Transportation-noise proximity facts

Returns straight-line distance to the nearest FAA public-use airport within 100 km, and to the nearest mapped motorway, trunk, and railway centerlines within about 3 km, for a US address or point. For agents checking transportation proximity. Distances only: no noise score, decibels, or a quiet, loud, safe, or unsafe label. Use this when you can call Locus free tools (REST tools/call or MCP). Use locus-noise-proximity instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.
