Implementation notes

When to use Binance Public API

Binance's public API endpoints give free access to real-time order book data, recent trades, and 24-hour ticker statistics for all listed pairs — without authentication. At 1,200 requests/minute (plus separate WebSocket limits), it is the highest-throughput free crypto data source available.

Common pitfalls

Binance uses a weight-based rate limiting system. Each endpoint has a `weight` value (1-50), and the limit is 1,200 total weight per minute, not 1,200 individual requests. The order book endpoint with `limit=5000` has a weight of 250 — five calls exhaust your minute budget. Always check the `X-MBX-USED-WEIGHT-1M` response header.
The public endpoints (`api.binance.com`) are geo-blocked in several countries. Users in the US, Canada, UK, and others may need to use `api.binance.us` (Binance.US), which has a different set of listed pairs and a separate rate limit policy.
Binance uses microsecond timestamps in its response data (13-digit Unix timestamps in milliseconds, not seconds). Treating these as second-epoch timestamps — a common mistake — returns dates in 2554. Always divide by 1,000 or use a millisecond-aware parser.
Symbol names use no delimiter between base and quote asset: `BTCUSDT`, not `BTC/USDT` or `BTC-USDT`. The `/api/v3/exchangeInfo` endpoint lists all valid symbols and their precision rules before you make any trade-related calls.

Quick start (bash)

curl "https://api.binance.com/api/v3/ticker/24hr?symbol=BTCUSDT" | python3 -m json.tool | grep -E '"symbol"|"lastPrice"|"priceChangePercent"'
