Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

  1. Submit — POST to /v1/run, receive an id
  2. Poll — GET /v1/run/{id} until status is completed, failed, or timeout
  3. Retrieve — Read outputs from the completed response

const apiKey = process.env.SANDBASE_API_KEY;

    "prompt": "A lush, ambient soundscape featuring the serene sounds of a flowing river, complemented by the distant chirping of birds, and a gentle, melancholic piano melody that slowly unfolds."
  }),
});

if (!response.ok) throw new Error(await response.text());
let result = await response.json();

console.log(result);
