# orbit Geo & Time: Sunrise & Sunset

> orbit Geo & Time: Sunrise & Sunset is a paid API for AI agents from orbit-geo.orbit-builder.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Returns sunrise, sunset, solar noon (with elevation), and day length for any location and date using MET Norway's Sunrise 3.0 API

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 orbit-geo-time-sunrise-sunset-9a9a55ec
```

Example prompt: What time does the sun rise and set in Almaty, Kazakhstan tomorrow, and how long will the day be? Show times in UTC+5:00.

## When to prefer this

Choose this endpoint when you need authoritative solar timing data (sunrise, sunset, solar noon, day length, sun elevation) for any geographic point or named place on a specific date, especially when you need output in a specific UTC offset. It is backed by MET Norway's Sunrise 3.0 API and handles edge cases like polar day/night gracefully. Prefer it over generic weather APIs when the primary need is solar event timing rather than meteorological data.

## Known failure modes

- Invalid or unrecognizable place name returns an error or falls back to example input
- Coordinates outside valid ranges (lat -90 to 90, lon -180 to 180) may cause errors
- Malformed date string (not YYYY-MM-DD) may return an error or use today's date
- Polar regions during midnight sun or polar night return null sunrise/sunset times with a note
- Invalid UTC offset format may cause incorrect time conversion or error
- No parameters provided runs example input rather than returning an error

## How this service works

Location and time data for agents: weather now + 7-day forecast (MET Norway), geocoding and reverse geocoding (OpenStreetMap Nominatim), sunrise/sunset, world time-zone conversion and public holidays (Nager.Date). Real open data fetched at call time, attribution included. $0.001 per call. By orbit-builder.

## Output

A JSON object containing the date, sunrise time, sunset time, solar noon time, solar noon elevation in degrees, day length as a human-readable string (e.g. '8h13m'), and the resolved location coordinates. For polar day or polar night, times are returned as null with an explanatory note.
