# Saylor Innovations Meeting Planner – Time Zone Overlap Finder

> Saylor Innovations Meeting Planner – Time Zone Overlap Finder is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Finds overlapping working hours across 2 to 8 IANA time zones for a given date, returning UTC windows with local start/end times in each zone and total overlap minutes.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-meeting-planner-time-zone-overlap-finder-6a10d689
```

Example prompt: What working hours overlap between America/New_York, Europe/London, and Asia/Tokyo for 2025-08-15? I want to find a good time to schedule a team call.

## When to prefer this

Choose this endpoint when you need to compute shared working-hour windows across multiple international time zones for scheduling purposes, especially when you need both UTC reference times and localized start/end times in each participant's zone. It handles up to 8 zones simultaneously and returns structured overlap data ready for calendar or notification workflows. Prefer this over manual time zone conversion tools when you need a single call to resolve meeting feasibility for distributed teams.

## Known failure modes

- Fewer than 2 or more than 8 time zones provided — request rejected
- Invalid or unrecognized IANA time zone string — error or null offset returned
- Date format not matching YYYY-MM-DD — may default to today or return an error
- No overlapping working hours exist across the given zones — overlap_found returns false and windows array is empty
- Payment not completed — 402 response with x402 payment challenge

## How this service works

Find overlapping working hours across 2 to 8 time zones for a date - UTC windows with local start and end in each zone and total overlap minutes

## Output

Returns a JSON object containing: the queried date, each time zone with its UTC offset, a boolean indicating whether overlap was found, an array of shared working-hour windows (each with UTC start/end and local times in every zone plus window length in minutes), total overlap minutes, and optional advisory text or caveats about the result.
