## 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 classroom-time-block-scheduler-b00455f8 -d '<json body>'
```

Example prompt: Can you schedule my classroom tasks today — Draft for 40 minutes, Review for 20 minutes, and Practice for 30 minutes — starting at 09:00 with 5-minute breaks between each?

## When to prefer this

Choose this endpoint when you need to convert an ordered list of classroom or educational tasks into a concrete timed schedule with automatic breaks inserted between tasks. It is best suited for structured, sequential educational workflows where tasks have known fixed durations and a fixed start time. Prefer this over generic calendar or meeting scheduling tools when the focus is simple sequential time-blocking without room reservations, attendees, or calendar integration.

## Known failure modes

- Invalid start time format — must be a valid HH:MM string
- Tasks array is empty or malformed — each task object must include a task name and minutes field
- Negative or zero break_minutes value causing invalid schedule computation
- Very large number of long tasks potentially producing schedules extending past midnight or across day boundaries

## How this service works

Classroom Time-block scheduler: Place tasks into sequential time blocks with breaks. Tailored for classroom workflows.

## Output

Returns a list of sequentially ordered time blocks, each specifying the task name, its start time, and its end time, with break slots inserted between tasks according to the specified break duration.
