## 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 eu-weather-geo-sunrise-sunset-a32dfaf7
```

Example prompt: What time does the sun rise and set in Lyon, France on June 21, 2026, and how many minutes of daylight will there be?

## When to prefer this

Choose this endpoint when you need precise local sunrise/sunset times or day length for a specific city or coordinate on a specific date, paid per-call in USDC without requiring an account or API key. It is ideal for lightweight, on-demand astronomical lookups without the overhead of a subscription service.

## Known failure modes

- City not found or population below 50k threshold — 404 or empty result
- Ambiguous city name without country code — wrong city returned
- Invalid date format (not YYYY-MM-DD) — 400 validation error
- Missing both city and lat/lon — 400 missing parameter error
- Payment failure via x402 — 402 response, no charge applied

## How this service works

Weather and geo utilities for AI agents, paid per call in USDC via x402 (no account, no API key): current weather and up-to-9-day daily forecasts for any city or lat/lon (MET Norway open data, CC BY 4.0), city geocoding with time zones (GeoNames, CC BY 4.0) and sunrise/sunset. Errors are never charged.

## Output

A JSON object with the date, local sunrise datetime, local sunset datetime, and total day length in minutes for the requested location and date.
