submit_open311_request) and track their status directly from your agent. - Collaborative Maps — List and inspect public or user-specific maps to visualize urban data.
- Appointment Management — Check availability for city services and book appointments (
book_appointment) without navigating complex web forms. - Advanced Semantic Search — Execute SPARQL queries for deep data analysis across the city's linked data infrastructure.
How it works
