I'm looking into different options for persistent online AR anchors and the pricing details for Azure Spatial Anchors are pretty clear - free up to 10,000 requests a month, then $0.02 per request.
I can't find any info on how much a similar service from Google would cost, only a quota page saying the limit is 300 read / 30 write requests per minute per user. Does anyone here have experience with either service? Would you recommend one over the other?
