RETS Python 3 Client

Python 3 client for the Real Estate Transaction Standard (RETS) Version 1.7.2. Supports Python 3.5 or later.

pip install rets-python

Example

Standard usage

>>> from rets.client import RetsClient

>>> client = RetsClient(
    login_url='http://my.rets.server/rets/login',
    username='username',
    password='password',
    # Ensure that you are using the right auth_type for this particular MLS
    # auth_type='basic',
    # Alternatively authenticate using user agent password
    # user_agent='rets-python/0.3',
    # user_agent_password=''
)

>>> resource = client.get_resource('Property')

>>> resource.key_field
'LIST_1'

>>> resource_class = resource.get_class('A')

>>> resource_class.has_key_index
True

>>> photo_object_type = resource.get_object_type('HiRes')

>>> photo_object_type.mime_type
'image/jpeg'

You can retrieve listings by performing a search query on the ResourceClass object. The results will include associated search metadata.

>>> search_result = resource_class.search(query='(LIST_87=2017-01-01+)', limit=10)

>>> search_result.count
11941

>>> search_result.max_rows
False

>>> len(search_result.data)
10

The values returned by the search query will be automatically decoded into Python builtin types.

>>> listing = search_result.data[0]

>>> listing.data
{
    'internal_listing_id': '20170104191513476022000000',
    'mls_number': '5650160',
    'mod_timestamp': datetime(2017, 8, 2, 12, 5, 17),
    'list_date': datetime(2017, 8, 2),
    'list_price': 250000,
    ...
}

>>> listing.data[listing.resource_class.resource.key_field]
'20170104191513476022000000'

Photos can also be retrieved in bulk from the ObjectType object using the resource keys of the records.

>>> all_photos = photo_object_type.get(
    resource_keys=[listing.data[listing.resource_class.resource.key_field] for listing in listings],
    location=True,
)

>>> len(all_photos)
232

>>> all_photos[0]
Object(mime_type='image/jpeg', content_id='20071218141725529770000000', description='Primary Photo', object_id='1', url='...', preferred=True, data=None)

Low level RETS HTTP client usage:

from rets.http import RetsHttpClient

client = RetsHttpClient(
    login_url='http://my.rets.server/rets/login',
    username='username',
    password='password',
    # Alternatively authenticate using user agent password
    # user_agent='rets-python/0.3',
    # user_agent_password=''
)

# Authenticate and fetch available transactions
client.login()

# See available Resources
client.get_metadata('resource')

# See available Classes for the Property resource
client.get_metadata('class', resource='Property')

# See the Table definition for Class A
client.get_metadata('table', resource='Property', class_='A')

# Get a sample of recent listings
search_result = client.search(
    resource='Property',
    class_='A',
    query='(LIST_87=2017-01-01+)',
    select='LIST_87,LIST_105,LIST_1',
    limit=10,
    count=1,
)

# Get the KeyField values of the listings
resource_keys = [r['LIST_1'] for r in search_result.data]

# Fetch the photo URLs for those recent listings
objects = client.get_object(
    resource='Property',
    object_type='HiRes',
    resource_keys=resource_keys,
    location=True,
)
