Implementation Reference

• src/index.ts:295-306 (handler)

  The 'get_markets' tool handler - calls the API endpoint '/markets' to retrieve all available trading markets and returns the data as JSON text. Takes no input parameters.

  // Tool: get_markets
  server.tool(
    "get_markets",
    "List all available trading markets with their symbol info.",
    {},
    async () => {
      const data = await apiGet<unknown[]>("/markets");
      return {
        content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }],
      };
    }
  );

• src/index.ts:91-100 (helper)

  Helper function used by get_markets to make authenticated GET requests to the API. Constructs the full URL from API_BASE and path, adds auth headers, and parses the JSON response.

  async function apiGet<T>(path: string): Promise<T> {
    const res = await fetch(`${API_BASE}${path}`, {
      headers: getAuthHeaders(),
    });
    if (!res.ok) {
      const text = await res.text();
      throw new Error(`API GET ${path} failed (${res.status}): ${text}`);
    }
    return res.json() as Promise<T>;
  }
