## 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
