The public API uses API keys for authentication.
API Key
Section titled “API Key”Send your API key in the Authorization header with every request.
Authorization: Bearer <api key>Keep API keys private and call the API from trusted server-side code whenever possible.
Idempotency
Section titled “Idempotency”Idempotency-Key is optional. Use it when creating a transcription task if your client may retry the same request.
When the same key is used with the same request body, repeated requests return the original response and include meta.idempotentReplayed: true. Reusing the same key with a different request body returns a conflict error.
