Request parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
model_id |
string | Required | The ID of the model to run (lumoz-tts) |
api_key |
string | Required | Your API key for authentication (sent via Bearer token in the Authorization header) |
text |
string | Required | The text or script to convert into high-fidelity speech (up to 5,000 characters). Supports bracketed performance directing tags (e.g. [whispers], [said excitedly]). |
voice_id |
string | Optional | Curated studio voice personality or custom voice ID. |
