# Viam's Client APIs Every Viam resource exposes an [application programming interface (API)](https://en.wikipedia.org/wiki/API) described through [protocol buffers](https://developers.google.com/protocol-buffers). The API methods provided by the SDKs for each of these resource APIs wrap gRPC client requests to the machine when you execute your program, providing you a convenient interface for accessing information about and controlling the resources you have [configured](https://docs.viam.com/hardware/configure-hardware/) on your machine. ## Platform APIs - [Fleet Management API](https://docs.viam.com/reference/apis/fleet/) Create and manage organizations, locations, and machines, get logs from individual machines, and manage fragments and permissions. - [Data Client API](https://docs.viam.com/reference/apis/data-client/) Upload, download, filter, tag or perform other tasks on data like images or sensor readings. - [Machine Management API](https://docs.viam.com/reference/apis/robot/) Manage your machines: connect to your machine, retrieve status information, and send commands remotely. - [ML Training Client API](https://docs.viam.com/reference/apis/ml-training-client/) Submit and manage ML training jobs running on Viam. - [Billing Client API](https://docs.viam.com/reference/apis/billing-client/) Retrieve billing information from Viam. - [Session Management API](https://docs.viam.com/reference/apis/sessions/) Manage sessions, heartbeats, and safety timeouts for connected clients. ## Component APIs These APIs provide interfaces for controlling and getting information from the components of a machine: -

[Camera API](https://docs.viam.com/reference/apis/components/camera/) Give commands for getting images or point clouds. - [Encoder API](https://docs.viam.com/reference/apis/components/encoder/) Give commands for getting the position of a motor or a joint in ticks or degrees. - [Gantry API](https://docs.viam.com/reference/apis/components/gantry/) Give commands for coordinated control of one or more linear actuators. - [Generic API](https://docs.viam.com/reference/apis/components/generic/) Give commands for running custom model-specific commands using DoCommand on your generic components. - [Gripper API](https://docs.viam.com/reference/apis/components/gripper/) Give commands for opening and closing a gripper device. - [Input controller API](https://docs.viam.com/reference/apis/components/input-controller/) Give commands to register callbacks for events, allowing you to use input devices to control your machines. - [Motor API](https://docs.viam.com/reference/apis/components/motor/) Give commands to operate a motor or get its current status. - [Movement sensor API](https://docs.viam.com/reference/apis/components/movement-sensor/) Give commands for getting the current GPS location, linear velocity and acceleration, angular velocity and acceleration and heading. - [Power sensor API](https://docs.viam.com/reference/apis/components/power-sensor/) Commands for getting measurements of voltage, current, and power consumption. - [Sensor API](https://docs.viam.com/reference/apis/components/sensor/) Give commands for getting sensor readings. - [Servo API](https://docs.viam.com/reference/apis/components/servo/) Give commands for controlling the angular position of a servo precisely or getting its current status. - [Switch API](https://docs.viam.com/reference/apis/components/switch/) Give commands for getting the state of a physical switch that has two or more discrete positions. ## Service APIs These APIs provide interfaces for controlling and getting information from the services you configured on a machine. - [Service APIs overview](https://docs.viam.com/reference/apis/services/overview/) See every service API and its methods at a glance in one compact grid. - [Data management service API](https://docs.viam.com/reference/apis/services/data/) Give commands to your data management service to sync data stored on the machine it is deployed on to the cloud. - [Vision service API](https://docs.viam.com/reference/apis/services/vision/) Give commands to get detections, classifications, or point cloud objects, depending on the ML model the vision service is using. - [ML model service API](https://docs.viam.com/reference/apis/services/ml/) Give commands to your ML model service to make inferences based on a provided ML model. - [Motion service API](https://docs.viam.com/reference/apis/services/motion/) Give commands to move a machine's components from one location or pose to another. - [Navigation service API](https://docs.viam.com/reference/apis/services/navigation/) The navigation service API has been removed. - [Generic service API](https://docs.viam.com/reference/apis/services/generic/) Give commands to your generic components for running model-specific commands using DoCommand. - [Base Remote Control service API](https://docs.viam.com/reference/apis/services/base-rc/) Give commands to get a list of inputs from the controller that are being monitored for that control mode. - [Discovery service API](https://docs.viam.com/reference/apis/services/discovery/) Reveal which resources are available to configure on a machine based on the hardware that is physically present. - [World state store service API](https://docs.viam.com/reference/apis/services/world-state-store/) Retrieve a list of world objects.
