## 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 sitecheck-sun-moon-position-lookup-3c8f1a07
```

Example prompt: What time is sunrise and sunset in Berlin (52.52, 13.405) on October 14, 2026, and what moon phase will it be?

## When to prefer this

Choose this endpoint when you need accurate, per-coordinate sunrise/sunset/solar noon and moon phase data for any date and location worldwide. It is especially useful when you need both solar and lunar data in a single call. Backed by MET Norway (a trusted meteorological source), it is suitable for scheduling, photography planning, agricultural timing, or any use case requiring precise astronomical times at a geographic point.

## Known failure modes

- Missing lat or lon parameters returns a validation error
- Latitude outside -90 to 90 or longitude outside -180 to 180 causes rejection
- Invalid date format (not YYYY-MM-DD) may return an error or default to today
- Polar regions during midnight sun or polar night return null for some sun fields
- Upstream MET Norway API unavailability causes service failure

## How this service works

Sunrise, sunset, solar noon and day length for a coordinate and date (default today), with the moonrise, moonset and phase. Times are ISO 8601 with the offset MET Norway gives (+00:00 is UTC). Attribution: data from MET Norway (CC BY 4.0).

## Output

A JSON object containing: sunrise and sunset times in ISO 8601 format with UTC offset, solar noon time, day length in decimal hours, moon phase name (e.g. 'waxing crescent'), phase degrees, moonrise and moonset times, plus metadata including source attribution (MET Norway CC BY 4.0) and a checkedAt timestamp.
