WhenPeak, performance timing from sleep

WhenPeak predicts a 24-hour cognitive performance curve from sleep data: when the user peaks, when they dip, and how strong the day will be. The value is timing, the peak windows and the dip, not the score. Lead every answer with timing.

This skill uses WhenPeak's public endpoints, which need no account and no API key.

Requirements

• Network access to api.whenpeak.com
• Python 3 (standard library only, no installs)

If the environment cannot reach api.whenpeak.com, say so plainly and point the user to whenpeak.com. Never fabricate a prediction or a curve.

Workflow

1. Collect last night's sleep
