# Query Params details

**Canonical endpoint**

```
GET https://app.posetracker.com/pose_tracker/tracking?token=...&exercise=...
```

***

### Minimum required URL (real-time)

```
https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY&exercise=squat
```

***

### Query parameters

The full parameter reference is maintained here:

* **Shared query parameters (Tracking + Upload Tracking)**

#### Important real-time parameters

* `token` (required)
* `exercise` (required)
* `placement`, `postureBox`, `placementCountdownSeconds` (recommended)
* Optional: `minGrade` (repetition exercises only)

***

### minGrade (optional, repetition exercises only)

Use `minGrade` if you want PoseTracker to **only count “valid” reps**.

Example:

```
https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY&exercise=squat&minGrade=B
```

* Counts only reps graded **A or B**
* Does not count reps graded **C, D, or F**
* Ignored for duration and custom exercises

> The grade is sent inside the `counter` event as `counter.form_score.grade`.

***

### Typical realtime message flow

1. `initialization`
2. `posture` (placement) until ready + optional countdown
3. `counter` (on each counted rep)
   * includes `form_score` for the rep that was just counted
4. optional outputs (plan-gated): `progression`, `recommendations`, `keypoints`, `angles`
5. `error` at any time

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://posetracker.gitbook.io/posetracker-api/use-posetracker-on-real-time-camera-webcam/query-params-details.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
