BINGO! I was using the wrong coordinate type. I was in JROTC and we learned about the Universal Transverse Mercator system, shooting a bearing and all that rot, but it's been a very long time. So apparently you need to use the d.ddd d.ddd system and not the one I was using which was, NS d.ddd EW d.ddd
So with that bit of Info. perhaps it would be prudent to add some verbiage there in that entry search box that all coordinates need to be in d.ddd d.ddd decimal format?
I guess I was using decimal format, but it also uses East and West.
So if you use the wrong coordinate the API throws an error. That may come across to a user that the system is broken or something. Especially when you see this above the search box:
Latitude (N)
Longitude (W)
Note the N and W.
I hate WYSWYG editors...
