Oversize/Overweight Requirements Check (US)
POST a load's dimensions (width/height/length in feet+inches or decimal feet, gross weight in lbs, optional axle count) plus an origin and destination (place names or "lat,lon"), and get one LEGAL / PERMITS_REQUIRED / SUPERLOAD_REVIEW verdict for moving that oversize/overweight load, broken down per state crossed. Each state entry: whether a permit is required and which dimension triggered it, single-trip vs annual permit, the escort/pilot-car requirement (none / 1 pilot / 2 pilots / pole car / police as codified), movement/curfew restrictions, a fee estimate that ALWAYS carries a verify-with-state flag, whether a superload threshold is hit, plus the state permit-office source_url and rules_as_of date. Route states are derived from a great-circle corridor (planning-grade, not the state-assigned permitted route). Honesty is the product: this is informational planning data, NOT a permit and NOT legal advice; superloads are sent to engineering review rather than given a fake fee; states whose escort/fee specifics are not yet point-verified are flagged verify_with_state instead of guessed. State-level rules only in v1 - county/city permits, bridge engineering and low-clearance routing are out of scope and disclosed. Fail-closed before payment (dataset, geocoding and state resolution proven first); post-settle failures auto-refund.
