Call an API on my server from another view

So, kind of a in a weird situation here. I've got a Django project using TastyPie to power its API and some views/templates that will be used to power plugins for various sites. Rather than building this plugins as standard Django templates, I've been asked to use our API to process requests to the plugins, which means I'm calling a view on my server from another view, and for some reason that isn't working with any of my views. For reference:

#views.py
from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.template.context import Context, RequestContext
import json, urllib, urllib2

SITE_NAME = "http://localhost:8000/"
API_PATH = "api/v1/"

def aggregate(request):
    template = 'lemonwise/plugins/aggregate.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib.urlopen(url).read())['objects'][0]
    return render_to_response(template, product)

def reviews(request):
    template = 'lemonwise/plugins/reviews.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?format=json&sku=', sku])
    #Comment the next line out and the url is passed correctly
    response = urllib2.build_opener().open(url).read()
    return HttpResponse(url)
    #page = opener.open(url).read()
    #return HttpResponse(url)
    #product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    #return HttpResponse(url)
    #reviews = [json.loads(urllib.urlopen(SITE_NAME + uri)) for uri in product['reviews']]
    #return render_to_response(template, {'reviews': reviews})

def survey(request):
    template = 'lemonwise/plugins/survey.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    return render_to_response(template, product)

def mosthelpfulpositive(request):
    template = 'lemonwise/plugins/mosthelpfulpositive.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    uri = product['most_helpful_positive']
    most_helpful_positive = json.loads(urllib.urlopen(SITE_NAME + uri))
    return render_to_response(template, most_helpful_positive)

def mosthelpfulnegative(request):
    template = 'lemonwise/plugins/mosthelpfulnegative.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    uri = product['most_helpful_negative']
    most_helpful_negative = json.loads(urllib.urlopen(SITE_NAME + uri))
    return render_to_response(template, most_helpful_negative)

And the corresponding urls.py (in a different app):

#urls.py    
from django.conf import settings
from django.conf.urls.defaults import patterns, include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

from tastypie.api import Api
from lemonwise.reviews.api import *

admin.autodiscover()

v1_api = Api(api_name='v1')
v1_api.register(UserResource())
v1_api.register(MerchantResource())
v1_api.register(ProductFamilyResource())
v1_api.register(ProductResource())
v1_api.register(BooleanAttributeResource())
v1_api.register(SlideAttributeResource())
v1_api.register(ProductAttributeResource())
v1_api.register(SubmissionResource())
v1_api.register(ReviewResource())
v1_api.register(ReviewProductAttributeResource())
v1_api.register(CommentResource())
v1_api.register(BestUseResource())
v1_api.register(HelpfulVoteResource())

#Acess the api via http://127.0.0.1:8000/api/v1/user/?format=json

urlpatterns = patterns('',
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    url(r'^admin/', include(admin.site.urls)),

    # Lemonwise apps
    url(r'^reviews/', include('lemonwise.reviews.urls')),

        #API
        url(r'^api/', include(v1_api.urls)),
)

if settings.DEBUG:
    urlpatterns += staticfiles_urlpatterns()

Any idea on how to fix this? I can't find any writings on the subject.

EDIT: More specifically, what's happening is that when I load any of these views they hang trying to read the api page. ALso, my server shows no indications of any requests being processed. (Though I can load the api pages directly.)
