AZ511
Official REST API for Arizona DOT's 511 traveler-information system, exposing live cameras, weather stations, message signs, traffic events, alerts, and rest-area data across the state highway network. A free developer key (10 requests/60s) unlocks the core JSON/XML endpoints, while a separate no-key WZDx (Work Zone Data Exchange) GeoJSON feed publishes standardized work-zone activity for third-party consumption.
