## 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 sun-times-sunrise-sunset-api-8701907f
```

Example prompt: What time is sunrise and sunset today, and how long is the day in total?

## When to prefer this

Choose this endpoint when you need quick, no-account-required solar time lookups paid per call in USDC via x402, and do not need to specify a custom latitude/longitude (endpoint uses a default location). Ideal for lightweight agents that need ephemeris data without API key management.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Network unreachability to duckdns.org host — connection timeout
- Server-side solar computation error — may return 500
- No query parameters accepted; passing unexpected params may be silently ignored or error
