Polymarket Dataset Statistics

Instructions

Implementation Reference

• src/tools/pm.ts:267-297 (handler)

  The handler function for the 'pm_stats' tool. Calls apiGet to fetch stats from '/api/v1/pm/stats' and returns the JSON response.

  server.registerTool(
    "pm_stats",
    {
      title: "Polymarket Dataset Statistics",
      description:
        "Get statistics about the Polymarket dataset: total markets, wallets tracked, " +
        "volume, and last updated timestamp. Free endpoint.",
      inputSchema: {},
    },
    async () => {
      const res = await apiGet<PmStatsResponse>("/api/v1/pm/stats");
  
      if (!res.ok) {
        return {
          content: [
            {
              type: "text" as const,
              text: `API error (${res.status}): ${JSON.stringify(res.data)}`,
            },
          ],
          isError: true,
        };
      }
  
      return {
        content: [
          { type: "text" as const, text: JSON.stringify(res.data, null, 2) },
        ],
      };
    },
  );

• src/tools/pm.ts:269-274 (schema)

  Input/output schema for pm_stats. No input parameters (empty inputSchema). Response type defined by PmStatsResponse interface (dataset, source, update_frequency, stats).

  {
    title: "Polymarket Dataset Statistics",
    description:
      "Get statistics about the Polymarket dataset: total markets, wallets tracked, " +
      "volume, and last updated timestamp. Free endpoint.",
    inputSchema: {},

• src/tools/pm.ts:22-27 (schema)

  PmStatsResponse interface defining the shape of the stats response (dataset, source, update_frequency, stats).

  interface PmStatsResponse {
    dataset: string;
    source: string;
    update_frequency: string;
    stats: Record<string, unknown>;
  }

• src/tools/pm.ts:265-298 (registration)

  Registration of 'pm_stats' tool via server.registerTool with description stating it's a free endpoint.

    // ── Dataset stats ─────────────────────────────────────────────────────
  
    server.registerTool(
      "pm_stats",
      {
        title: "Polymarket Dataset Statistics",
        description:
          "Get statistics about the Polymarket dataset: total markets, wallets tracked, " +
          "volume, and last updated timestamp. Free endpoint.",
        inputSchema: {},
      },
      async () => {
        const res = await apiGet<PmStatsResponse>("/api/v1/pm/stats");
  
        if (!res.ok) {
          return {
            content: [
              {
                type: "text" as const,
                text: `API error (${res.status}): ${JSON.stringify(res.data)}`,
              },
            ],
            isError: true,
          };
        }
  
        return {
          content: [
            { type: "text" as const, text: JSON.stringify(res.data, null, 2) },
          ],
        };
      },
    );
  }

• src/client.ts:44-50 (helper)

  The apiGet helper function used by the pm_stats handler to make HTTP GET requests to the Verilex API.

  export async function apiGet<T = unknown>(
    path: string,
    params?: Record<string, string | number | undefined>,
  ): Promise<ApiResponse<T>> {
    const url = buildUrl(path, params);
  
    const headers: Record<string, string> = {
