Crypto Market Analyzer

Fetch real-time crypto prices and calculate technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands, ATR) for BTC, ETH, SOL, BNB, XRP, DOGE. Powered by multi-source data (Binance, CoinGecko, CoinCap, CryptoCompare).

This skill provides two core capabilities for cryptocurrency analysis:

1. Real-time Market Data — Get current prices, 24h changes, volume, and highs/lows
2. Technical Indicator Analysis — Calculate professional-grade indicators with trading signals

Supported Coins

BTC, ETH, SOL, BNB, XRP, DOGE

Dependencies

The scripts require the requests Python library. Install it if not available:

bash

pip install requests

Billing

This is a paid skill. Each invocation costs 0.001 USDT, charged via SkillPay. Pass the --user flag with the user's ID for billing. If the user's balance is low, the script will return a payment_url — present this link to the user.

Interpreting the Output

When presenting results to the user, focus on these key elements:

For Market Data:

• Price and 24h change are the most important
• Mention volume for context on market activity
• Flag if change_24h is extreme (> ±5%)

For Technical Analysis:

• overall_assessment gives the summary: STRONG BUY / BUY / NEUTRAL / SELL / STRONG SELL
• signal_score ranges from -100 (extremely bearish) to +100 (extremely bullish)
• signals array lists the specific reasons behind the assessment
• RSI: <30 = oversold (buy opportunity), >70 = overbought (sell opportunity)
• MACD histogram > 0 = bullish momentum, < 0 = bearish momentum
• Bollinger Band position: <0.1 = near support, >0.9 = near resistance

Important Disclaimer:

Always remind users that technical indicators are for educational/analysis purposes only and do not constitute financial advice. Cryptocurrency markets are highly volatile.

Error Handling

If a script returns an error, check:

1. Payment error — Present the payment_url to the user to top up balance
2. Data source error — All APIs failed; suggest trying again in a few minutes
3. Invalid coin — List the supported coins: BTC, ETH, SOL, BNB, XRP, DOGE
