Implementation Reference

• server.py:1215-1233 (handler)

  The handler function that implements the get_crypto_intraday tool by fetching intraday crypto price data from the Financial Modeling Prep API, validating the interval, and returning JSON data.

  async def get_crypto_intraday(symbol: str, interval: str = "1min") -> str:
      """获取加密货币的分时价格"""
  
      api_key = os.environ.get("FMP_API_KEY")
      if not api_key:
          return "Error: FMP_API_KEY environment variable not set."
  
      allowed = {"1min", "5min", "1hour"}
      if interval not in allowed:
          return "Error: invalid interval"
  
      url = f"https://financialmodelingprep.com/stable/historical-chart/{interval}"
      try:
          resp = requests.get(url, params={"symbol": symbol, "apikey": api_key}, timeout=10)
          resp.raise_for_status()
          data = resp.json()
      except Exception as e:
          return f"Error: getting {interval} crypto data for {symbol}: {e}"
      return json.dumps(data)
