  "signal_level": "MEDIUM",
  "market_note": "市场偏恐慌，情绪面有支撑，注意底部信号。",
  "history": [...],
  "data_source": "alternative.me"
}

Contrarian signal logic:

• Extreme Fear (≤20) → 🔴 HIGH (historical buy opportunity)
• Fear (21-40) → 🟡 MEDIUM
• Neutral (41-60) → 🟢 LOW
• Greed (61-79) → 🟢 LOW
• Extreme Greed (≥80) → 🔴 HIGH (caution, potential top)

Signal Levels

Note: crypto-kol-signals signal_level is based on dominance_change (independent of the sentiment+surge rule above). Extreme dominance change (>50% or \x3C-50%) → HIGH; moderate change → MEDIUM; otherwise LOW.

Workflow

Check Market Sentiment (most common)

1. crypto-fear-greed { days: 7 }           ← overall market mood
2. crypto-social-trending { limit: 10 }    ← what's hot
3. Present combined view to user

Analyze Specific Token

1. crypto-sentiment-score { symbol: "ETH" }
2. crypto-kol-signals { symbol: "ETH", threshold: 1.5 }
3. Combine: sentiment score + dominance signal → final assessment

Early Warning Scan

1. crypto-mention-surge { threshold: 2.0, limit: 10 }
2. For tokens with HIGH/MEDIUM signals → crypto-sentiment-score to confirm
3. Alert user to tokens with multiple converging signals

Combined with Smart Money

When social signal + on-chain signal converge:

1. crypto-mention-surge detects abnormal spike
2. → Call smart-money-signal to check if whales are buying
3. Two signals converging → stronger conviction
