  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.
