  title: State Street Alpha Data Platform Baskets Funds API
  description: The State Street Alpha Data Platform API provides institutional investment managers, asset owners, and wealth managers with programmatic access to their portfolio data across the front-to-back Alpha investment management platform. The API enables clients to retrieve portfolio positions, holdings, investable cash, pledged collateral, securities on loan, risk exposures, performance measurement, and transaction history in near real-time. Built on Snowflake and Microsoft Azure, the Alpha Data Platform provides intraday visibility across geographies, asset classes, and counterparties. Authentication uses OAuth 2.0 Client Credentials (RFC 6749 Section 4.4.2). All requests require the X-Correlation-ID header for request tracing. The API follows REST conventions with JSON as the default data format, versioned using Major.Minor.Patch semantics.
