description: 'Gladia is an AI audio infrastructure platform that offers speech-to-text transcription via both REST and WebSocket
  APIs, supporting asynchronous pre-recorded audio processing and real-time live transcription. The platform provides speaker
  diarization, automatic language detection across 100+ languages, word-level timestamps, and audio intelligence features
  powered by large language models. Authentication uses an API key passed via the x-gladia-key HTTP header against the base
  URL https://api.gladia.io/v2/. Gladia offers a free tier with 10 hours per month, metered paid plans starting at $0.61/hour
  for async and $0.75/hour for real-time, and custom enterprise pricing with zero data retention and SLA guarantees.
