# API reference

Use the API reference when you need exact Python method names, parameters,
return values, and examples for integrating AODT into your own scripts or
applications.

## Available References

* [DigitalTwinClient API](/api/client): connect to the Digital Twin server, load scenarios, inspect status, run full simulations, request CIRs, fetch NumPy results, and manage client sessions.
* [Config Builder API](/api/config): build simulation YAML in Python using `SimConfig`, panels, DUs, RUs, UEs, S3 settings, Parquet export settings, and calibration-related configuration.
* [EM Solver API](/api/em-solver): reference for EM Solver interfaces.

## Where To Start

* If you are running simulations, start with [DigitalTwinClient](/api/client).
* If you are creating the scenario YAML passed to `client.start(...)`, start with [Config Builder](/api/config).
* If you need low-level EM Solver reference, start with [EM Solver API](/api/em-solver).
* For workflow guidance before diving into signatures, see [AODT Client](/aodt-client).
