# Crypto Market Intelligence

Real-time market data pipeline for crypto, stocks, and macro indicators. Zero API keys required. All data fetched from free public APIs.

## When to Use

Trigger this skill when you need:
- Current cryptocurrency prices and market caps
- Bitcoin/Ethereum dominance
- Fear & Greed Index
- Trending coins
- DeFi Total Value Locked (TVL)
- Stock market indices (S&P 500, Nasdaq, Dow, VIX)
- AI stock prices (NVDA, AMD, MSFT, etc.)
- Macro indicators (DXY dollar index, 10Y Treasury yield)
- Pre-fetched data for trading analysis
- Market intelligence for portfolio decisions

## Quick Start

Fetch all market data:

```bash
cd ~/.openclaw/skills/crypto-market-intel/scripts
python3 market-data-fetcher.py all --output ~/market-data
```

Analyze market conditions:

```bash
./analyze-market.sh
```

## Core Features

✅ **6 Free APIs, Zero Keys**
- CoinGecko (coins, global metrics, trending)
- Alternative.me (Fear & Greed Index)
- DeFi Llama (DeFi TVL)
- Yahoo Finance (stocks, indices, bonds)

✅ **Crypto Coverage**
- Top 30 coins by market cap
- Global market metrics (total mcap, volume, dominance)
- Fear & Greed Index (current + 7-day history)
- Trending coins
- DeFi Total Value Locked

✅ **Stocks & Macro**
- Major indices (S&P 500, Nasdaq, Dow, VIX)
- AI stocks (NVDA, AMD, AVGO, MRVL, TSM, ASML, ARM, MSFT, AMZN, GOOG, META, ORCL)
- AI energy (VST, CEG, OKLO, SMR, TLN)
- AI infrastructure (VRT, ANET, CRDO)
- Dollar Index (DXY)
- 10-Year Treasury Yield

✅ **Agent-Ready Output**
- JSON format for easy parsing
- Structured data with timestamps
- Works as cron job or on-demand
- No hallucinated prices — real market data

## Usage

### Fetch Crypto Data Only

```bash
python3 scripts/market-data-fetcher.py crypto --output ./data
```

Output: `data/crypto-latest.json`

### Fetch Stocks/Macro Only

```bash
python3 scripts/market-data-fetcher.py stocks --output ./data
```

Output: `data/stocks-latest.json`

### Fetch Everything

```bash
python3 scripts/market-data-fetcher.py all --output ./data
```

### Automated Analysis

Run the analyzer wrapper to fetch data and generate a market summary prompt:

```bash
./scripts/analyze-market.sh ~/market-data
```

This fetches fresh data and outputs a structured prompt for the agent to analyze:
- Market sentiment (Fear & Greed)
- Top movers (biggest gains/losses)
- Macro environment (DXY, yields, VIX)
- Notable signals

## Cron Integration

Schedule hourly market data fetches:

```bash
crontab -e

# Fetch market data every hour
0 * * * * cd ~/.openclaw/skills/crypto-market-intel/scripts && python3 market-data-fetcher.py all --output ~/market-data
```

The agent can then read pre-fetched data for instant analysis without waiting for API calls.

## Rate Limits & Fair Use

| API | Rate Limit | Notes |
|-----|------------|-------|
| CoinGecko | 10-50 calls/min | Free tier, no key required |
| Alternative.me | Unlimited | Public endpoint |
| DeFi Llama | Unlimited | Public endpoint |
| Yahoo Finance | ~2000 calls/hour | Unofficial API, use responsibly |

**Recommendation:** Run fetcher hourly, not more frequently. APIs are free but fair use matters.

## Troubleshooting

**Problem:** Fetch fails with timeout

**Solution:** Check network connection, try again in a few minutes. Some APIs have temporary outages.

---

**Problem:** Yahoo Finance returns no data for a stock

**Solution:** Symbol may be delisted or unavailable. Check symbol accuracy (use `^` prefix for indices, e.g., `^GSPC`).

---

**Problem:** DeFi TVL is null

**Solution:** DeFi Llama API may be updating. Historical data endpoint occasionally has lag. Try again later.

---

**Problem:** Fear & Greed returns empty

**Solution:** Alternative.me may be down. Check https://alternative.me/crypto/fear-and-greed-index/ directly.

## Architecture Notes

- **No authentication** — all APIs are public, no keys to manage
- **HTTP requests only** — uses Python's built-in `urllib` (no external deps)
- **Error tolerant** — if one API fails, others still succeed
- **Portable** — works on any system with Python 3.7+
- **Configurable output** — use `--output` flag to set data directory

## Integration Examples

### Discord Bot Alert

```bash
#!/bin/bash
python3 scripts/market-data-fetcher.py crypto --output /tmp
FEAR=$(jq '.fear_greed[0].value' /tmp/crypto-latest.json)
if [ "$FEAR" -lt 25 ]; then
  echo "🚨 Extreme Fear detected: $FEAR — potential buy opportunity"
fi
```

### Trading Bot Pre-Analysis

```python
import json

# Load pre-fetched data
with open("~/market-data/crypto-latest.json") as f:
    data = json.load(f)

# Extract top movers
top_coins = data["top_coins"]
gainers = sorted(top_coins, key=lambda x: x["change_24h_pct"], reverse=True)[:5]

print("Top 5 Gainers (24h):")
for coin in gainers:
    print(f"{coin['symbol']}: +{coin['change_24h_pct']:.2f}%")
```
