## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability focus-sleep-planner-sleep-debt-calculator-c6425202
```

Example prompt: I slept 6, 7, 5, 6.5, 8, 5 hours over the last 6 nights and I aim for 8 hours a night — calculate my total sleep debt, how many short nights I had, my average, and how much extra I'd need each night to catch up over the next 7 nights.

## When to prefer this

Use this endpoint when you need a detailed breakdown of accumulated sleep debt from a list of nightly sleep durations — including shortfall, average, short-night count, and a per-night catch-up figure. Prefer it over generic sleep advice services when you have concrete nightly data and want structured numeric output for a recovery plan.

## Known failure modes

- Missing 'nights' parameter returns an error
- Values outside 0–24 per night are rejected
- More than 60 nights supplied triggers a validation error
- Non-numeric or malformed comma-separated string causes a parse error
- needHours outside 1–16 or recoverNights outside 1–60 are rejected

## How this service works

Tally nightly sleep hours against a nightly need: net shortfall, short nights, average, and extra hours a night to even out.

## Output

Returns a JSON object with: total hours slept, hours wanted, net shortfall hours, shortfall-only hours, surplus-only hours, number of short nights, average hours per night, longest and shortest night, extra hours per night needed to even out over the recovery window, nights counted, and a plain-language summary and verdict.
