# Overview

The Marketplace API — the NinjaTrader **Ecosystem Vendor API** — lets vendors manage the licensing of their paid NinjaScript add-ons and extensions programmatically. It's built for vendors; if you'd like to use the API but aren't a vendor yet, see [Authentication & Access](/marketplace/authentication) to get set up.

## What You Can Do

* **Manage products** — create and read your products and their details.
* **Issue and track licenses** — grant licenses for a product, list them, and update them (including free-trial checks).
* **Manage your vendor profile** — read and update your public user profile.
* **Manage owners** — track the users who own a product.

Most vendors start in the [NinjaTrader Ecosystem vendor portal](https://ecosystem.ninjatrader.com/) — a UI for creating products and licensing them. The Ecosystem API automates those same licensing operations so you can integrate them into your own systems.

## Get Started

1. [Authentication & Access](/marketplace/authentication) — become a vendor, get API access, and authenticate your requests.
2. Explore the endpoints in the **API** reference: Licenses, Products, User Profiles, and Owners.

> **Note**
>
> This API is separate from the trading [Trade API](/api) and [Market Data API](/market-data) — it manages Marketplace licensing, not trading or market data.
