## 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 northline-sun-events-api-65fa856c
```

Example prompt: What time is sunrise and sunset tomorrow at latitude 47.6062, longitude -122.3321?

## When to prefer this

Choose this endpoint when you need accurate solar event times (sunrise, sunset, twilight phases) for a specific geographic coordinate and date, especially in an agentic context where pay-per-call with no account setup is preferable. Ideal for low-frequency, precise lookups rather than bulk historical datasets.

## Known failure modes

- Missing or invalid latitude/longitude returns an error response
- Out-of-range date values may return no data or an error
- Network or payment failure (x402) results in 402 Payment Required if USDC payment is not submitted
- Extreme polar latitudes where the sun doesn't rise or set may return special values or null for certain events
