 Building data APIs provide a powerful way to access structured information about physical locations, properties, and addresses. In this tutorial, we will walk through the fundamentals of integrating with the Building Data API suite.

## Prerequisites

Before you begin, make sure you have an active API key from the DevPortal dashboard. You will also need a basic understanding of RESTful API concepts and JSON data formats.

## Making Your First Request

The simplest way to get started is with an address lookup query. Send a GET request to the /v2/buildings/lookup endpoint with the address as a query parameter. The API will return structured building data including property type, square footage, year built, and geographic coordinates.

## Validating Addresses

Address validation is crucial for data quality. Our Address Validation API normalizes input addresses, corrects common errors, and returns a confidence score. Use the /v2/addresses/validate endpoint to verify addresses before storing them in your database.

## Enriching Location Records

Once you have validated addresses, you can enrich your records with additional data points such as building characteristics, zoning information, and nearby amenities. The enrichment endpoint supports batch processing for high-volume use cases.
