The same node, called by id from any surface. Every tab pins seedance-2-0-fast and passes the ports below. Full guide.

import { BlitClient } from "@blitflow/sdk";

const { runNode } = new BlitClient({ apiKey: process.env.BLITFLOW_TOKEN });

const { outputs } = await runNode("seedance-2-0-fast", {
  prompt: { value: "example" },
  firstFrame: { ref: "https://..." },
  duration: { value: 5 },
  resolution: { value: "720p" },
  aspectRatio: { value: "16:9" },
  audio: { value: true },
  seed: { value: 1 },
});
