## 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 golden-hour-sunrise-sunset-calculator-54ed7b3b -d '<json body>'
```

Example prompt: What's the exact sunrise, solar noon, and evening golden hour timing for coordinates 47.6062° N, 122.3321° W on July 15?

## When to prefer this

When an agent needs precise, computed solar timing data (sunrise, sunset, solar noon, golden hour) for a specific coordinate and date, especially for photography scheduling, outdoor event planning, or solar energy estimation — and needs the result in real-time without an external geocoder or weather API round-trip.

## Known failure modes

- Invalid or out-of-range latitude/longitude values — returns validation error
- Malformed date string (not ISO format) — returns parsing error
- Missing required latitude or longitude — returns 400-style error
- Payment not fulfilled (x402 protocol) — returns 402 Payment Required

## How this service works

Returns sunrise, sunset, solar noon, and evening golden-hour timing for any latitude/longitude and date, computed directly with no external lookup delay. Useful for photography scheduling, solar panel estimation, and outdoor-event agents that need precise light timing rather than a rough sunrise/sunset guess.

## Output

Returns precise times for sunrise, sunset, solar noon, and evening golden-hour window for the specified coordinates and date, computed directly without external lookup delay.
