Landexar SDKs & Libraries
First-party SDKs for JavaScript/TypeScript and Python are in active development. REST API integration is available now for any language or platform.
JavaScript / TypeScript
In DevelopmentA first-party JavaScript and TypeScript SDK for Node.js and browser environments. The SDK wraps the Landexar REST API with typed request and response models, automatic token refresh, retry logic, and pagination helpers.
The JavaScript/TypeScript SDK is in active development. REST API integration is available now — see the REST API section below.
// Future SDK usage (illustrative — not yet published)
import { LandexarClient } from '@landexar/sdk';
const client = new LandexarClient({
apiKey: process.env.LANDEXAR_API_KEY,
});
// Resolve an address to a property record
const property = await client.properties.resolve({
address: '1247 Meridian Ave, Austin, TX 78701',
});
// Query nearby development activity
const development = await client.development.nearby({
lat: property.lat,
lng: property.lng,
radiusMi: 0.5,
status: ['approved', 'permitted', 'under_construction'],
});Python
In DevelopmentA first-party Python SDK for data science, analytics, and backend integration workflows. Designed for use in Jupyter notebooks, data pipelines, and server-side applications. Includes pandas-compatible response helpers.
The Python SDK is in active development. REST API integration is available now — see the REST API section below.
# Future SDK usage (illustrative — not yet published)
from landexar import LandexarClient
client = LandexarClient(api_key=os.environ["LANDEXAR_API_KEY"])
# Resolve an address
property = client.properties.resolve(
address="1247 Meridian Ave, Austin, TX 78701"
)
# Get development activity as a DataFrame
df = client.development.nearby(
lat=property.lat,
lng=property.lng,
radius_mi=0.5,
).to_dataframe()REST API
AvailableThe Landexar REST API is the foundation for all integrations. It is a JSON API using standard HTTP methods and OAuth 2.0 bearer token authentication. Any language or platform that can make HTTP requests can integrate with Landexar.
// REST API — available now
const response = await fetch(
'https://api.landexar.com/v1/properties/resolve?address=' +
encodeURIComponent('1247 Meridian Ave, Austin, TX 78701'),
{
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Accept': 'application/json',
},
}
);
const property = await response.json();
