# Seedance25API

> Independent Seedance 2.5 API guide for developers and coding agents: official API status, current EvoLink route state, documented model IDs, pricing evidence, quickstarts, and safe fallback guidance.

This is an independent Seedance 2.5 API guide. It is not the official ByteDance site.
Available in English at the paths below, Simplified Chinese under /zh, Japanese under /ja, and Korean under /ko (for example, https://seedance25api.io/ja/api and https://seedance25api.io/ko/api).

Important for agents:
- Do not fabricate API keys.
- The upstream official Seedance 2.5 API and EvoLink integration are live for the 2026-08-07 publication.
- Ask the human to create EVOLINK_API_KEY before the first live call.
- Choose the workflow-specific T2V, I2V, or R2V model ID and read the current EvoLink console price before scaling.
- Build the integration behind a configurable model parameter.
