Thanks for returning my query, unfortunately the experience of incorporating even OPC/LLC varies widely between a Tier 1 city and Tier 2/3 cities or lower in India. I ran my previous startup as Pvt. Ltd. company for 5 years and much of my effort was spent on being complaint (partly because of the introduction of new Company laws, GST etc.), So you understand my apprehension, But things must have more or less settled now.

Thanks for invite, I will definitely reach out to you soon for the API.
