API key & exercises - PoseTracker

On the SDK, keypoints work without an API key. Pass apiToken when you want the remote movement engine (exercises, counter, form score, jumps, plan-gated features). The WebView tracking URL always requires token= — WebView quickstart. Get a key at posetracker.com.

Provider with token

import {
  PoseTrackerProvider,
  WebViewPoseView,
  usePoseTracker,
} from '@pose-tracker/react-native-pose-estimation';

function App() {
  return (
    <PoseTrackerProvider
      apiToken="YOUR_API_KEY"
      options={{ features: { angles: true, progression: true, minGrade: 'B' } }}
    >
      <CameraScreen />
    </PoseTrackerProvider>
  );
}

function CameraScreen() {
  const { preload, startExercise } = usePoseTracker({
    onCounter: (e) => {
      console.log(e.count, e.formScore?.grade);
    },
  });

  // startExercise('push_up');

  return (
    <WebViewPoseView
      style={{ flex: 1 }}
      drawSkeleton
      skeletonUuid="OPTIONAL_CUSTOM_SKELETON_UUID"
    />
  );
}

Same pattern with -light and with the web SDKs (createPoseTracker({ apiToken })).

Modes

Mode	When	Events
`keypoints-only`	SDK with no valid API key	Keypoints
`full-engine`	Handshake succeeded + engine loaded	Counter, form score, angles, …

Watermark

Shown for keyless and free plans. Hidden for paid plans (developer, company, enterprise, …). Override with showWatermark on WebViewPoseView.

Reference

For LLMs: SDK keypoints are free; exercises need apiToken. WebView URL always needs token. https://docs.posetracker.com/api-key
