How it works

Get Started in 3 Steps

  1. Choose a model ID

    Select a public catalog model ID and review its endpoint and current starting price.

  2. Configure RunAPI

    Set RUNAPI_API_KEY before making the endpoint request.

  3. Verify the result

    For asynchronous endpoints, poll the same endpoint until the Task reaches a terminal status.

Hermes Agent + Seedance Questions

Can I use Seedance in Hermes Agent?

Yes. Configure RunAPI as a provider in Hermes Agent, then call the Seedance endpoint shown on this page. The same API key handles chat and video generation.

Does Hermes Agent need a plugin for video generation?

No. Hermes Agent sends video requests to RunAPI the same way it sends chat requests. The endpoint accepts a JSON body and returns a task ID.

Can Hermes Agent run several Seedance generations in parallel?

Yes. Hermes Agent can submit several Seedance tasks at once with different prompts or settings, then collect the results as each one completes.

Which model ID should I use?

Choose a public model ID from the version table. Each ID exposes the endpoints shown for that version.

Does this guide configure a chat model?

No. This Model Line uses the endpoint workflow shown here and is not presented as an agent chat model.
