# Overview

### Introduction

#### Getting Started with the Hyperhash REST API

Hyperhash provides low-level REST APIs that allow you to interact directly with wallets, user profiles, and key authorization systems. These APIs give you full control over the following core resources:

* **Users**: Create user objects with linked identities and optionally generate wallets during onboarding.
* **Wallets**: Programmatically create, manage, and interact with wallets across supported blockchains.
* **Authorization Keys**: Issue and manage authorization keys to control wallet access and permissions.
* **Policies**: Define and enforce policies that govern wallet usage and behavior.
