It is ideal for multilingual or code-switching conversations requiring immediate partial results. Prefer it over batch/file transcription endpoints when the audio is live and you need word-by-word feedback, and over subscription-based STT APIs when you want anonymous, pay-per-use crypto payments with no onboarding.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T17:52:15.360Z","isFirstParty":false}
