• server.py:1261-1279 (handler)

  The handler function that executes the tool logic: fetches latest crypto news from Financial Modeling Prep API using page and limit parameters, returns JSON string or error message.

  async def get_crypto_latest_news(page: int = 0, limit: int = 20) -> str:
      """获取最新加密货币新闻"""
  
      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/news/crypto-latest"
      try:
          resp = requests.get(
              url,
              params={"page": page, "limit": limit, "apikey": api_key},
              timeout=10,
          )
          resp.raise_for_status()
          data = resp.json()
      except Exception as e:
          return f"Error: getting latest crypto news: {e}"
      return json.dumps(data)
