You're right about the pricing difference. An API is definitely something I've considered, but it opens up significant compliance and regulatory challenges - things like fraud prevention, know-your-customer requirements, and telecom regulations that are much more complex when you're providing infrastructure to other businesses rather than direct consumer services.
If you add an API, it would be a good alternative to twilio as their calling price is three times more expensive to what you’re offering.
