It covers a single API key across platforms, shared caching, and why clean JSON beats brittle HTML parses.\n\nThe speaker contrasts fresh fetches with cache hits: the same profile call can drop from multi-second billed work to a sub-second free response. They also stress verifying per-minute Whisper billing via durationSeconds and creditsCharged in the response.\n\nClosing takeaways focus on bringing your own media files for transcript-plus-summary in one POST, and using request logs to prove cache savings.",
