Is this the official ByteDance Seedance API?

No. ByteDance's API is billed per request and called from code. Seedance 2 is a separate service that runs the Seedance models on a credit balance and exposes them over MCP for AI assistants.

Who pays for generations?

The signed-in Seedance 2 account, from its credit balance. Failed generations are refunded automatically.

Seedance MCP server

Seedance 2 team · Updated 2026-11-10

Seedance 2 runs a remote MCP server at https://www.seedance2.net/mcp that lets any MCP client make Seedance 2.5 and Seedance 2.0 videos and AI images on the user's Seedance 2 account. It uses Streamable HTTP and OAuth 2.1 sign-in, so there is no API key to manage.
