# Enterprise Pricing

> Get HeyGen Enterprise API pricing for high-volume video generation. Custom rate limits, SLAs, dedicated support, and per-second billing. Contact sales.

## Overview

Enterprise plans are billed in **credits**. Credits are consumed when a video, translation, or speech job completes successfully — you are not charged for failed jobs.

Most rates are **per second of output video** (or audio) produced. The rate depends on the feature and the quality mode you select.

<Note>
  Credit balances and remaining usage are available via `GET /v3/users/me`. Contact your account team to purchase additional credits or adjust your credit pool.
</Note>

<Callout icon="⚠️">
  **OAuth vs API Key:** If you authenticate with an OAuth bearer token, usage is billed against your **web plan**, not the API tier.

  Using an **API Key** is recommended for automation and integration workflows. API key authentication provides higher concurrency limits and is more flexible and powerful for programmatic use.
