快速入门

import * as crypto from "crypto";

const API_BASE = "https://api.elections.kalshi.com/trade-api/v2";

// See AUTHENTICATION.md for full setup
function getAuthHeaders(
  apiKey: string,
  privateKeyPem: string,
  method: string,
  path: string
): Record<string, string> {
  const timestamp = Date.now().toString();
  const message = `${timestamp}${method}${path}`;

  const sign = crypto.createSign("RSA-SHA256");
  sign.update(message);
  const signature = sign.sign(privateKeyPem, "base64");

  return {
    "KALSHI-ACCESS-KEY": apiKey,
    "KALSHI-ACCESS-SIGNATURE": signature,
    "KALSHI-ACCESS-TIMESTAMP": timestamp,
    "Content-Type": "application/json",
  };
}

常见操作

搜索市场
async function searchMarkets(query: string, limit = 10): Promise<Market[]> {
  const url = new URL(`${API_BASE}/markets`);
  url.searchParams.set("status", "open");
  url.searchParams.set("limit", String(limit));

  const response = await fetch(url.toString());
  const data = await response.json();

  // Filter by query in title
  return data.markets.filter((m: Market) =>
    m.title.toLowerCase().includes(query.toLowerCase())
  );
}
获取市场详情
async function getMarket(ticker: string): Promise<Market> {
  const response = await fetch(`${API_BASE}/markets/${ticker}`);
  const data = await response.json();
  return data.market;
}
获取订单簿
async function getOrderbook(ticker: string): Promise<Orderbook> {
  const response = await fetch(`${API_BASE}/markets/${ticker}/orderbook`);
  const data = await response.json();
  return data.orderbook;
}
查询余额（需认证）
async function getBalance(
  apiKey: string,
  privateKeyPem: string
): Promise<Balance> {
  const path = "/portfolio/balance";
  const headers = getAuthHeaders(apiKey, privateKeyPem, "GET", path);

  const response = await fetch(`${API_BASE}${path}`, { headers });
  return response.json();
}
获取持仓（需认证）
async function getPositions(
  apiKey: string,
  privateKeyPem: string
): Promise<Position[]> {
  const path = "/portfolio/positions";
  const headers = getAuthHeaders(apiKey, privateKeyPem, "GET", path);

  const response = await fetch(`${API_BASE}${path}`, { headers });
  const data = await response.json();
  return data.market_positions;
}
下单（需认证）
async function placeOrder(
  apiKey: string,
  privateKeyPem: string,
  ticker: string,
  side: "yes" | "no",
  action: "buy" | "sell",
  count: number,
  price: number // In cents (1-99)
): Promise<Order> {
  const path = "/portfolio/orders";
  const headers = getAuthHeaders(apiKey, privateKeyPem, "POST", path);

  const body = {
    ticker,
    side,
    action,
    count,
    type: "limit",
    ...(side === "yes" ? { yes_price: price } : { no_price: price }),
  };

  const response = await fetch(`${API_BASE}${path}`, {
    method: "POST",
    headers,
    body: JSON.stringify(body),
  });
  const data = await response.json();
  return data.order;
}

核心概念

  • 市场：包含 Yes/No 结果的事件合约（例如，“X 会在 Y 日期前发生吗？”）
  • 价格：以美分报价（1–99），代表概率百分比
  • 持仓：你持有的 Yes 或 No 合约
  • 结算：市场结算为 $1.00（Yes 获胜）或 $0.00（No 获胜）

提示

  1. 从市场调研开始：使用 searchMarkets() 探索机会
  2. 检查流动性：下大额订单前查看订单簿深度
  3. 使用限价单：避免使用市价单，以控制成交价格
  4. 监控持仓：定期检查持仓和盈亏
