  }),
})
const job = await res.json() // { id: "job_…", status: "queued" }

Python

import os
import requests

headers = {"Authorization": f"Bearer {os.environ['VARG_API_KEY']}"}

job = requests.post(
    "https://api.varg.ai/v2/tools/music/call",
    headers=headers,
    json={
      "model": "mureka_8",
      "prompt": "A bright summer love song with a catchy chorus",

    },
).json()  # {"id": "job_…", "status": "queued"}

GET /v2/jobs/{id}

curl https://api.varg.ai/v2/jobs/$JOB_ID \

# Poll until "status" is completed, failed or cancelled.

}
console.log(current.output?.outputs?.[0]?.url)

Python

import time

while job["status"] not in ("completed", "failed", "cancelled"):
    time.sleep(3)
    job = requests.get(f"https://api.varg.ai/v2/jobs/{job['id']}", headers=headers).json()

print(job["output"]["outputs"][0]["url"])
