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:

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

Analyze market conditions:

./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

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

Output: data/crypto-latest.json

Fetch Stocks/Macro Only

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

Output: data/stocks-latest.json

Fetch Everything

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

Automated Analysis

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

./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:

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

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

#!/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

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}%")
