# Ecosystem API Reference

This is the complete reference for the Ecosystem Vendor API — the endpoints vendors use to manage paid NinjaScript add-ons and their customers. Endpoints are grouped by resource:

* **Licenses** — issue, query, and manage end-user licenses.
* **Products** — your listed products and their configuration.
* **Users** — customer accounts.
* **User Profiles** — profile details for customers.
* **Owners** — vendor/owner records.

For an introduction to the marketplace and how vendor accounts work, see the
[Marketplace overview](/marketplace).

Pick a resource in the sidebar to see its endpoints, request and response schemas, and a live playground.
