scheduled to start on or before this instant. Accepts an RFC3339 timestamp or a bare YYYY-MM-DD date (UTC midnight).

Combine with ends_after to select everything whose scheduled window overlaps a period: ?starts_before=2026-09-01&ends_after=2026-08-01 returns every project active at some point during August 2026.

Only features scheduled to end on or after this instant. Accepts an RFC3339 timestamp or a bare YYYY-MM-DD date (UTC midnight).

Matches against estimated_end_time, falling back to end_time. A feature with a known start and no end is treated as open-ended and always matches. A feature with no dates at all never matches.

Only features scheduled to end on or before this instant. Accepts an RFC3339 timestamp or a bare YYYY-MM-DD date (UTC midnight).

Open-ended features (known start, no end) never match — they are not provably finished by any given date.
