• server.py:1167-1181 (handler)

  The asynchronous handler function for the 'get_all_crypto_quotes' tool. It retrieves batch cryptocurrency quotes from the Financial Modeling Prep API using the FMP_API_KEY environment variable and returns the data as a JSON string.

  async def get_all_crypto_quotes() -> str:
      """批量获取加密货币行情"""
  
      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/batch-crypto-quotes"
      try:
          resp = requests.get(url, params={"apikey": api_key}, timeout=10)
          resp.raise_for_status()
          data = resp.json()
      except Exception as e:
          return f"Error: getting batch crypto quotes: {e}"
      return json.dumps(data)
