This repository contains the official documentation for Binance Spot trading APIs. It is not a software application or data research project; it is a comprehensive reference for developers building trading clients. The documentation covers REST API, WebSocket API, WebSocket Streams, FIX API, and Simple Binary Encoding (SBE) protocols. It includes detailed specifications for endpoints, message formats, authentication, rate limits, error codes, and trading rules. The repository also provides versioned SBE XML schemas, FIX QuickFIX schemas, changelogs, and frequently asked questions. The documentation is bilingual (English and Chinese) and is actively maintained with frequent updates to reflect API changes. While the repository contains no executable code, the schema files and reference documents are essential for implementing Binance Spot integration.
