Implementation Reference

• server.py:1146-1160 (handler)

  The handler function that implements the tool logic: fetches short crypto quote for a given symbol using the Financial Modeling Prep API, returns JSON string or error message.

  async def get_crypto_quote_short(symbol: str) -> str:
      """获取加密货币简短报价"""
  
      api_key = os.environ.get("FMP_API_KEY")
      if not api_key:
          return "Error: FMP_API_KEY environment variable not set."
  
      url = "https://financialmodelingprep.com/stable/quote-short"
      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 short crypto quote for {symbol}: {e}"
      return json.dumps(data)
