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:

CODEBLOCK0

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

Workflow

1. 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:

• - INLINECODE9
• INLINECODE10
• INLINECODE11
• INLINECODE12
• INLINECODE13

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.
