I'm trying to get the about_me data on Stack Exchange profiles via the API provided by Stack Overflow using: https://api.stackexchange.com/docs/users-by-ids.
Example:
    https://api.stackexchange.com/2.2/users/3029?&site=bitcoin
The API doesn't return the about_me profile description.
How does one get access to this? 
The about_me property is not returned by default; you must use a custom filter to get it.
For example:
    /2.2/users/1642231?site=stackoverflow&filter=!eQnjl7OMkDx5MiwVw_4HYqq7h5
Which currently returns:
"items": [ {
    "down_vote_count":  11,
    "up_vote_count":    66,
    "reputation":       7912,
    "user_id":          1642231,
    "accept_rate":      83,
    "about_me":         "<p>Stanford graduate female developer living and working...",
    "display_name":     "Patoshi パトシ"
    //etc...
