[OSM-dev] API suggestion - "authorise"?

[Nick Whitelegg]

Doesn't look like you can do this at the moment but what would be good to have 
in the API is an "authorise" call which will do nothing but take a username 
and password and return either 200 OK if OK, or 401 if invalid. This would 
make it easier for client sites which use the API to perform modifications to 
add an OSM login, as the user could get instant feedback as to whether the 
login was incorrect, as opposed to waiting until they actually edit 
something.
