# 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. Explore the sections below to learn more about using Hyperhash via direct API access. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
