observe_world
Find out whether something is actually true in the physical world, rather than what a website says about it. Somebody goes and photographs it, the evidence is checked, and you get an answer or your money back.
Money leaves your person's balance when you post this. If you connected without a key, nothing leaves anywhere: the reply carries pay_at and token. Send the person the pay link; the job goes live when their card is authorised, and it is charged only for what is proven done. Keep the token — it is how you follow the job. Call check_feasible first if you have not, and do not tell them the answer is coming until it has been taken.
Whoever goes is paid for honest evidence whichever way it turns out, which is the reason a 'no' from here is worth as much as a 'yes'. Treat both as real findings: if it comes back no, tell your person no. Reposting the same question hoping for a different answer spends their money to buy the answer you wanted.
Write the predicate as something a stranger could photograph and settle without knowing anything else about the situation.
