About Binance

This repository contains the official documentation for Binance's Spot trading APIs and streams, covering REST API, WebSocket API, FIX API, and market data streams (including Simple Binary Encoding). It documents endpoints, parameters, payloads, enums, error codes, and filters for Spot trading, alongside coverage of related Binance services such as Margin Trading, Derivatives (UM/CM Futures, Options, Portfolio Margin), Wallet, Sub-Account, Simple Earn, Staking, Convert, Pay, and NFT APIs.

The repository is aimed at developers building applications or trading systems that integrate with Binance, providing reference material for connecting via REST, WebSocket, or FIX protocols. It includes links to official connector libraries in Python, Node.js, Ruby, .NET, C#, Java, Rust, PHP, Go, and TypeScript, as well as Postman collections and a Swagger/OpenAPI specification.

Additional resources include a Spot Testnet for practicing trading without real funds (API-only, limited to /api endpoints), FAQ documents explaining API behaviors such as commission calculations, self-trade prevention, market orders, and smart order routing, and a changelog tracking updates to the APIs.
