Alpaca

Alpaca Broker API provides trading and market data. Accounts hold positions; activities log trades; assets/calendar/clock are reference data.

Data Model

  • Accounts are brokerage accounts. Documents (statements, etc.) are account-scoped — need acc_id.
  • Activities are account events (trades, transfers). Assets are tradable securities.
  • Calendar returns market days. Clock returns market open/close status.
  • Country info supports compliance. Documents require account id.

Gotchas

  • Paper vs live: API base URL differs (paper-api vs api). Credentials are separate per environment.
  • acc_id required: Account-scoped tools (documents, activities) need account id from listing accounts.
  • Market hours: Use clock to check if market is open before trading operations.
