  description: >-
    The Coinbase Prime API enables institutions to manage cryptocurrency
    trading and custody on behalf of their clients. It supports programmatic
    trading strategies, automated platform processes, portfolio management,
    and custodial operations. The REST API provides endpoints for order
    execution, account management, transaction history, and reporting,
    designed for institutional-grade workflows and compliance requirements.
    API keys are scoped to individual portfolios and require HMAC SHA-256
    authentication.
