Literally the minute after posting this the same command above started to work. Any ideas why it would have be inoperable before?

Thanks for the heads up. Is there a reason for this? How should one retrieve an access_token programmatically in JavaScript?

Trying this with the people endpoint did work bringing back data, but it does not seem to have sent it back within a callback, just the pure JSON (eg "Uncaught SyntaxError: Unexpected token : " error, http://stackoverflow.com/questions/7936610/json-uncaught-syntaxerror-unexpected-token).

Here is the smallest test case in Angular I could come up with:

function PersonCtrl ($scope, $http, $log) {
$http.jsonp(‘https://chimera.nationbuilder.com/api/v1/people?callback=JSON_CALLBACK’, {
method: ‘GET’,
params: {
access_token: ‘ACCESS_TOKEN_HERE’
}
})
.success(function (data, status, headers, config) {
$log.log(data, status, config);
})
.error(function (data, status, headers, config) {
$log.log(data, status, config);
});
}
