Hey,
thanks for posting the complete request.
I’m sorry if my last reply was unclearly formulated - by stating
I didn’t mean to ask for two different URLs, one containing the api-key and one not, but for a single one that contains a placeholder instead of the key or no key at all, as stated here:
As to not have your api-key exposed to the public, I have edited your reply and hidden the revision so that it no longer contains your key. As the second URL got redundant by doing so, I have removed it as well.
On to your question:
This is a common issue with rural or under-mapped regions:
I’d recommend actually choosing points that are routable to, that have some kind of path leading to them.
Best regards,
Jakob
