API and Technology

Access Landexar property intelligence programmatically — integrate parcel data, zoning, development activity, and infrastructure records directly into your applications and workflows.

Building With Landexar Data

The Landexar API makes property intelligence data available programmatically — enabling developers to integrate parcel records, zoning data, development activity, and infrastructure project information into their own applications, workflows, and analytical tools.

Common use cases include: enriching property records in CRM systems with zoning and development context; building custom dashboards that monitor development activity in specific markets; automating alerts when new permits are issued or project statuses change; and integrating Landexar data into underwriting or due diligence workflows.

Full API documentation, authentication guides, and code examples are available in the Landexar developer portal. API access is available on Professional and Enterprise plans.

Key Concepts

REST API

A web API that uses standard HTTP methods (GET, POST, PUT, DELETE) and returns data in JSON format. Landexar exposes property intelligence data through a REST API.

API Key

A credential used to authenticate requests to an API. Landexar API keys are associated with a specific account and plan tier.

Rate Limiting

A restriction on the number of API requests that can be made within a given time period. Rate limits vary by plan tier.

Webhook

A mechanism for receiving real-time notifications when data changes — for example, when a development project status is updated or a new permit is issued.

GeoJSON

A standard format for encoding geographic data structures in JSON. Landexar returns parcel boundaries and other spatial data in GeoJSON format.

Pagination

A technique for returning large datasets in manageable chunks. Landexar API responses for list endpoints use cursor-based pagination.
