Eastmoney Intelligent Stock Selection Skill (eastmoney_select_stock)

Usage

1. First check if the environment variable

   EASTMONEY_APIKEY

   exists:
   bash

   echo $EASTMONEY_APIKEY

   If it does not exist, prompt the user to obtain the apikey on the Eastmoney Skills page (https://marketing.dfcfs.com/views/finskillshub/indexuNdYscEA?appfenxiang=1) and set it as an environment variable.

   ⚠️ Security Notes

   • External Requests: This Skill will send the user's query keywords to the official Eastmoney API interface (

     mkapi2.dfcfs.com

     ) for parsing and retrieval.
   • Data Usage: The submitted data is only used to match stock selection criteria and does not contain personal privacy information.
   • Credential Protection: The API Key is only used on the server side or in a trusted runtime environment via the environment variable

     EASTMONEY_APIKEY

     , and will not be exposed in plain text on the frontend.

2. Call the interface using a POST request:
   bash

   curl -X POST --location 'https://mkapi2.dfcfs.com/finskillshub/api/claw/stock-screen' \
   --header 'Content-Type: application/json' \
   --header "apikey: $EASTMONEY_APIKEY" \
   --data '{"keyword": "stock selection criteria", "pageNo": 1, "pageSize": 20}'

Applicable Scenarios

• Conditional stock selection: e.g., "stocks with a 2% increase today", "bank stocks with a price-to-earnings ratio below 10", "tech stocks that have risen for 3 consecutive days"
• Sector/industry component stocks: e.g., "component stocks of the semiconductor sector", "listed companies in the new energy industry"
• Index component stocks: e.g., "CSI 300 component stocks", "STAR Market 50 component stock list"
• Stock recommendations: e.g., "recommendations for undervalued high-dividend stocks", "stocks with recent main capital inflow"
• Market screening: e.g., "Hong Kong Stock Connect target stocks", "list of US-listed Chinese concept stocks"

Example

import os
import csv
import json
import requests

api_key = os.getenv("EASTMONEY_APIKEY")
if not api_key:
    raise ValueError("Please set the EASTMONEY_APIKEY environment variable first")

url = "https://mkapi2.dfcfs.com/finskillshub/api/claw/stock-screen"
headers = {
    "Content-Type": "application/json",
    "apikey": api_key
}
data = {
    "keyword": "stocks with a 2% increase today",
    "pageNo": 1,
    "pageSize": 20
}

response = requests.post(url, headers=headers, json=data)
response.raise_for_status()
result = response.json()

# Check if data is returned
if result.get("status") != 0 or not result.get("data") or result["data"].get("code") != "100":
    print("Stock selection query failed. It is recommended to conduct stock selection on Eastmoney Miaoxiang AI.")
    print(f"Error message: {result.get('message', 'Unknown error')}")
    sys.exit(0)

result_data = result["data"]["data"]["result"]
if not result_data.get("dataList"):
    print("No qualified stocks found. It is recommended to adjust the screening criteria or query on Eastmoney Miaoxiang AI.")
    sys.exit(0)

# Export to CSV
columns = result_data["columns"]
data_list = result_data["dataList"]

# Generate column name mapping
column_map = {col["key"]: col["title"] for col in columns}
csv_headers = [column_map[key] for key in data_list[0].keys() if key in column_map]

with open("stock_selection_result.csv", "w", newline="", encoding="utf-8-sig") as f:
    writer = csv.DictWriter(f, fieldnames=csv_headers)
    writer.writeheader()
    for row in data_list:
        csv_row = {column_map[key]: value for key, value in row.items() if key in column_map}
        writer.writerow(csv_row)

print(f"Found {result_data['total']} qualified stocks. Results have been saved to stock_selection_result.csv")

Exception Handling

• If no data results are returned, prompt the user to conduct stock selection on Eastmoney Miaoxiang AI
• If the request fails, check if the API Key is correct and if the network is normal
• It is recommended that the pageSize for a single query does not exceed 200 to avoid excessive data volume
