Getting started To get started with the API, you need to obtain an API key. You can create it above on this page. To send requests to the API, use https://app.dubformer.ai as the base URL. Every API request must include an Authorization header with the value Bearer YOUR_API_KEY. Each POST request must include a Content-Type: application/json header and a request body in JSON format. You can use the Idempotency-Key header for POST requests to ensure the uniqueness of the request. Create a project for dubbing POST /api/v1/projects
