It has no tool-approval step, and 1.12.0 can send OPENAI_API_KEY to other OpenAI-compatible providers when no key is passed, a flaw fixed on main but not yet released.\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### Pipecat\n\n1. Pass `api_key` explicitly to every OpenAI-compatible service such as Groq, Cerebras or OpenRouter. On 1.12.0 a missing key sends `OPENAI_API_KEY` to that provider\n2. Pass `tools_filter` to `MCPClient` so only the tools the call needs reach the model, and use `tools_arguments` for values the model must not choose\n3. Gate tools that book, pay or send in your own handler. Pipecat has no approval step, and a caller's speech goes straight to the model\n4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design\n5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs\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, Pipecat or Rime Prism?\n\nPipecat scores 69.1 (B) on agent readiness against Rime Prism's 57.9 (C), and leads in 6 of 7 scored categories.\n\n### Can an agent call Pipecat and Rime Prism without installing anything?\n\nNo hosted endpoint is listed for Pipecat. Rime Prism has a hosted endpoint at wss://prism.api.rime.ai/v1/realtime.\n\n### Are Pipecat and Rime Prism open source?\n\nPipecat is open source (BSD-2-Clause for the framework. Pipecat Cloud is a hosted service under Daily's terms of service).
