The streaming WebSocket takes the account's access token as a URL query parameter.\n\n## Before you call either\n\n### Groq Speech-to-Text\n\n1. Send `whisper-large-v3-turbo` for transcription and `whisper-large-v3` for translation to English. The translations endpoint does not accept Turbo.\n2. Pass `url` instead of `file` for audio over 25 MB, and split anything over the plan's size limit into overlapping chunks before sending.\n3. Set `response_format` to `verbose_json` before asking for `timestamp_granularities[]`. Word timestamps add latency, segment timestamps do not.\n4. Every request is billed as at least 10 seconds of audio, so join very short clips where the task allows.\n5. Read `retry-after` on a 429 and back off. Audio limits count seconds an hour and a day as well as requests.\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, Groq Speech-to-Text or Rev AI Speech-to-Text API?\n\nGroq Speech-to-Text scores 71.8 (BB) 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 schema \u0026 documentation.\n\n### Do Groq Speech-to-Text and Rev AI Speech-to-Text API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Groq Speech-to-Text and Rev AI Speech-to-Text API without installing anything?\n\nYes. Groq Speech-to-Text has a hosted endpoint at https://api.groq.com/openai/v1 and Rev AI Speech-to-Text API at https://api.rev.ai/speechtotext/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/groq-speech-to-text-vs-rev-ai-stt.json, and with the fewest tokens: https://www.anchorterminal.com/compare/groq-speech-to-text-vs-rev-ai-stt.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"groq-speech-to-text\", \"b\": \"rev-ai-stt\"}`.
