Does Google Reader have an API and if so, how can I get the count of the number of unread posts for a specific user knowing their username and password?

@GateKiller: I understand the motivation for throwing a "code-request" tag onto this... I also have an open bounty on a question where the only answer is a link to the (broken) API documentation, and it irritates me that i'll end up paying out 300 rep to someone who just Googled my keywords.

But, the tag doesn't serve any purpose. Rather, you should add a note to your actual question stating you'd appreciate sample code.

This URL will give you a count of unread posts per feed. You can then iterate over the feeds and sum up the counts.
http://www.google.com/reader/api/0/unread-count?all=true
Here is a minimalist example in Python...parsing the xml/json and summing the counts is left as an exercise for the reader:
import urllib
import urllib2
username = '[email protected]'
password = '******'
# Authenticate to obtain SID
auth_url = 'https://www.google.com/accounts/ClientLogin'
auth_req_data = urllib.urlencode({'Email': username,
'Passwd': password,
'service': 'reader'})
auth_req = urllib2.Request(auth_url, data=auth_req_data)
auth_resp = urllib2.urlopen(auth_req)
auth_resp_content = auth_resp.read()
auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x)
auth_token = auth_resp_dict["Auth"]
# Create a cookie in the header using the SID
header = {}
header['Authorization'] = 'GoogleLogin auth=%s' % auth_token
reader_base_url = 'http://www.google.com/reader/api/0/unread-count?%s'
reader_req_data = urllib.urlencode({'all': 'true',
'output': 'xml'})
reader_url = reader_base_url % (reader_req_data)
reader_req = urllib2.Request(reader_url, None, header)
reader_resp = urllib2.urlopen(reader_req)
reader_resp_content = reader_resp.read()
print reader_resp_content

Here is an update to this answer
import urllib
import urllib2
username = '[email protected]'
password = '******'
# Authenticate to obtain Auth
auth_url = 'https://www.google.com/accounts/ClientLogin'
#auth_req_data = urllib.urlencode({'Email': username,
# 'Passwd': password})
auth_req_data = urllib.urlencode({'Email': username,
'Passwd': password,
'service': 'reader'})
auth_req = urllib2.Request(auth_url, data=auth_req_data)
auth_resp = urllib2.urlopen(auth_req)
auth_resp_content = auth_resp.read()
auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x)
# SID = auth_resp_dict["SID"]
AUTH = auth_resp_dict["Auth"]
# Create a cookie in the header using the Auth
header = {}
#header['Cookie'] = 'Name=SID;SID=%s;Domain=.google.com;Path=/;Expires=160000000000' % SID
header['Authorization'] = 'GoogleLogin auth=%s' % AUTH
reader_base_url = 'http://www.google.com/reader/api/0/unread-count?%s'
reader_req_data = urllib.urlencode({'all': 'true',
'output': 'xml'})
reader_url = reader_base_url % (reader_req_data)
reader_req = urllib2.Request(reader_url, None, header)
reader_resp = urllib2.urlopen(reader_req)
reader_resp_content = reader_resp.read()
print reader_resp_content
Google Reader removed SID auth around June, 2010 (I think), using new Auth from ClientLogin is the new way and it's a bit simpler (header is shorter). You will have to add service in data for requesting Auth, I noticed no Auth returned if you don't send the service=reader.
You can read more about the change of authentication method in this thread.
