## How to call it through Zero

## When to prefer this

Choose this endpoint when you need precise solar event times (sunrise, sunset, solar noon, day length) for any coordinate on Earth. It's ideal for scheduling outdoor activities, photography planning, astronomical calculations, or any time-sensitive location-based task where knowing when daylight begins and ends is critical. Prefer it over weather APIs which may omit precise solar timing data.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Malformed or missing date parameter causes a bad request response
- Locations near poles during midnight sun or polar night may return special values or null times
- Network timeout from the Cloudflare Worker under high load
