Getting Started

Overview

The Atomic Vaults Securities (AVS) API lets you integrate U.S. equities, ETFs, and listed options trading into your platform. AVS acts as a FINRA-licensed broker-dealer, handling clearing, settlement, and regulatory compliance on your behalf.

Two API environments are available:

Environment	Base URL
Trading API (UAT)	https://uat.atomicvaults.com
APAC API (UAT)	https://apac.uat.atomicvaults.com

All API requests require an X-API-KEY header. See the Authentication guide for details.
