Instructions

Implementation Reference

• src/tools/pm_resolution.ts:159-182 (handler)

  Handler function for pm_resolution_stats: calls apiGet to /api/v1/pm/resolution/stats, handles errors, and returns JSON-formatted stats data. This is a free endpoint with no input schema.

    async () => {
      const res = await apiGet<PmResolutionStatsResponse>(
        "/api/v1/pm/resolution/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_resolution.ts:20-25 (schema)

  PmResolutionStatsResponse interface defining the response shape: dataset, source, update_frequency, and stats (Record<string, unknown>).

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

• src/tools/pm_resolution.ts:150-157 (registration)

  Registration of pm_resolution_stats tool via server.registerTool with title 'Polymarket Resolution Statistics', description explaining it returns dataset statistics (free), and empty inputSchema.

  server.registerTool(
    "pm_resolution_stats",
    {
      title: "Polymarket Resolution Statistics",
      description:
        "Get statistics about the Polymarket resolution dataset: total markets tracked, " +
        "upcoming resolutions, resolution sources, and last updated. Free endpoint.",
      inputSchema: {},

• src/index.ts:56-56 (registration)

  Top-level registration call: registerPmResolutionTools(server) invoked in the main server setup file.

  registerPmResolutionTools(server);

• src/client.ts:44-76 (helper)

  apiGet helper function used by the 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> = {
      Accept: "application/json",
      "User-Agent": "verilex-mcp-server/0.1.0",
    };
  
    // Forward x402 payment token if present in env (for paid endpoints)
    const paymentToken = process.env.VERILEX_PAYMENT_TOKEN;
    if (paymentToken) {
      headers["X-Payment-Token"] = paymentToken;
    }
  
    const res = await fetch(url, { headers });
    const data = (await res.json()) as T;
  
    const stale = res.headers.get("X-Data-Stale");
    const lastUpdated = res.headers.get("X-Data-Last-Updated");
    const ageSeconds = res.headers.get("X-Data-Age-Seconds");
  
    return {
      ok: res.ok,
      status: res.status,
      data,
      stale: stale === "true",
      lastUpdated: lastUpdated ?? undefined,
      ageSeconds: ageSeconds ? Number(ageSeconds) : undefined,
    };
  }
