Python package providing an API client for https://github.com/ministryofjustice/postcodeinfo which contains public sector information licensed under the Open Government License v2.0

Installation

pip install postcodeinfo

Usage

Authentication

You will need an authentication token (auth token). If you’re using MOJ DS’s Postcode Info server, you can get a token by emailing platforms@digital.justice.gov.uk with a brief summary of:

  • who you are
  • what project you’re going to be using it on
  • roughly how many lookups you expect to do per day

If you’re running your own server, see https://github.com/ministryofjustice/postcodeinfo#auth_tokens for instructions on how to create a token.

Quick Start

In your code:

>>> import postcodeinfo

>>> # create a client
>>> client = postcodeinfo.Client("YOUR-ACCESS-TOKEN")

>>> # lookup a postcode
>>> postcode = client.lookup_postcode("SW1A 1AA")

>>> # postcode details
>>> postcode.valid
True

>>> postcode.latitude
51.50100893654096

>>> postcode.longitude
-0.141587558526369

>>> postcode.local_authority
{
    'gss_code': 'E09000033',
    'name': 'Westminster'
}

>>> postcode.country
{
    "name": "England",
    "gss_code": "E92000001"
}

>>> postcode.addresses
[
    {
        "uprn": "10033544614",
        "organisation_name": "BUCKINGHAM PALACE",
        "department_name": "",
        "po_box_number": "",
        "building_name": "",
        "sub_building_name": "",
        "building_number": None,
        "thoroughfare_name": "",
        "dependent_thoroughfare_name": "",
        "dependent_locality": "",
        "double_dependent_locality": "",
        "post_town": "LONDON",
        "postcode": "SW1A 1AA",
        "postcode_type": "L",
        "formatted_address": "Buckingham Palace\nLondon\nSW1A 1AA",
        "point": {
            "type": "Point",
            "coordinates": [
                -0.141587558526369,
                51.50100893654096
            ]
        }
    }
]

Configuration

Apart from the auth token, there is only one other parameter the API client needs - api_url.

Explicit api_url

You can set the api_url explicitly by passing it to the Client constructor

# create a client
client = postcodeinfo.Client("YOUR-API-TOKEN", api_url="https://some.dom.ain")

or by setting it on an existing client, like this

client = postcodeinfo.Client("YOUR-API-TOKEN")
client.api_url = "https://some.dom.ain"

Implicit api_url

If you don’t pass an api_url to the constructor, it will attempt to infer one from the environment. The client has a built-in mapping of environment names to URLs.

>>> postcodeinfo.Client.api_urls
{
    'development': 'http://localhost:8000',
    'test': 'http://localhost:8000',
    'staging': 'https://postcodeinfo-staging.dsd.io',
    'production': 'https://postcodeinfo.service.justice.gov.uk'
}

It will use the following rules to infer the URL:

  1. If you pass an env parameter to the constructor (eg: client = postcodeinfo.Client("YOUR-API-TOKEN", env="staging")), it will use that as a reference into the api_urls mapping.

  2. If you have DJANGO_SETTINGS_MODULE set in your environment, it will try to find the following settings in that module:

    POSTCODEINFO_API_URL
    POSTCODEINFO_API_TOKEN
    POSTCODEINFO_API_TIMEOUT
    
  3. Otherwise it will default to development
