Public Camera Feed Health & Uptime - Liveness Oracle for DOT / Transit Networks

Near-real-time operational health for publicly operated roadway and transit cameras across 24 government networks (US, Canada, UK, Finland). Per camera: a liveness state (live / degraded / dead) with a confidence score and reason code, plus a per-network rollup of totals, live/dead counts, and 24-hour uptime - keyed to the same stable source ids as the Public Camera Registry. Use it to monitor public-camera uptime across agencies, detect outages and degraded feeds, build data-quality SLAs over third-party camera networks, or filter to only-live cameras before downstream processing. Free tier. Derived status only - no raw video or imagery.
