How much do Google Photorealistic 3D Tiles cost?
Google bills Photorealistic 3D Tiles per root tileset request through the Map Tiles API. The first 1,000 requests each month are free, then $6.00 per 1,000 up to 100,000, falling in tiers to $2.40 per 1,000 above 5 million. One root request opens a renderer session of up to three hours.
