babon

Kinematics-as-a-service client. Video in, movement data out.

pip install babon

from babon import Babon

Babon("bk_...").analyze("trial.mp4").save("out.zip")

That's it.

A bit more

from babon import Babon

bb = Babon("bk_...")

# get the clinical_report.json dict directly
report = bb.analyze("trial.mp4").data
print(report["gait_parameters"]["gait_velocity_m_s"])

# batch
bb.analyze(["a.mp4", "b.mp4", "c.mp4"]).save("./results/")

# tag with your own identifier
bb.analyze("trial.mp4", label="cohort-3-day-7").save("out.zip")

What's in the bundle

clinical_report.json (gait params, GRF, symmetry), 14 per-joint angle CSVs (ISB convention), raw rotation matrices, 3D joint positions, bodymodel.npz, grf_waveform.json, manifest.json with SHA-256 per file.

Errors

The client raises typed exceptions:

• BabonAuthError — bad key, wrong environment, DPA not accepted.
• BabonQuotaExceeded — monthly limit, concurrent limit, or rate-limited.
• BabonInvalidVideo — file is not a recognised container.
• BabonInvalidLabel — label looks like a real name (ADR-0002).
• BabonRunFailed — pipeline failed.
• BabonTimeout — wait() exceeded its timeout.

All carry .code (the API error code) and .request_id (the support handle).

What we are and are not

• Measurement only. Output is kinematics; clinical interpretation is yours.
• EU-cloud (Scaleway fr-par). Videos never leave the EU.
• Don't put real patient names in label or in your filenames. We reject name-shaped labels server-side.
