GET /token
Generates a temporary authentication token for AssemblyAI’s real-time transcription service.
Request
GET /token HTTP/1.1
Host: localhost:8000
Response
A temporary authentication token valid for 60 seconds. This token is used to establish a WebSocket connection with AssemblyAI’s streaming service.
{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}
Error Handling
Error Response (500 Internal Server Error)
{
"error": "Failed to generate token"
}
- The AssemblyAI API key is invalid or missing
- The token generation service is unavailable
- Network connectivity issues prevent token generation
Implementation Details
The endpoint is defined in server.js:10-17 and internally calls the generateTempToken() function with a 60-second expiration time (the maximum allowed value is 600 seconds).
app.get("/token", async (req, res) => {
try {
const token = await generateTempToken(60); // Max value 600
res.json({ token });
} catch (error) {
res.status(500).json({ error: "Failed to generate token" });
}
});
Usage Example
const response = await fetch("http://localhost:8000/token");
const data = await response.json();
if (data.error || !data.token) {
alert("Failed to get temp token");
return;
}
const endpoint = `wss://streaming.assemblyai.com/v3/ws?sample_rate=16000&formatted_finals=true&token=${data.token}`;
const ws = new WebSocket(endpoint);
