Use the exact endpoint version documented for each operation. The official API landing page is still titled “API v3,” but its maintained sections mix v3 and v4. There is no single safe /api/v3 base to apply to every resource. The REST contracts were reviewed against the live official reference on 2026-09-30, with official MCP/help pages checked through rendered extraction. Examples use illustrative identifiers and are tested offline or with mocked transport, not an authenticated account.
