About the APIs

Grok API

• Only uses Grok API when XAI_API_KEY environment variable is set
• When not set, generates report from yfinance data only (for stock)

2-Layer Structure

1. Layer 1 (yfinance): Always available (fundamentals, price data)
2. Layer 2 (Grok API): When XAI_API_KEY is set (X posts, web search for deep analysis)

• industry / market / business require Layer 2. Displays a message when not set

API Status Summary (KIK-431)

Displays Grok API status at the end of each report:

Status	Display
Normal	✅ OK
Not set	🔑 Not set — Set XAI_API_KEY to enable
Auth error	❌ Auth error (401) — Check your XAI_API_KEY
Rate limit	⚠️ Rate limited (429) — Wait and retry
Timeout	⏱️ Timeout — Check network connection
Other error	❌ Error — Check stderr for details

Output Supplement

For stock

• Point out any divergence between value score and market sentiment
• Add additional context relevant to investment decisions

For industry

• Supplement Japan-specific circumstances (regulatory environment, entry barriers, etc.)
• Suggest related stock screening (/screen-stocks integration)

For market

• Estimate impact on portfolio (/stock-portfolio integration)
• Mention comparable past cases if available

For business

• Supplement fundamentals consistency using /stock-report results

Knowledge Integration Rules (KIK-466)

When get_context.py output contains the following, integrate with research results:

• Relation to held stocks: If the research target sector includes PF holdings, "7203.T is affected → health check recommended"
• Past research (SUPERSEDES): Compare with previous research on the same target. "2 weeks ago: neutral sentiment → now: slightly bullish"
• Investment notes: If there are concerns or thesis for the target stock, cross-check with research results and suggest updates
• Watchlist: If the research target is on the watchlist, add context: "Watching → material for buy timing decision"

Prompting to Record Analysis Conclusions

When a response for stock/business/industry research contains specific investment opinions or thesis-level conclusions:

💡 This analysis has not yet been recorded as an investment note. Would you like to record it as a thesis or concern?
