Thanks! :) There are a few API-type options like Ribbit available for those who like to tinker and we actually considered using one of them first for RoboNOC. H

Thanks! :) There are a few API-type options like Ribbit available for those who like to tinker and we actually considered using one of them first for RoboNOC. However the value-add we're trying to provide is both ease of use but also redundancy and security, and so we built our own infrastructure to not be reliable on any one third party. You have a very good point on the pay-per-call. Going to pay-per-call will of course drastically change the revenue models and forecast, but is of course (or at least looks like) a better proposition for new customers. Combining per-call fees with a yearly charge might be the best of two worlds but will also need careful work to communicate effectively and not complicate things.
