Daily Market Summary

Generate a daily cryptocurrency market summary report with real-time data from public APIs.

Workflow

Step 1: Fetch Real-Time Data

Run the data collection script:

python scripts/fetch_data.py

This fetches from multiple public APIs (no authentication required):

• Binance: BTC/ETH tickers, all USDT pairs for ranking, funding rates
• Alternative.me: Fear & Greed Index
• CoinGecko: Trending coins
• mempool.space: BTC network fees

Output: market_data.json in the current working directory.

Step 2: Generate HTML Report

python scripts/generate_report.py market_data.json market_summary.html

Reads market_data.json and produces a styled HTML report.

Step 3: Present to User

• Use preview_url to show the HTML report in the browser.
• Use deliver_attachments to send the file to the user.
• Provide a concise text summary of key data points below the report.

Report Requirements

The report MUST include these sections:

1. BTC & ETH 24h 行情 — Price, 24h change %, high/low, volume, trades
2. 涨跌榜 — Top 3 gainers and top 3 losers (filtered by >$1M volume)
3. 市场情绪 — Fear & Greed Index with visual gauge + BTC/ETH funding rates
4. 热门趋势 & 链上动态 — CoinGecko trending + BTC mempool fees as network activity proxy

Data Presentation Rules

• ALL data must be queried in real-time — never use cached or hardcoded data
• Present data in table format with clear headers
• Always annotate the query timestamp (e.g., "查询时间：2026-04-18 17:30 UTC+8")
• Use Chinese stock market convention: RED = up (涨), GREEN = down (跌)
• NEVER include any trading advice, buy/sell recommendations, or price predictions
• If an API fails, note which data source is unavailable and continue with the rest

Script Notes

• scripts/fetch_data.py: Data collection from public APIs. No proxy needed — Binance public API is globally accessible. If Binance fails, try setting HTTPS_PROXY if a proxy is available.
• scripts/generate_report.py: HTML report generator. Takes JSON input and produces a dark-themed responsive HTML file.
