Types and exceptions

Use this section after choosing an operation or workflow. It documents the objects that cross those interfaces without repeating the methods themselves.

Category	Use it to understand
Client and configuration	How to construct the sync or async client and permit live mutations.
Requests and responses	Where request validation and typed results belong.
Streaming	How subscriptions are declared and updates are delivered.
Exceptions	What failures mean and whether an operation is safe to retry.

The supported convenience imports are exported from ig_trading_lib. Operation-specific request and response types remain in their resource modules and are linked from the method that consumes or returns them.

The checked public-api.yml contract and public-api-index.json remain the machine-readable sources for tooling. They are not a second human-facing method hierarchy.
