# Introduction

API Platform enables external applications to integrate with Oten KMS using API keys, instead of authenticating with user accounts. 

Workspace Admins manage API keys, rate limits, and API call history within their workspace.

Org Admins control organization-wide quota allocation and usage policies.

Oten KMS provides the **API Platform** feature in a **free trial** tier with the following quota limits:

<table><thead><tr><th width="63.05810546875">#</th><th>Quota</th><th>Limit</th></tr></thead><tbody><tr><td>1</td><td><strong>Max Encrypt Keys</strong></td><td><strong>200 keys / Org</strong></td></tr><tr><td>2</td><td><strong>Total API Calls</strong></td><td><strong>10,000 calls / month</strong></td></tr></tbody></table>

The 100-key limit is designed to support organizations of typical scale. Here's how keys are typically distributed across an Org:

**An Org consists of multiple Workspaces (WS).** Each Workspace may require several keys for different purposes

**Example:**

> An Org with **5 Workspaces** × \~10 keys each = **\~50 keys in use**, leaving a healthy buffer of 50 keys for future growth. If the Org scales to **10 Workspaces**, it remains within the 100-key limit.

The 100-key cap ensures sufficient flexibility for mid-sized organizations while maintaining infrastructure cost control.
