Alpaca has lifted its minimum deposit requirement from $30,000 to $1 for non-US users, allowing everyone to access their Trading API. To comply with regulatory requirements, the company is partnering with international KYC providers that verify identity through innovative methods such as uploading documents and taking a selfie. Once account approval is received, users can fund their accounts via wire transfer or bank transfer using one of Alpaca's payment providers. This change aims to bring investing power to everyone globally.
