Alpaca has launched its public beta for its crypto trading API, offering a developer-friendly interface for accessing real-time data and executing trades with low costs. The partnership with ErisX enables fast execution, reliable technology infrastructure, and superior custody of digital assets. The API supports multiple programming languages and offers paper trading and live trading options, as well as 24/7 global support. Developers can build their own crypto apps using the Alpaca Broker API suite, which will also enable both crypto and stock trading. Cryptocurrency trading involves high risks and is not regulated in most countries, so users should have appropriate knowledge and experience before engaging in it.
