A full-featured Python client for the USPS API

pyusps - An API library for USPS, written in Python

pyUSPS is a full-featured, type annotated API client written in Python for the USPS APIs.

This library has been developed with the intention of making the USPS APIs simple and accessible to non-coders while allowing experienced coders to utilize all features the API has to offer without the boilerplate.

Features:

• 100% API Coverage. All endpoints and response models.
• Non-coder friendly. 100% annotated for full IDE auto-completion. Clients handle requests and authentication - just plug the right details in and go!
• Fully annotated. This library has a strong focus on type safety and type hinting. Models are declared and parsed using Pydantic

pyUSPS is currently in development.

Known Issues:

• As this project is still a WIP, documentation or code commentary may not always align.

Initializing the API Clients

USPS API

from pyusps import USPSAPIClient

# init client
usps_api_client = USPSAPIClient(
  # your api private key,
)

Working with Endpoints

Endpoints are 1:1 to what's available for USPS.

For more information, check out the following resources:

• USPS API Docs

Get many

# sends GET request to /company/companies endpoint
companies = usps_api_client.company.companies.get()

Get one

# sends GET request to /company/companies/{id} endpoint
accounts = usps_api_client.accounts.id("abc123").get()

Get with params

# sends GET request to /company/companies with a conditions query string
conditional_company = usps_api_client.company.companies.get(params={
  'conditions': 'company/id=250'
})

Pagination

To make working with paginated data easy, Endpoints that implement a GET response with an array also supply a paginated() method. Under the hood this wraps a GET or POST request as required, but does a lot of neat stuff to make working with pages easier.

Working with pagination

# initialize a PaginatedResponse instance for /agents, starting on page 1 with a pageSize of 100
paginated_agents = sat_api_client.agents.paginated(1,100)

# access the data from the current page using the .data field
page_one_data = paginated_agents.data

# if there's a next page, retrieve the next page worth of data
paginated_agents.get_next_page()

# if there's a previous page, retrieve the previous page worth of data
paginated_agents.get_previous_page()

# iterate over all companies on the current page
for agent in paginated_agents:
  # ... do things ...

# iterate over all companies in all pages
# this works by yielding every item on the page, then fetching the next page and continuing until there's no data left
for agent in paginated_agents.all():
  # ... do things ...

Inspiration and Stolen Code

The premise behind this came from the pyConnectWise package and I stole most of the code and adapted it to the USPS API endpoints.
