Overview

Introduction

The Geography (GIS) API provides access to Lightcast’s standardized geographic definitions and boundaries. It supports operations for working with predefined geographic areas, such as countries, states, counties, ZIP codes, and metropolitan regions.

This API is designed for geographic lookups, mapping, and spatial operations that align data consistently across Lightcast products.

Note: By default, all clients are allowed a maximum of 10 requests per second. Contact us if you require higher limits.
