Singleton

OpenRouter is a singleton service -- only one connection per workspace. Agents use service: "openrouter" instead of a connection ID.

Vault API Usage

vault_execute({
  service: "openrouter",
  method: "POST",
  url: "https://openrouter.ai/api/v1/chat/completions",
  body: {
    model: "anthropic/claude-sonnet-4",
    messages: [{ role: "user", content: "Hello!" }]
  }
})

The vault automatically adds the Authorization: Bearer header.
