vingd 0.1.3

Vingd API interface client.

Vingd enables users to pay with money or with time. Money goes directly to publishers and time is monetized indirectly through interaction with brands, content creation, loyalty, bringing new users, etc. As a result Vingd dramatically increases monetization while keeping reach. Vingd’s secret sauce are mathematical models that are adapting to each user in order to extract as much value as possible from their time.

We use vingds (think of it as “digital currency”, points, or credits) to express the value (“price”) of intangible goods (such as TV streams or newspaper articles), to reward users for their activity (time), or to authorize (“charge”) them access to digital goods.

Vingd API for Python

Vingd API enables you to register Vingd objects you’re selling, create Vingd purchase orders, verify and commit Vingd purchases. You can also reward users, either directly (in backend), or indirectly via Vingd vouchers. Detailed docs and demos are available.

Installation

To install the last stable release of Vingd API:

$ pip install vingd

Or, to install from GitHub source:

$ git clone https://github.com/vingd/vingd-api-python
$ cd vingd-api-python
$ make env && source env/bin/activate   (skip if already in virtualenv)
$ python setup.py install

Examples

Client initialization and account balance fetching:

from vingd import Vingd

VINGD_USERNAME = '[e-mail]'
VINGD_PASSWORD = '123'

# Initialize Vingd client.
v = Vingd(username=VINGD_USERNAME, password=VINGD_PASSWORD,
          endpoint=Vingd.URL_ENDPOINT_SANDBOX, frontend=Vingd.URL_FRONTEND_SANDBOX)

# Fetch user balance.
balance = v.get_user_balance()

Sell content

Wrap up Vingd order and redirect user to confirm his purchase at Vingd frontend:

# Selling details.
OBJECT_NAME = "My test object"
OBJECT_URL = "http://localhost:666/"
ORDER_PRICE = 200 # VINGD 2.00
ORDER_EXPIRES = datetime.now() + timedelta(days=1)

# Register Vingd object (once per selling item).
oid = v.create_object(OBJECT_NAME, OBJECT_URL)

# Prepare Vingd order.
order = v.create_order(oid, ORDER_PRICE, ORDER_EXPIRES)

# Order ready, redirect user to confirm his purchase at Vingd frontend.
redirect_url = order['urls']['redirect']

As user confirms his purchase on Vingd frontend he is redirected back to object URL expanded with purchase verification parameters.

# User confirmed purchase on Vingd frontend and came back to http://localhost:666/?oid=<oid>&tid=<tid>

# Verify purchase with received parameters.
purchase = v.verify_purchase(oid, tid)

# Purchase successfully verified, serve purchased content to user.
# ... content serving ...

# Content is successfully served, commit Vingd transaction.
commit = v.commit_purchase(purchase['purchaseid'], purchase['transferid'])

Reward user

Reward user with vingd:

# Vingd hashed user id, as obtained in purchase procedure (previous example).
REWARD_HUID = purchase['huid']
REWARD_AMOUNT = 75 # VINGD 0.75
REWARD_DESCRIPTION = "Testing direct rewarding"

# Reward user.
reward = v.reward_user(REWARD_HUID, REWARD_AMOUNT, REWARD_DESCRIPTION)
