Data & APIs

Resolve a China A-share stock name or code in pure Node.js, fetch daily historical bars from Eastmoney HTTP APIs, and archive them as local JSON files. Use when the request is about 日线, 历史K线, daily history, candles, OHLCV, raw market data export, or stock-name-or-code to API to JSON persistence for inputs such as 600519, 300750.SZ, or 贵州茅台.

Fetch Stock Daily JSON

Use this skill for the publishable Node.js path stock input -> symbol resolution -> daily history fetch -> raw JSON archive.

Quick Start

Run the Node.js helper from the repo root:

node skills/fetch-stock-daily-json/scripts/fetch_daily_json.js 贵州茅台
node skills/fetch-stock-daily-json/scripts/fetch_daily_json.js 600519 --years 3
node skills/fetch-stock-daily-json/scripts/fetch_daily_json.js 宁德时代 --start-date 20240101 --end-date 20260329 --adjust qfq

The script prints a JSON summary with the resolved symbol, row count, requested window, actual trade-date bounds, and saved file path.

Workflow

  1. Accept repo-compatible inputs only: 6-digit code, 600519.SH or 300750.SZ, or a Chinese stock name. Do not use sh600519.
  2. Prefer the bundled Node.js script instead of re-implementing the workflow in the task.
  3. Resolve stock names through the Eastmoney A-share list API and cache the code-name map locally.
  4. Fetch daily bars from the Eastmoney historical kline API with daily period and qfq/hfq/none adjustment.
  5. Save the archived rows under data/raw/eastmoney/daily_history/YYYYMMDD/<symbol>_<HHMMSS>.json.
  6. Default to years=5 and adjust=qfq when the user does not provide a date window.
  7. Stop after JSON archive generation unless the user explicitly asks for downstream parsing, analysis, or DB sync.

Return Format

Return the script's JSON summary and call out:

  • resolved_symbol
  • rows
  • trade_date_min
  • trade_date_max
  • output_path

Failure Handling

  • If name resolution fails, ask for a valid 6-digit A-share code or Chinese stock name.
  • If the fetch returns zero rows, keep the archive file and report rows: 0.
  • If you need the JS-side API details or the parity notes versus the Python workflow, read references/lobsterclaw-workflow.md.
