I am not giving my Credit Card details for a service that I don’t intend to incur a cost for my usage.

In addition to the Basic plan, there should be a “Free” plan that is merely like 10 calls/day (or even week or less) and has a hard limit (no extra $ for overages - just fails) and requires no CC info. Hell, it could even expire after X days and require renewal - possibly with a new key.

This would help expand usage of the API to those that are interested in playing with the service - possibly as proof of concept with no timeline for prod use - and those that don’t want to give CC info out.
