# Python APIs

> Which GRID SDK solves which job

One platform, one reference per API surface. Start from the job, not the package name:

| You want to…                                                    | Use                    | Start at                                                           |
| --------------------------------------------------------------- | ---------------------- | ------------------------------------------------------------------ |
| Call hosted models (depth, detection, grasping, VLMs, VLAs)     | **grid-cortex-client** | [`CortexClient`](/v2.0/python-api/grid-cortex-client/cortexclient) |
| Connect to a robot and dispatch commands                        | **grid-nexus-client**  | [`connect`](/v2.0/python-api/grid-nexus-client/connect)            |
| Look up what a robot can actually do (`standUp`, `getImage`, …) | **Robot interface**    | [`Robot`](/v2.0/python-api/robot-interface/robot)                  |
| Drive a robot in the AirGen (Unreal) simulator                  | **AirGen robots**      | [`AirGenDrone`](/v2.0/python-api/airgen-robots/airgendrone)        |
| Drive a robot in the Isaac Sim simulator                        | **Isaac robots**       | [`IsaacArm`](/v2.0/python-api/isaac-robots/isaacarm)               |
| Move objects and reset the scene in Isaac Sim                   | **Isaac scene**        | [`IsaacClient`](/v2.0/python-api/isaac-scene/isaacclient)          |
| Pass poses, velocities, images between all of the above         | **grid-types**         | [`overview`](/v2.0/python-api/grid-types/overview)                 |

Every page in this section is generated from the package source — signatures,
parameters, and examples are the code's own docstrings, verified fresh in CI.
