Hello,
It has been a long time since this discussion started. I wonder if there is a chance you will reduce the price for using the API.
I understand the need for revenue and am willing to pay. But $500 a month is not a small amount. Actually, I am just thinking about it while I type, it's a larger amount than what I am paying now for a whole switch to process about a million minutes.
Many SAAS products let you use the API even with the free version, and/or scale the usage according to the price.
I think that if you come up with more creative pricing you could possibly get more revenue while providing more value to your customers/members.
As it is today, it will be cheaper to develop our own API for the price of 2-3 years, with the additional benefit of owning your own code and not being dependent on a 3rd party, if you get what I mean.
Thanks.
