Nope, at this point, we don't take any percentage or fee. We even pass along any discounts we receive (we get up to 15% off flower some purchases for example and we pass that along to you).
Unfortunately, I don't think I could extract $25/mo out of the service myself. Do you have any plans for alternative pricing structures? I would definitely pay $100 for a block of 20 requests that I could use over the course of a year, say.
In my previous job, this was precisely the structure the firm evolved to give to certain customers who were on the fence about the service. (B2B - financial Services)
We had one tweak to it, and once people used it, they never got out.
