How can you get real-time Bitcoin market data?

Here's how real-time Bitcoin market data actually gets collected, in the order of where it comes from:

1. The source is the exchanges themselves. Every price starts as an order on a specific trading venue (Binance, Coinbase, Kraken, etc.). There's no single "official Bitcoin price" — what you see is an aggregate of what's being paid on each exchange right now.

2. Public API feeds. Exchanges expose public REST endpoints and WebSocket streams that anyone can query without an account. WebSocket is the true "real-time" layer — it pushes price/trade/ticker updates to you the moment they happen, rather than you polling every few seconds.

3. Aggregators (what most apps actually use). Services like CoinGecko pull and average prices across many exchanges, so the figure you see isn't one venue's price but a market-wide composite. The trade-off: aggregators update on an interval (often every 1–5 minutes), so they're "near real-time" rather than tick-by-tick.

4. On-chain data adds a different angle. For DeFi, real-time data also comes from reading the blockchain directly — pool reserves, swap events, and liquidity on DEXs (via services like DexScreener). That's the on-chain market, separate from the centralized order books.

5. What "real-time" actually means to you: for a chart/portfolio app, ~1-minute aggregated data is plenty; for scalping, you'd want the raw WebSocket feed from one specific exchange, because the latency difference matters at that scale.

That's the general picture — but if you want the actual number right now, I can pull Bitcoin's live price, market cap, 24h volume, and 24h change for you directly. Want me to grab it?
