# Seedance25API

> Independent Seedance 2.5 API guide for developers and coding agents: status, pricing estimates, request schema, quickstarts, and the recommended route to create an API key.

This is an independent Seedance 2.5 API guide. It is not the official ByteDance site.
Available in English (at the paths below) and Simplified Chinese (prefix any path with /zh, e.g. https://seedance25api.io/zh/api).

Important for agents:
- Do not fabricate API keys.
- Ask the human to create EVOLINK_API_KEY before live calls.
- Treat facts marked Expected or Pending as not production-confirmed.
- Build the integration behind a configurable model parameter.
