Get Started

What you need

• API Key: Sign up at map.arohon.co to get your key. All requests require Authorization: Bearer YOUR_API_KEY
• MapLibre GL JS: v4.x recommended for maps (e.g. maplibre-gl@4.7.1)
• Coordinates: Use lat,lng for API params (e.g. origin=23.81,90.41)

Authentication

All API requests (except /health) require the Bearer token header:

Authorization: Bearer YOUR_API_KEY

Polyline Format

Route polylines use Valhalla polyline6 (6 decimal precision). Use factor 1e6 when decoding:

function decodePolyline(str) {
  const factor = 1e6;
  const coords = [];
  let i = 0, lat = 0, lng = 0;
  while (i < str.length) {
    let b, shift = 0, result = 0;
    do { b = str.charCodeAt(i++) - 63; result |= (b & 0x1f) << shift; shift += 5; } while (b >= 0x20);
    const dlat = (result & 1) ? ~(result >> 1) : (result >> 1);
    result = 0; shift = 0;
    do { b = str.charCodeAt(i++) - 63; result |= (b & 0x1f) << shift; shift += 5; } while (b >= 0x20);
    const dlng = (result & 1) ? ~(result >> 1) : (result >> 1);
    lat += dlat; lng += dlng;
    coords.push([lng / factor, lat / factor]);
  }
  return coords;
}
