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 api-strale-io-13da305d
```

Example prompt: Find the best meeting times for participants in America/New_York, Europe/London, and Asia/Tokyo — we want a 60-minute slot during preferred hours of 09:00-17:00, ranked by fairness for everyone.

## When to prefer this

Use this endpoint when you need an algorithmic, fairness-ranked recommendation of meeting times across multiple IANA time zones, especially for globally distributed teams where no single participant should consistently bear unsociable hours. Prefer it over manual calendar tools when you want quantified fairness scoring rather than just overlap detection.

## Known failure modes

- Invalid or unrecognized IANA timezone names return an error
- No overlapping slots found when preferred hours don't intersect across time zones
- Missing required 'timezones' query parameter returns 400
- Only one timezone provided yields trivially unranked results
- Malformed preferred_hours format (not HH:MM-HH:MM) may cause parse errors

## How this service works

Find optimal meeting times across time zones. Returns ranked slots by fairness, with local times for each participant. Algorithmic.

## Output

A ranked list of meeting slot candidates with fairness scores, showing the proposed UTC time and the corresponding local time for each participant's timezone, ordered from most to least equitable for all attendees.
