What “Beta” means for ElevenLabs Conversational AI
The integration path is built and tested. Real customers can attach now, but expect minor breaking changes until the 1.0 contract freeze.
How it attaches
LLM proxy.
Point ElevenLabs Conversational AI's model base URL at the Trustvice proxy. Trustvice records the full request + response and forwards to the real provider; streaming is preserved.
Replace your agent's LLM base URL with the Trustvice proxy URL. Trustvice captures the request and forwards to the real provider.
- 1
Pick an auth mode
Workspace-key mode: send Authorization: Bearer twk_… and let Trustvice attach your stored provider credentials. Passthrough mode: send your real provider key and add X-Trustvice-Workspace for routing.
- 2
Change the base URL
Set `the agent's "Custom LLM" → Server URL field (with Model ID + an API key)` to the matching Trustvice proxy URL (…/api/proxy/openai, …/api/proxy/anthropic, or …/api/proxy/gemini). ElevenLabs Conversational AI speaks the OpenAI-compatible wire format, so use the matching proxy path.
- 3
Verify
The first request through the proxy shows up immediately in Witness. The synchronous path adds ≤50 ms; capture happens asynchronously after the response is returned.
