# Introduction

> Job title normalization API — convert natural language job descriptions to canonical titles or boolean search strings

## Overview

The Normalize API helps you convert natural language job descriptions into structured data:

* **Canonicalize**: Parse a job description and return the best matching canonical job title.
* **Booleanize**: Convert a job description into a boolean search string (OR/AND/NOT) for use in job boards and ATS systems.
* **Bulk operations**: Process CSV files asynchronously for large-scale normalization.

All endpoints require authentication with a Bearer API key.
