Use this endpoint to submit Veo-style long-running video-generation requests.
  • The common auth pattern is x-goog-api-key: {API_KEY}, though query-string API keys are also supported
  • This endpoint returns a long-running operation handle rather than the final video content
  • Persist the returned operation name or ID for later polling
  • You must poll /v1beta/operations/{operation_id} to track completion
