# Introduction

> Production REST API for SeedDance video and Seedream image models.

SeedanceAPI gives you programmatic access to **SeedDance** (video) and **Seedream** (image) models through a single REST interface.

## What you get

* **Unified models** — SeedDance 2.5, 2.0, 1.x and Seedream 5.0, 4.x with consistent request shapes
* **Simple pricing** — video per second, images per generation; prepaid USD balance
* **API keys** — create `ak_...` keys in the dashboard
* **Async video jobs** — submit, poll, or receive webhooks when complete
* **Sync images** — get results in the same response
* **MCP server** — connect Cursor, Claude Desktop, and other agents at `https://api.seedanceapi.us/mcp`
