Instructions

Implementation Reference

• src/index.ts:1675-1693 (registration)

  Registration of the 'get_hip4_trades_recent' tool. It defines input schema (coin + optional limit), uses ListOutputSchema, and calls the REST API at `/trades/{coin}/recent`.

  // HIP-4 Recent Trades
  registerTool(
    "get_hip4_trades_recent",
    "Get the most recent HIP-4 trades for a coin (e.g. '0'). Bare numeric coins are canonical; legacy '#0' / '%230' forms are also accepted.Returns the latest trades without needing a time range.",
    {
      coin: Hip4CoinParam,
      limit: LimitParam,
    },
    ListOutputSchema,
    async (params) => {
      const q: Record<string, unknown> = {};
      if (params.limit) q.limit = resolveLimit(params.limit);
      const result = await hip4Request(
        `/trades/${normalizeHip4Coin(params.coin)}/recent`,
        q
      );
      return formatResponse(result.data);
    }
  );

• src/index.ts:1684-1692 (handler)

  Handler function for get_hip4_trades_recent. Builds a query object with an optional limit, calls hip4Request to GET `/trades/{normalizedCoin}/recent`, and returns the response data.

  async (params) => {
    const q: Record<string, unknown> = {};
    if (params.limit) q.limit = resolveLimit(params.limit);
    const result = await hip4Request(
      `/trades/${normalizeHip4Coin(params.coin)}/recent`,
      q
    );
    return formatResponse(result.data);
  }

• src/index.ts:1679-1683 (schema)

  Input schema for get_hip4_trades_recent: coin (HIP-4 coin symbol) and optional limit. Output schema is ListOutputSchema (records, count, nextCursor).

  {
    coin: Hip4CoinParam,
    limit: LimitParam,
  },
  ListOutputSchema,

• src/index.ts:1487-1537 (helper)

  Helper function hip4Request that sends GET requests to the HIP-4 REST API path. Used by get_hip4_trades_recent to call `/trades/{coin}/recent`.

  async function hip4Request(
    path: string,
    query?: Record<string, unknown>
  ): Promise<{ data: unknown; nextCursor?: string }> {
    const url = new URL(`${HIP4_BASE_PATH}${path}`, HIP4_BASE_URL);
    if (query) {
      for (const [k, v] of Object.entries(query)) {
        if (v === undefined || v === null) continue;
        url.searchParams.set(k, String(v));
      }
    }
    const headers: Record<string, string> = {
      "Content-Type": "application/json",
      "User-Agent": "0xarchive-mcp/1.9.0",
    };
    if (apiKey) headers["X-API-Key"] = apiKey;
  
    const controller = new AbortController();
    const timeout = setTimeout(() => controller.abort(), 60000);
    try {
      const response = await fetch(url.toString(), {
        method: "GET",
        headers,
        signal: controller.signal,
      });
      const text = await response.text();
      let body: any;
      try {
        body = text ? JSON.parse(text) : null;
      } catch {
        body = text;
      }
      if (!response.ok) {
        const requestId =
          response.headers.get("x-request-id") || body?.meta?.requestId;
        const message =
          (body && (body.error?.message || body.error || body.message)) ||
          `HTTP ${response.status}`;
        throw new OxArchiveError(message, response.status, requestId ?? undefined);
      }
      if (body && typeof body === "object" && "data" in body) {
        return {
          data: body.data,
          nextCursor: body.meta?.nextCursor,
        };
      }
      return { data: body };
    } finally {
      clearTimeout(timeout);
    }

• src/index.ts:307-314 (helper)

  Normalization helper for HIP-4 coin symbols. Strips legacy '#' / '%23' prefixes to canonical bare numeric form.

  function normalizeHip4Coin(coin: string): string {
    const trimmed = String(coin).trim();
    if (/^\d+$/.test(trimmed)) return trimmed;
    const stripped = trimmed.replace(/^(#|%23)/i, "");
    if (/^\d+$/.test(stripped)) return stripped;
    // Unknown shape — fall back to URL-encoding the original.
    return encodeURIComponent(trimmed);
  }
