I'm wondering if there is a service that to get a set of lat,long points that when connected into a polygon show the outline of a country
Ideally I would like to search by country, and get back an array of lat,long coordinates. Is there such a service?
IF you are happy to consider not using a webservice, this data is available at varying resolutions from Natural Earth. The data is in the public domain.
have a closer look here;

User:The Anome/country bounding boxes A first hack, based on all places in the NGA GNS dataset, not (yet) properly handling latitude wrap-round at ±180°. Country names are mapped from FIPS country codes. This works pretty well for all countries that do not cross the 180° meridian. Russia is a notable exception. This dataset does not include the United States.

Yahoo! GeoPlanet, the service Stack Overflow are using for their careers site seems to do bounding boxes.
Here is a blog post with detailed query examples.
This repo contains a set of square bounding boxes. Example below:
{
