What are the differences between Analyst, Lite, Pro and Enterprise plan? What factors should I take into consideration when deciding on the plans?

The Analyst plan is well suited for those who are looking for personal use that requires a higher rate limit than what is given on the public API and exclusive access to more features. 

Meanwhile, the Lite or Pro plan will be a better option to support small to medium size projects.

For large-scale enterprise or startups with large usage volume and would require a customization plan to fit their business needs, the Enterprise plan will be the right fit.
