SERVICE_API_KEY_ENV: dict[str, str] = {LANGSMITH_SERVICE: 'LANGSMITH_API_KEY', 'tavily': 'TAVILY_API_KEY'}Non-model services configurable via /auth, mapped to their API-key env var.
These are not LLM providers — they back features such as web search (Tavily) or
agent tracing (LangSmith) — but their credentials follow the same store-on-disk
model as model providers, so they appear in the /auth manager and can be
entered directly in the TUI instead of being exported as environment variables
before launch.
