WFRMLS Python Client

A comprehensive Python wrapper for the Wasatch Front Regional MLS (WFRMLS) API, providing easy access to all RESO-certified endpoints.

Release Note

property.get_property() now returns one normalized response shape: a single property dictionary. If the upstream API responds with an OData wrapper such as {"value": [...]}, the library unwraps it internally so callers can always read fields like ParcelNumber directly from the returned property object.

⚠️ Important Notice

Media, History, and Green Verification endpoints are currently unavailable due to server-side issues (504 Gateway Timeouts and missing entity types). These features have been temporarily disabled until the server issues are resolved.

🚀 Quick Start

from wfrmls import WFRMLSClient

# Initialize client with bearer token
client = WFRMLSClient(bearer_token="your_bearer_token")

# Or use environment variable WFRMLS_BEARER_TOKEN
client = WFRMLSClient()

# Get active properties
properties = client.property.get_properties(
    top=10,
    filter_query="StandardStatus eq 'Active'"
)

# Get property details
property_detail = client.property.get_property("12345678")
print(property_detail["ParcelNumber"])

# Get member information
members = client.member.get_active_members(top=10)

# Get office information
offices = client.office.get_active_offices(top=10)

📦 Installation

pip install wfrmls

🔧 Setup

Environment Variables

🔍 Advanced Features

OData Query Support

# Field selection
properties = client.property.get_properties(
    select=["ListingId", "ListPrice", "StandardStatus"],
    top=50
)

# Complex filtering
properties = client.property.get_properties(
    filter_query="ListPrice ge 200000 and ListPrice le 500000 and StandardStatus eq 'Active'",
    orderby="ListPrice desc"
)

# Include related data
properties = client.property.get_properties(
    expand=["Media", "Member"],
    top=25
)

Geolocation Search

# Search within radius (miles)
properties = client.property.search_properties_by_radius(
    latitude=40.7608,  # Salt Lake City
    longitude=-111.8910,
    radius_miles=10,
    additional_filters="StandardStatus eq 'Active'"
)

# Search within polygon area
polygon = [
    {"lat": 40.7608, "lng": -111.8910},
    {"lat": 40.7708, "lng": -111.8810},
    {"lat": 40.7508, "lng": -111.8710},
    {"lat": 40.7608, "lng": -111.8910}  # Close polygon
]

properties = client.property.search_properties_by_polygon(
    polygon_coordinates=polygon,
    additional_filters="PropertyType eq 'Residential'"
)

Data Synchronization

from datetime import datetime, timedelta

# Get incremental updates (recommended every 15 minutes)
cutoff_time = datetime.utcnow() - timedelta(minutes=15)
updates = client.property.get_properties(
    filter_query=f"ModificationTimestamp gt {cutoff_time.isoformat()}Z"
)

# Track deletions for data integrity
deleted_records = client.deleted.get_deleted(
    filter_query="ResourceName eq 'Property'"
)

🏗️ Architecture

The client follows a modular architecture with service separation:

WFRMLSClient
├── property          # Property listings
├── member           # Real estate agents  
├── office           # Brokerages/offices
├── openhouse        # Open house events
├── lookup           # Lookup tables
├── adu              # Accessory Dwelling Units
├── deleted          # Deletion tracking
└── data_system      # API metadata

Note: Media, History, and Green Verification clients are currently disabled due to server-side issues.

⚠️ Error Handling

from wfrmls.exceptions import (
    WFRMLSError, 
    AuthenticationError, 
    NotFoundError, 
    RateLimitError
)

try:
    property_data = client.property.get_property("12345678")
    print(property_data["ParcelNumber"])
except NotFoundError:
    print("Property not found")
except RateLimitError:
    print("Rate limit exceeded - wait before retrying")  
except AuthenticationError:
    print("Invalid bearer token")
except WFRMLSError as e:
    print(f"API error: {e}")

client.property.get_property(listing_id) returns a single property dictionary, not an OData wrapper. Fields such as ParcelNumber, ListPrice, and UnparsedAddress are top-level keys on the returned object. Missing listings raise NotFoundError.

📊 Utah Grid Address System

The API supports Utah's unique grid address system:

# Standard address: "123 Main Street"
# Grid address: "1300 E 9400 S"

# Grid addresses are automatically detected and handled
properties = client.property.get_properties(
    filter_query="StreetName eq '9400 S'"
)

🚦 Rate Limits

• 200 records per request maximum
• 15-minute recommended update frequency for data sync
• Use NextLink pagination for large datasets (more efficient than $skip)
