minfraud 0.2.0

MaxMind minFraud Score and Insights API

Beta Note

This is a beta release. The API may change before the first production release.

You may find information on the changes in minFraud Score and minFraud Insights in our What’s New documentation.

Description

This package provides an API for the MaxMind minFraud Score and Insights web services.

Installation

To install the minfraud module, type:

$ pip install minfraud

If you are not able to use pip, you may also use easy_install from the source directory:

$ easy_install .

Usage

To use this API, create a new minfraud.Client object. The constructor takes your MaxMind user ID and license key:

>>> client = Client(42, 'licensekey')

The Insights service is called with the insights() method:

>>> insights = client.insights({'device': {'ip_address': '81.2.69.160'}})

The Score web service is called with the score() method:

>>> insights = client.insights({'device': {'ip_address': '81.2.69.160'}})

Each of these methods takes a dictionary representing the transaction to be sent to the web service. The structure of this dictionary should be in the format specified in the REST API documentation. The ip_address in the device sub-dictionary is required. All other fields are optional.

Assuming validation has not been disabled, before sending the transaction to the web service, the transaction dictionary structure and content will be validated. If validation fails, a minfraud.InvalidRequestError will be raised.

If the dictionary is valid, a request will be made to the web service. If the request succeeds, a model object for the service response will be returned. If the request fails, one of the errors listed below will be raised.

Errors

The possible errors are:

• minfraud.AuthenticationError - This will be raised when the server is unable to authenticate the request, e.g., if the license key or user ID is invalid.

• minfraud.InsufficientFundsError - This will be raised when your account is out of funds.

• minfraud.InvalidRequestError - This will be raised when the server rejects the request as invalid for another reason, such as a missing or reserved IP address. It is also raised if validation of the request before it is sent to the server fails.

• minfraud.HttpError - This will be raised when an unexpected HTTP error occurs such as a firewall interfering with the request to the server.

• minfraud.MinFraudError - This will be raised when some other error occurs such as unexpected content from the server. This also serves as the base class for the above errors.
