Thats the best answer. The secondary part is we want a simple way for any dev off the street to integrate with api.fraudguard.io in 5 minutes. Imagine you are a small company and you want to limit back office access to you CMS to only IPs outside of Germany. That takes just a couple minutes. Or you want to allow back office access to you CMS from everywhere but you want to decrease the session timeout to only 30 minutes if the originating IP is a tor node or public proxy, etc.
We just got out of beta (literally last night) but so far thats the majority of use cases that we've seen so far.
From a merchandising POV, you could consider moving up-market by building new more powerful features and giving them only to the $25 plan. Then, rename the plans to match who you expect to buy them. People identify with who they are more naturally than they do a number of requests per month.
Also, congrats on shipping.
Edit: Also, pre-fill the form with the visitors own IP -- or better yet just display the results?
