Validate Llm Connection

Validate an LLM provider API key and model availability.

Two callable shapes:

Inline - raw apiKey + optional baseUrl supplied directly, for example to test a new key before saving it.
Saved connection - savedConnectionId references a saved LLM connection; Streamkap loads its apiKey, baseUrl and provider server-side, so the stored secret never leaves the server.

Calls the provider’s free list-models endpoint to check key validity and model existence. apiKey is required unless the provider is ollama or savedConnectionId is set (422 otherwise). 404 if savedConnectionId does not match a saved connection. Per-tenant rate limit: 30 req/min -> 429 with Retry-After.
