Ask your own assistant about your athletes

Give the key to the assistant you already use and ask in plain words: who missed a session this week, whose fatigue is climbing, how the long run went. It reads the answer from your real data, not from a screenshot you pasted.

The whole calendar in one request

Planned and completed side by side for any athlete and any dates: duration, distance, heart rate, power and load, plus zones, fitness and form, sleep and weight. Always in the same units, ready for a report or a dashboard of your own.

Plan from wherever you work

A key with write access can add workouts with their intervals, copy sessions from your library, add notes and races, and comment on a session. The athlete is notified and sees it on their calendar, exactly as if you had done it in the app.

Your keys, your rules

Create a key for each tool, read-only unless you decide otherwise. See when each one was last used and revoke it whenever you want. A key only ever reaches your own athletes.

Included in the Elite plan

No extra charge and no separate product: the API comes with the Elite plan, free trial included. Request access in Settings, tell us what you want to build and we reply within two working days. Developers get a full OpenAPI description to build against.
