We just recently purchased the developer business account (200k tx/month) because we needed to do less than 150k requests to the RouteMatrix API each month. Upon our first batch of calls, we found that after about 100k calls to the RouteMatrix API, it informed us we had used up our limit of transactions. When I logged into the account and went to the Transaction Report I was surprised to see that it showed we had done over 7 million geocoding transactions, but just over 100k Directions (RouteMatrix) transactions. If that is accurate, why would it have allowed so many more transactions than our limit? On the other hand, if, as we had hoped, the limit is based on the number of calls to RouteMatrix, why are we being prevented from making further calls?
