About this API

Binance is a crypto exchange founded in 2017, the world's largest by volume since 2018. Its API is the de-facto standard in crypto trading — many algo trading bots, arbitrage tools, TradingView integrations use Binance API. Functional coverage: spot + futures (USD-M, COIN-M perpetuals) + options + margin + earn + Launchpad — all Binance services. REST API for orders and account ops; WebSocket for real-time market streams (per-tick, order book updates). Rate limits use "weight" mechanism (different endpoints have different weights, 1200 weight/min total) — finer than simple X/sec. Rich SDKs — Python has ccxt (unified multi-exchange abstraction) and python-binance dedicated lib.
