U.S. Customs and Border Protection — live land-border crossing wait times for the ~82 U.S. land ports of entry on the Canadian and Mexican borders. Per crossing, the operational status / delay minutes / open-lane count for commercial-vehicle, passenger-vehicle, and pedestrian lanes, broken down by sub-lane (standard, FAST, NEXUS/SENTRI, ready). Useful for cross-border logistics, supply-chain / freight timing, and field-crew border planning. Upstream is a SINGLE bulk endpoint with no server-side filtering — this connector fetches it once (cached ~10 min) and filters/shapes the result in-process. No auth.
