Official platform API keys

How to obtain API keys from OpenAI, Anthropic, Google Gemini, DeepSeek, MiniMax, and Moonshot, and configure them in the Mystilink Agent.

tip

Mystilink does not host models. Keys stay on your device; requests go directly to the vendor. See LLM providers.

Configure in Agent (common steps)​

In the desktop app: Settings → Models → Add model

  1. Choose Provider — pick the official template (OpenAI, Anthropic, …).
  2. Credentials — paste the API key or an env var name (e.g. OPENAI_API_KEY).
  3. (Optional) Override Base URL — only if you use a proxy gateway.
  4. Test connection — wait for success before continuing.
  5. Model ID — from suggestions or vendor docs.
  6. Display name → Save — optionally set as primary model.

If the provider is missing, create it first via New Provider using the official template.
