# Introduction

> Critical climate and environmental risk data for any U.S. location.

The AreaHub API connects you to AreaHub’s industry-leading Environmental Intelligence+™ - high-quality, standardized climate and environmental risk data for a single point or multiple points on the map. Send coordinates, receive risk ratings or nearby-hazard counts across 37 topics — wildfire, flood, brownfields, superfund sites, power plants, air quality, and much more.

It’s built for teams doing property-level risk assessments or property management - from due diligence, insurance underwriting, and portfolio screening to investment analysis, operational decision making, and resilience planning - to help reduce unnecessary losses and protect long-term value.

## How it works

Every request is a location lookup. There are three ways to ask:

## Topic categories

AreaHub API’s 37 topics are categorized into three groups. **Each group returns a different shape** — this is the most important thing to understand before you integrate.

| Category     | Topics | `value` returns                                                                                                             |
| ------------ | ------ | --------------------------------------------------------------------------------------------------------------------------- |
| Natural      | 18     | An object with a risk rating                                                                                                |
| Proximity    | 14     | A number — the count of those items within the relevant topic in a set radius of the location “resulting sum of the object” |
| Measurements | 5      | An object specific to that measurement                                                                                      |

See the [Topics Reference](/reference/topics) for the exact return shape of every topic.
