get_hip4_trades

Instructions

Implementation Reference

• src/index.ts:1659-1673 (registration)

  Tool 'get_hip4_trades' registration using registerTool. Defines input schema (coin with Hip4CoinParam + HistoryParams), output schema (ListOutputSchema), and the handler that calls hip4Request to GET /trades/{coin} with query params.

  // HIP-4 Trades
  registerTool(
    "get_hip4_trades",
    "Get HIP-4 trade/fill history for a coin (e.g. '0'). Bare numeric coins are canonical; legacy '#0' / '%230' forms are also accepted.Returns price, size, side, and timestamps over a time range. Supports cursor pagination.",
    {
      coin: Hip4CoinParam,
      ...HistoryParams,
    },
    ListOutputSchema,
    async (params) => {
      const q = buildHistoryQuery(params.start, params.end, params.limit, params.cursor);
      const result = await hip4Request(`/trades/${normalizeHip4Coin(params.coin)}`, q);
      return formatCursorResponse(result);
    }
  );

• src/index.ts:1668-1672 (handler)

  The handler function that executes the tool logic. It builds query params via buildHistoryQuery, normalizes the HIP-4 coin, calls hip4Request to GET /v1/hyperliquid/hip4/trades/{coin}, and returns formatted cursor response.

  async (params) => {
    const q = buildHistoryQuery(params.start, params.end, params.limit, params.cursor);
    const result = await hip4Request(`/trades/${normalizeHip4Coin(params.coin)}`, q);
    return formatCursorResponse(result);
  }

• src/index.ts:63-67 (schema)

  Hip4CoinParam - the Zod schema for the coin input parameter used by get_hip4_trades, describing HIP-4 outcome-market coin symbols in bare numeric form.

  const Hip4CoinParam = z
    .string()
    .describe(
      "HIP-4 outcome-market coin symbol. Canonical form is the bare numeric '<10*outcome_id + side>' (e.g. '0' for outcome 0 Yes, '1' for outcome 0 No, '10' for outcome 1 Yes). The legacy '#0' and '%230' forms are also accepted. Use get_hip4_instruments to list all."
    );

• src/index.ts:1539-1559 (helper)

  buildHistoryQuery - helper function used by get_hip4_trades handler to construct query parameters (start, end, limit, cursor) from the tool's input params.

  function buildHistoryQuery(
    start?: number | string,
    end?: number | string,
    limit?: number,
    cursor?: string,
    extra?: Record<string, unknown>
  ): Record<string, unknown> {
    const range = resolveTimeRange(start, end);
    const q: Record<string, unknown> = {
      start: range.start,
      end: range.end,
      limit: resolveLimit(limit),
    };
    if (cursor) q.cursor = cursor;
    if (extra) {
      for (const [k, v] of Object.entries(extra)) {
        if (v !== undefined) q[k] = v;
      }
    }
    return q;
  }

• src/index.ts:1487-1537 (helper)

  hip4Request - the HTTP helper that makes REST API calls to the HIP-4 endpoint (https://api.0xarchive.io/v1/hyperliquid/hip4). Used by get_hip4_trades handler to GET /trades/{coin}.

  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);
    }
