`Protected`get

get<T extends Record<string, unknown>>(
    endpoint: string,

): Promise<T>
Protected
Executes a cached, rate-limited GET request to the EP API.
Type Parameters
- T extends Record<string, unknown>
  Expected response type (extends Record<string, unknown>)
Parameters
- endpoint: string
  API endpoint path (relative to baseURL)
- Optionalparams: Record<string, unknown>
  Optional query parameters
- OptionalminimumTimeoutMs: number
  Optional per-request minimum timeout in milliseconds. When provided, the effective timeout is Math.max(minimumTimeoutMs, this.timeoutMs), so the global timeout (set via --timeout or EP_REQUEST_TIMEOUT_MS) can still extend it beyond the per-endpoint minimum. Use for known slow EP API endpoints such as procedures/feed and events/feed.
Returns Promise<T>
Promise resolving to the typed API response

On HTTP errors, network failures, or parse failures
