A wrapper for the SmartyStreets address validation and geolocation API.
Other Python libraries exist but skip out on multiple address submission and make opinionated decisions about how to transform the return data.
.. note:: This project is not affiliated with the SmartyStreets service or company in any way.
SmartyStreets.py aims to provide a sane, tested, and feature complete wrapper to the SmartyStreets LiveAddress API, including address lookup for validation and geolocation, as well as zipcode lookup and validation.
SmartyStreets.py requires the httpx library <https://www.python-httpx.org/>
_ and will install it if it is
found missing.
pip install smartystreets.py
Create a client instance with your key::
from smartystreets import Client
client = Client(AUTH_ID, AUTH_TOKEN)
Create a client instance with SmartyStreets configuration options::
client = Client(AUTH_ID, AUTH_TOKEN, standardize=True, invalid=False,
logging=False)
These options correspond to the x-standardize-only
, x-include-invalid
, and
x-suppress-logging
headers for opening up results to standardized but not
necessarily deliverable addresses, including invalid delivery addresses, and
toggling SmartyStreets API logging, respectively.
Since the SmartyStreets API only permits up to 100 addresses to be looked up at
once the client will raise an exception if more than 100 are provided. You can
turn off this functionality using the truncate_addresses
option, which will
silently truncate the list to the first 100 addresses::
client = Client(AUTH_ID, AUTH_TOKEN, truncate_addresses=True)
Simple address lookup::
client.street_address("100 Main St Richmond, VA")
Multiple simple street addresses::
client.street_addresses(["100 Main St Richmond, VA", "100 Main St Richmond, VA"])
Note that these are different function names.
You can also use dictionaries including detailed data::
client.street_address({
'input_id': 'k1d8j',
'street': '100 Main st',
'city': 'Richmond',
'state': 'VA',
'candidates': 2,
})
And multiple detailed lookups::
client.street_addresses([
{
'input_id': 'k1d8j',
'street': '100 Main st',
'city': 'Richmond',
'state': 'VA',
'candidates': 2,
}, {
'input_id': 'z29ir',
'street': '400 Main st',
'city': 'Richmond',
'state': 'VA',
'candidates': 2,
}
])
.. note:: You cannot mix the simple street lookup style and the detailed dictionary lookup style in the same API call. This is a library restriction.
Just as important as a clean interface for working with the API is a helpful way of working with the returned data.
Returned data is presented as either a single SmartyAddress
or a
SmartyAddresses
collection. Each is based on builtin types so that you always
have access to the underlying data exactly as it was returned, but with
added convenience methods.
Address geolocation
Where is it?::
>>> address = client.street_address("100 Main St Richmond, VA")
>>> address.location
(37.5436,-77.4453)
Accuracy is subject to address inputs and available data.
Address verification
Is this a deliverable address?::
>>> address.confirmed
True
The value here does not necessarily mean this is an exact mail address (e.g. with apartment number). The SmartyStreets API will return a code indicating the complete DPV status.
Multiple addresses: input ID lookup
You can look up an address by the `input_id` parameter (provided you include
one in the request)::
>>> addresses = client.street_address([{'input_id': '123', 'street': ...}])
>>> addresses.get('123')
{'input_id': '123', 'street': ... }
The `get` method is used because the `SmartyAddresses` object's default lookup
is against the list index.
Zipcode lookup

Response errors
---------------
The following documented response codes raise specific exceptions based on a
`SmaryStreetsError` class.
- 400 Bad input. Required fields missing from input or are malformed.
- 401 Unauthorized. Addressuthentication failure; invalid credentials.
- 402 Payment required. No Addressuthenticationctive subscription found.
- 500 Internal server error. General service foundailure; retry request.
