Meetup API
Does the API require authentication? Most Meetup API endpoints require member authentication to protect access to privacy and to personalize responses.

Does this API support CORS? yes

find/upcoming_events. The response returns a list of event objects ordered chronologically. It uses a set of parameters inculding , but not limited to,
attendence_count, .created, description, event_hosts etc...

What are the limitations on the numers of requests?  I couldn't find a specific answer. It says it will return different responses depending on 
how close you are to the limit. I saw in another document that it said the limit was 200 requests per hour and 200 max results per request.

Expected errors.
400 Bad request when there was a problem with the request
401 Unauthorized when you don't provide a valid token
429 Too Many Requests when you've gone over your request rate limit
500 Internal Server Error an unexpected error occured on our servers
