I'm a little new to this but my understanding is that that would be the same as doing a GET request to the REST API. Which would have the same penalty for going over 30 req/s without an OAuth token.

For example, this is what my get request to the REST endpoint looks like without URL parameters:

GET reddit.com/r/explainlikeimfive/comments/2w1xzo.json

Which returns the same response as appending .json to the the URL:
