# Token-Based Authentication

POST https://api.deepgram.com/v1/auth/grant
Content-Type: application/json

Generates a temporary JSON Web Token (JWT) with a 30-second (by default) TTL and usage::write permission for core voice APIs, requiring an API key with Member or higher authorization. Tokens created with this endpoint will not work with the Manage APIs.

Reference: https://developers.deepgram.com/reference/auth/tokens/grant

- `ttl_seconds` (double, optional) — Time to live in seconds for the token. Defaults to 30 seconds.

## Response

### 200

Grant response

- `access_token` (string, required) — JSON Web Token (JWT)
- `expires_in` (double, optional) — Time in seconds until the JWT expires

## Errors

### 400 Bad Request Error

- `ErrorResponse`

## Types

### ErrorResponseLegacyError

- `err_code` (string, optional) — The error code
