Regional fuel prices

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.
