# GlobalAI OPC: AI Video, Image, and Text API Gateway

> Access video, image, and text AI generation through a unified OpenAI-compatible API. Supports Sora, VEO, Seedance, Vidu, Grok, GPT, Claude, and Gemini.

GlobalAI OPC is a unified API gateway that gives you access to the world's leading AI generation models — including Sora, VEO, Seedance, Vidu, Grok, GPT Image, Claude, and Gemini — through a single, OpenAI-compatible interface. Generate videos, images, and text with one API key and a consistent request format.

## How It Works

<Steps>
  <Step title="Get your API key">
    Contact us to obtain your API key. Store it securely — you'll use it for every request.
  </Step>

  <Step title="Choose a model">
    Select from video, image, or text generation models. Each model family has tiers for different speed and quality needs.
  </Step>

  <Step title="Submit a generation task">
    Send a POST request with your prompt and parameters. You'll receive a task ID immediately.
  </Step>

  <Step title="Poll for results">
    Use the task ID to query the result endpoint until your generation is complete, then download the output.
  </Step>
</Steps>

<Note>
  Video and image generation uses an asynchronous task model. After you submit a request, poll the result endpoint every 30–60 seconds until the task status changes to `completed`. See [Async Tasks](/guides/async-tasks) for details.
