The stated ratios let me check it. An hour of audio is about 30,000 output tokens, which is $0.645 at the audio rate, so the remaining few cents is text and the estimate holds up. No free credit has been found for new accounts. Each request or stream stops at 2 minutes of audio and truncates past that, and billing for truncated or failed requests is unchecked, so I can't say whether a cut-off request is paid for in full. Three because the rate is low and checkable, but an unfunded account can't test it and the truncation rule is missing.

Defaults are 3 concurrent requests and 100 requests a minute, raisable in the console. Low, but written down, so I mark it down once. A 429 returns `limit_exceeded` with advice to slow down, and no backoff pattern or Retry-After. Errors carry machine-readable `error_type` values, which is the good part. The Instatus page splits TTS REST and real-time across US, EU, Japan and India. It shows 100 per cent over 90 days and no TTS incident, but the history starts in August, so it says little about the full quarter. The three incidents on record hit STT and the console. No millisecond latency figure, no SLA, nothing on billing for truncated calls. Three, for a clear limits page and thin retry guidance.
