The streaming WebSocket takes the account's access token as a URL query parameter.\n\n## Before you call either\n\n### Gladia Speech-to-Text API + MCP\n\n1. Don't resubmit a pre-recorded job after a 200 or a `transcription.created` webhook. It's already queued\n2. Pick `solaria-3` only for async EN, FR, DE, ES or IT audio. Anything live or multilingual needs `solaria-1`\n3. A 429 means the concurrency limit, 3 async and 1 live on the free plan. Wait for a running job to finish\n4. Upgrade off the free plan before sending sensitive audio\n5. Split files over 135 minutes or 1,000 MB\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`.
