# Overview

> Start using the Paid API and SDKs to manage pricing, subscriptions, billing, and renewals.

Paid is the all-in-one, drop-in Business Engine for AI Agents that handles your pricing, subscriptions, margins, billing, and renewals with just 5 lines of code.

The Paid platform can be accessed through the API or through our SDKs.

## Prerequisites

* A [Paid account](https://app.paid.ai) and [API key](https://app.paid.ai/settings/api-keys).
* A server-side environment for requests that create or manage billing data.
* Optional: install an SDK for your language, or call the v2 API directly with bearer authentication.
