Binance Spot WebSocket Streams

Binance Spot WebSocket Streams deliver real-time market data updates via persistent WebSocket connections. Developers can subscribe to individual symbol ticker streams, aggregate trade streams, kline and candlestick data, depth-of-book updates, and mini-ticker streams. The service supports both single and combined stream subscriptions, enabling efficient consumption of live market data for trading bots, dashboards, and analytics applications without polling the REST API.

Where this information came from

This is an independent, third-party profile of Binance Spot WebSocket Streams, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
