# Hebbian Robotics Data Quality API

> Evaluate data quality without training a robotics model.

The Hebbian Robotics Data Quality API turns Physical AI footage into queryable
measurements. Use it to build quality-control workflows, compare dataset
coverage and composition, find collection gaps, and make evidence-based
decisions about footage intended for training.

The service returns measurements rather than a universal score or verdict. You
choose the thresholds and actions that fit your capture setup.

## Endpoints

| Endpoint | Use it to |
| - | - |
| `GET /api/v1beta/access` | Check the scope and capabilities of a bearer token. |
| `GET /api/v1beta/quality/datasets` | List the datasets you can read and their available quality metrics. |
| `GET /api/v1beta/quality/video-characteristics` | How much video is black, frozen, clipped, blurry, unstable, or unreadable. |
| `GET /api/v1beta/quality/hand-activity` | Measured hand visibility, active manipulation, and hand-object contact. |
| `GET /api/v1beta/quality/content-diversity` | Observed environments, visible and interacted objects, action verbs, task contexts, and object-action pairs. |
| `GET /api/v1beta/quality/duplicates` | How much of the footage is the same footage more than once. |

[API reference](/api-reference/overview).

[Understand quality metrics](/quality-metrics) defines response conventions;
[Build a quality-control check](/quality-control) shows how to combine selected
measurements without prescribing your acceptance policy.
