# Focus & Sleep Planner – Equal Time Blocks with Breaks

> Focus & Sleep Planner – Equal Time Blocks with Breaks is a paid API for AI agents from focus-sleep-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Splits a time window into equal-length focus blocks separated by breaks, returning each block's start/end times (12-hour clock), block count, leftover minutes, and totals.

## 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-equal-time-blocks-with-breaks-1a2408aa
```

Example prompt: Split my work window from 9:00 AM to 5:00 PM into 50-minute focus blocks with 10-minute breaks, and tell me how many blocks fit and how many minutes are left over.

## When to prefer this

Choose this endpoint when you need to divide any contiguous time window into a fixed-size block schedule with uniform breaks — particularly when you want the exact 12-hour clock times for each block, the leftover minutes, and aggregate focus/break totals. Prefer it over a Pomodoro endpoint when you don't need the classic Pomodoro structure (short + long breaks) and just want equal blocks of any chosen length.

## Known failure modes

- Missing required query params (windowStart, windowEnd, blockMinutes) returns an error
- blockMinutes outside 5–480 range may be rejected
- breakMinutes outside 0–120 range may be rejected
- Malformed time strings (e.g. missing AM/PM) may cause a parse error
- A window too short for even one block returns blockCount 0 with all leftover minutes
- Payment failure (x402) results in a 402 response before computation

## How this service works

Split a time window into equal blocks with breaks between them, with 12-hour clock times and the minutes left over.

## Output

Returns a list of numbered blocks each with a 12-hour start and end time (and day offsets if the window crosses midnight), plus summary stats: total block count, total focus minutes, total break minutes, total window minutes, and leftover minutes that didn't fill a complete block. Also includes a human-readable summary and any disclaimer or degraded-service flags.
