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

APIRate LimitNotes
CoinGecko10-50 calls/minFree tier, no key required
Alternative.meUnlimitedPublic endpoint
DeFi LlamaUnlimitedPublic endpoint
Yahoo Finance~2000 calls/hourUnofficial 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

#!/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}%")
