pyusps -- Python bindings for the USPS Ecommerce APIs

Package Documentation

Description

pyusps is a pythonic wrapper for the USPS Ecommerce APIs. Currently, only the Address Information API is supported.

Installation

Install using pip:

pip install pyusps

or easy_install:

easy_install pyusps

Address Information API

This API is avaiable via the pyusps.address_information.verify function. It takes in the user ID given to you by the USPS and a variable length list of addresses to verify.

Requests

Each address is a dict containing the following required keys:

address:The street address
city:The city
state:The state
zip_code:The zip code in one the following formats: xxxxx, xxxxx-xxxx, or xxxxxxxxx

Only one of state or zip_code is needed.

The following keys are optional:

firm_name:The company name, e.g., XYZ Corp. Although the API documentation says this field is required, tests show that it isn't.
address_extended:
 An apartment, suite number, etc
urbanization:For Puerto Rico addresses only

Responses

The response will either be a dict, if a single address was requested, or a list of dicts, if multiple addresses were requested. Each address will always contain the following keys:

address:The street address
city:The city
state:The state
zip5:The first five numbers of the zip code
zip4:The last four numbers of the zip code

Each address can optionally contain the following keys:

firm_name:The company name, e.g., XYZ Corp.
address_extended:
 An apartment, suite number, etc
urbanization:For Puerto Rico addresses only
returntext:Additional information about the address, usually a warning, e.g., "The address you entered was found but more information is needed (such as an apartment, suite, or box number) to match to a specific address."

firm_name, address_extended and urbanization will return the value requested if the API does not find a match.

For multiple addresses, the order in which the addresses were specified in the request is preserved in the response.

Errors

A ValueError will be raised if there's a general error, e.g., invalid user id, or if a single address request generates an error. Except for a general error, multiple addresses requests do not raise errors. Instead, if one of the addresses generates an error, the ValueError object is returned along with the rest of the results.

Examples

Single address request:

from pyusps import address_information

addr = dict([
     ('address', '6406 Ivy Lane'),
     ('city', 'Greenbelt'),
     ('state', 'MD'),
     ])
address_information.verify('foo_id', addr)
dict([
    ('address', '6406 IVY LN'),
    ('city', 'GREENBELT'),
    ('state', 'MD'),
    ('zip5', '20770'),
    ('zip4', '1441'),
    ])

Mutiple addresses request:

from pyusps import address_information

addrs = [
    dict([
            ('address', '6406 Ivy Lane'),
            ('city', 'Greenbelt'),
            ('state', 'MD'),
            ]),
    dict([
            ('address', '8 Wildwood Drive'),
            ('city', 'Old Lyme'),
            ('state', 'CT'),
            ]),
   ]
address_information.verify('foo_id', *addrs)
[
 dict([
         ('address', '6406 IVY LN'),
         ('city', 'GREENBELT'),
         ('state', 'MD'),
         ('zip5', '20770'),
         ('zip4', '1441'),
         ]),
 dict([
         ('address', '8 WILDWOOD DR'),
         ('city', 'OLD LYME'),
         ('state', 'CT'),
         ('zip5', '06371'),
         ('zip4', '1844'),
         ]),
 ]

Mutiple addresses error:

from pyusps import address_information

addrs = [
    dict([
            ('address', '6406 Ivy Lane'),
            ('city', 'Greenbelt'),
            ('state', 'MD'),
            ]),
    dict([
            ('address', '8 Wildwood Drive'),
            ('city', 'Old Lyme'),
            ('state', 'NJ'),
            ]),
   ]
address_information.verify('foo_id', *addrs)
[
 dict([
         ('address', '6406 IVY LN'),
         ('city', 'GREENBELT'),
         ('state', 'MD'),
         ('zip5', '20770'),
         ('zip4', '1441'),
         ]),
 ValueError('-2147219400: Invalid City.  '),
 ]

Developing

External dependencies

  • libxml2-dev
  • libxslt1-dev
  • build-essential
  • python-dev
  • python-setuptools
  • python-virtualenv

Setup

To start developing run the following commands from the project's base directory. You can download the source from https://github.com/thelinuxkid/pyusps:

# I like to install the virtual environment in a hidden repo.
virtualenv .virtual
# I leave the magic to Ruby developers (.virtual/bin/activate)
.virtual/bin/python setup.py develop
# At this point, pyusps will already be in easy-install.pth.
# So, pip will not attempt to download it
.virtual/bin/pip install pyusps[test]

If you like to use ipython you can install it with the dev requirement:

.virtual/bin/pip install pyusps[dev]

Testing

To run the unit-tests run the following command from the project's base directory:

.virtual/bin/nosetests
