When to use

Trigger phrases:

• CPI / core CPI / PCE / PPI / inflation / 通胀 / 核心通胀
• GDP / 国内生产总值
• unemployment / 失业率 / U-3 / U-6 / nonfarm / 非农
• Fed funds / 联储利率 / SOFR
• 2Y / 10Y yield / yield curve / 美债利率 / 收益率曲线

Workflow

1. Resolve user phrasing to a FRED series ID — first via aliases.json (curated), then search.py if no alias matches.
2. Run series.py <SERIES_ID|alias> for observations + metadata.
3. Synthesise NL reply with units, frequency, and last update date; cite "Source: St. Louis Fed (FRED)".

Environment is auto-loaded on script import from .env at project root (or ~/.config/market-intel/env as fallback) — no manual source needed.

Error handling

Exit code	Meaning	LLM action
0	Success	Parse data, narrate.
2	Missing FRED_API_KEY	Tell user to register at https://fred.stlouisfed.org/docs/api/api_key.html and add to .env at project root.

Known limitations

• Daily series may have weekend/holiday gaps (FRED returns NaN as .; we normalise to null).
• "Discontinued" series filtered by default in search.py — use --include-discontinued to override.
• Series metadata cache TTL 24 h; observation cache TTL 1 h. Use --fresh for the latest.
