Cross-Exchange Comparison

For price comparison across exchanges, fetch tickers from multiple exchanges in parallel and present in a table. Example approach:

1. Fetch BTC price from all 6 exchanges simultaneously
2. Compare bid/ask spreads
3. Note volume differences
4. Flag significant price discrepancies (potential arbitrage)

Usage Tips

• Public endpoints need no authentication — use for prices, order books, volume
• For private endpoints (trading, balances), see references/cex-auth.md
• Always use the correct symbol format per exchange (see table above)
• Binance has the highest volume for most pairs — use as price reference
• Funding rates indicate market sentiment: positive = longs pay shorts (bullish bias)
• Rate limits vary: Binance ~1200/min, Coinbase ~10/sec, Kraken ~1/sec
• For kline intervals: 1d or 1D or 1440 depending on exchange
