    headers={"Authorization": "Bearer " + AIMLAPI_KEY},
    json={
      "model": "vibevoice/7b",
      "text": "Hello from AI/ML API"
    },
)
print(r.json()["audio"])  # URL to the generated audio
const r = await fetch("https://api.aimlapi.com/v1/tts", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "vibevoice/7b",
    "text": "Hello from AI/ML API"
  }),
});
const { audio } = await r.json();
console.log(audio); // URL to the generated audio
curl -X POST https://api.aimlapi.com/v1/tts \
  -H "Authorization: Bearer $AIMLAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"vibevoice/7b","text":"Hello from AI/ML API"}'

# the JSON response contains "audio" — a URL to the generated speech

OpenAI-compatible — swap the base URL and it works with your existing SDK.
