PPCG's Unanswered Questions

Question

This dear StackExchange site has so many challenges, and so many good answers. But what about the challenges that were never answered?

Task

Write a program or a function that will print a pseudo-random open unanswered (as in, a question with exactly zero answers) challenge from PPCG. All possible challenges should be produced with the same probability.

Input

• No input will be taken.

Output

• Must only be the title, tags and the link which should be separated by newlines.
  • The title must be exactly like it is in the challenge.
  • The tags don't have a strict output format but must include all tags.
  • The link may or may not include the question-name after the question id and must lead to the challenge.
• May or may not be translated to a human readable format.
  • & to &
• Leading and trailing whitespace is allowed.

Scoring

As this is code-golf, shortest answer in bytes wins.

Answer 1

JavaScript + HTML, 271 250 232 bytes

Apparantly you can use Dates as pseudo-random numbers. I stole this from Shaggy's answer.

(Only uses about 4 of your quota)

q=[]
g=f=>fetch('//api.stackexchange.com/questions/unanswered?site=codegolf&page='+f).then(r=>r.json().then(j=>(q=[...q,...j.items])^j.has_more?g(f+1):document.write(`<pre>${(q=q[new Date%q.length]).title}
${q.tags}
`+q.link)))
g(1)

It makes an array q, then calls g(1), which fetches the first page of results and adds it to q. Then, if the request says it has_more, then it calls g(f+1), which fetches the next page, until it reaches the end and writes out to the HTML document (Which will automatically unescape the response)

If we don't care about all of the unanswered questions, just the most recent 30 (Only uses 1 of your quota):

JavaScript + HTML, 213 196 179 bytes

fetch`//api.stackexchange.com/questions/unanswered?site=codegolf`.then(r=>r.json().then(j=>document.write(`<pre>${(j=j.items[new Date%j.items.length]).title}
${j.tags}
`+j.link)))

Answer 2

Python + requests + json + random + html, 249 239 bytes

import requests as r,json,random as R,html
j=R.choice(json.loads(r.get('http://api.stackexchange.com/questions/no-answers?site=codegolf').text)['items'])
print('\n'.join([html.unescape(j['title']),'Tags: '+', '.join(j['tags']),j['link']]))

Turned out longer than I'd like.

-10 bytes thanks to @totallyhuman by using R.choice rather than R.shuffle and taking the first element.

Answer 3

Bash 255 232 bytes

a="api.stackexchange.com/questions/";b="?site=codegolf";c=$(w3m $a"unanswered"$b"&filter=total"|tr -cd 0-9);w3m $a"no-answers"$b"&pagesize=1&page="$((RANDOM%c))|jq -r ".items[0]|.title,(.tags|join(\", \")),.link"|recode html..utf-8

Looks like a wrong results returns for totals for no-answers/unanswered. General idea - get total, than get random page with one item.

Bash 174 153 bytes

w3m api.stackexchange.com/questions/no-answers?site=codegolf|jq -r ".items[$RANDOM%(.items|length)]|.title,(.tags|join(\", \")),.link"|recode html..utf-8

It select one random question from last 30, not from all questions. Works from command line. Required curl w3m, jq and recode.
