Rate limit numbers are shown only in the console, and timestamps cannot be combined with a set language, nor diarisation with the realtime model.\n\n**Rev AI Speech-to-Text API.** Reverb English at $0.20 an hour, foreign languages at $0.30. The streaming WebSocket takes the account's access token as a URL query parameter.\n\n## Before you call either\n\n### Mistral Voxtral Transcribe\n\n1. Send `model=voxtral-mini-latest` and one of `file`, `file_url` or `file_id` as multipart form fields to `/v1/audio/transcriptions`\n2. Leave `language` out when you ask for `timestamp_granularities`, the docs say the two are not compatible\n3. Use the batch endpoint for diarisation. `voxtral-mini-transcribe-realtime-2602` does not accept `diarize`\n4. Pin `voxtral-mini-2602` if output must not change, since `-latest` aliases can move\n5. Mint browser tokens with `POST /v1/client/sessions` close to connection time and pass them in `Sec-WebSocket-Protocol`, never the API key\n\n### Rev AI Speech-to-Text API\n\n1. Keep streaming URLs out of logs. They carry `access_token`\n2. Send `source_config: {\"url\": ...}`, not `media_url`, even though the published SDKs still use `media_url`\n3. Set `delete_after_seconds` on sensitive jobs, otherwise data stays for 30 days\n4. Use `notification_config` webhooks rather than polling job status\n5. Don't build on `low_cost` or `fusion`. Both are deprecated\n\n## Questions\n\n### Which is better for AI agents, Mistral Voxtral Transcribe or Rev AI Speech-to-Text API?\n\nMistral Voxtral Transcribe scores 64.1 (B) on agent readiness against Rev AI Speech-to-Text API's 57.8 (C), and leads in 6 of 7 scored categories. Rev AI Speech-to-Text API leads on reliability.\n\n### Do Mistral Voxtral Transcribe and Rev AI Speech-to-Text API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Mistral Voxtral Transcribe and Rev AI Speech-to-Text API without installing anything?\n\nYes.
