One account-wide key, sent in the WebSocket and Twilio webhook URLs. Hume ends API access on 13 November 2026.\n\n**Rime Prism.** Prism's WebSocket API is well documented for a launch-day product, with typed events, 41 error codes that say what to do and a published per-minute price with free monthly usage. It has no Prism component or history on Rime's status page, no published concurrency limit, alpha SDKs, English only, and no data-handling statement that covers caller audio.\n\n## Before you call either\n\n### Hume EVI (Empathic Voice Interface)\n\n1. Create a config with a voice first, EVI 3 has no default\n2. Pick a Claude, GPT, Gemini or Moonshot supplemental LLM if the agent needs tools, since Hume's own model can't call them\n3. Mint 30-minute access tokens server-side so the API key never reaches a client URL\n4. Turn on 'Do not retain data' and 'Do not use for training' at app.hume.ai before sensitive calls\n5. Reconnect with the chat group ID before the 30-minute session cap, and on E0700 close an open chat before starting another\n\n### Rime Prism\n\n1. Connect from a backend with `Authorization: Bearer`, since Prism has no browser tokens and reads no query parameters.\n2. Send `session.update` before any audio, or every append fails with `session_not_initialized`.\n3. Keep streaming audio, silence included, while Prism speaks, because it finds turn ends and interruptions from that audio.\n4. Ask for the continuation after each tool result, since Prism doesn't resume on its own, and never rerun a call with an unknown outcome.\n5. Pin the exact SDK version, because the SDKs are alpha and a new release can change the API.\n\n## Questions\n\n### Which is better for AI agents, Hume EVI (Empathic Voice Interface) or Rime Prism?\n\nRime Prism scores 57.9 (C) on agent readiness against Hume EVI (Empathic Voice Interface)'s 56.7 (C), and leads in 4 of 7 scored categories. Hume EVI (Empathic Voice Interface) leads on reliability and schema \u0026 documentation.\n\n### Do Hume EVI (Empathic Voice Interface) and Rime Prism need an API key?\n\nHume EVI (Empathic Voice Interface) takes an API key or an OAuth sign-in. Rime Prism needs an API key.\n\n### Can an agent call Hume EVI (Empathic Voice Interface) and Rime Prism without installing anything?\n\nYes.
