Usage

import usps_tools as usps

usps_user_id = '<user id here>'

International freight:

# Create a package
package = usps.Package(
    unique_id=1,
    weight=1,
    width=1,
    length=1,
    height=1,
    value_of_contents=1,
    country='Brazil',
    origin_zip='33337',
)

# Convert to dict
package_dict = package.to_dict()

# Creating a package from dict (and validate)
try:
    package = usps.Package.get_instance(package_dict)
except usps.ValidationError as e:
    print(e.origin.messages)

try:
    package_services = usps.PriceCalculator.get_package_services(usps_user_id, package)
except usps.ConnectionFail as e:
    # Catch only connection error
    print(e)
    raise e
except usps.Timeout as e:
    # Catch only timeout connection error
    print(e)
    raise e
except usps.XmlLoadError as e:
    # Catch only xml parse error
    print(e)
    raise e
except usps.XmlResponseError as e:
    # Catch only xml response error
    print(e)
    raise e
except usps.UspsToolsException as e:
    # Catch any error
    print(e)
    raise e

if package_services.error_message:
    print(package_services.error_message)
    print(package_services.error_dict)

for service in package_services.services:
    print(service.name, service.rate)

Domestic freight:

# Create a package
package = usps.Package(
    unique_id=1,
    weight=1,
    width=1,
    length=1,
    height=1,
    value_of_contents=1,
    country='United States',
    zip_origination='33337',
    zip_destination='19716',
)

try:
    package_services = usps.PriceCalculator.get_package_services(usps_user_id, package)
except usps.UspsToolsException as e:
    # Catch any error
    print(e)
    raise e

if package_services.error_message:
    print(package_services.error_message)
    print(package_services.error_dict)

for service in package_services.services:
    print(service.name, service.rate)
