seedance

Generate and edit video with Seedance through RunAPI. Use when the user asks an agent to create, edit, or transform video with Seedance. Default to the RunAPI CLI for one-off generation; use SDKs only when the user is integrating RunAPI into an app or backend.

Seedance on RunAPI

Generate and edit video with Seedance through RunAPI. The default path for one-off agent tasks is the runapi CLI; SDKs are for application integration.

Critical: Integration Runtime

• Integration work (app, backend, worker, library, Rails service, Node service, Go service, webhook pipeline, or production codebase) uses the SDK integration path for the target language.
• One-off generation, editing, transformation, manual smoke tests, debugging, or user-requested CLI runs use the CLI path with the runapi binary. For full CLI-specific agent guidance, see https://github.com/runapi-ai/cli-skill.
• Never shell out to the runapi CLI as the production runtime integration layer.

SDK integration path

When integrating Seedance into an app, backend, worker, library, Rails service, Node service, Go service, webhook pipeline, or production workflow, start by checking the current SDK package and official usage. Confirm install commands, client methods (create, get, run), request fields, response shape, and error classes before using CLI help or raw HTTP examples. Use a RunAPI SDK package:

• JavaScript / TypeScript: @runapi.ai/seedance
• PHP: runapi-ai/seedance
• Ruby: runapi-seedance
• Go: github.com/runapi-ai/seedance-sdk/go

CLI path

The runapi binary is the one-off and manual testing runtime dependency. For full CLI-specific agent guidance, see https://github.com/runapi-ai/cli-skill. Run runapi auth status first. For agents and headless runs, prefer RUNAPI_API_KEY or import it into saved config with printf '%s' "$RUNAPI_API_KEY" | runapi auth import-token --token -. Use runapi login only when the user explicitly wants interactive browser auth.

Inspect the available commands and request fields with CLI help:

shell

runapi seedance --help
runapi seedance text-to-video --help

Run a one-off task (synchronous — polls until the task completes):

shell

runapi seedance text-to-video --input-file request.json

Submit asynchronously and poll separately:

shell

runapi seedance text-to-video --async --input-file request.json
runapi wait <task-id> --service seedance --action text-to-video

Available commands: text-to-video.

Generated file storage

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.
