This repository is the official documentation for the Binance Spot Exchange APIs. It provides comprehensive specifications for REST, WebSocket, FIX, and SBE (Simple Binary Encoding) protocols, covering trading, market data, account management, and user data streams. The documentation includes detailed endpoint references, authentication methods (HMAC, RSA, Ed25519), order types, filters, error codes, and FAQs. It also contains versioned SBE XML schemas for code generation and lifecycle management JSON files. While not an application itself, it serves as the authoritative reference for developers building trading bots, market-making systems, and integration tools for Binance Spot. The repository is well-structured with bilingual (English/Chinese) support and separate documentation for production, testnet, and demo environments.
