No. That's the limit of how many queries can be made per minute on the free tier, but it doesn't state what the free tier entails or what it can be used for. My guess, based on Christian's post, is that third-party clients would not be eligible for the free tier and that the free tier is for uses like bots.

They would be eligible but they can't be useful if their allocation is just 100 requests per minute. That would be like 10 concurrent users tops. Probably even less.
