## 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 suverse-moon-phases-api-51ba84b1 -d '<json body>'
```

Example prompt: What are the upcoming primary moon phases starting from today — give me the exact dates and times for the next New Moon, First Quarter, Full Moon, and Last Quarter.

## When to prefer this

Choose this endpoint when you need authoritative, precise lunar phase times sourced from the US Naval Observatory without requiring an API key. It is ideal for astronomy agents, gardening apps, tide planners, or any use case needing exact New/First Quarter/Full/Last Quarter moon timestamps starting from a given date.

## Known failure modes

- Invalid or missing date input returns an error response
- Date far in the future may exceed USNO data availability
- Network or proxy timeout if upstream USNO API is unavailable
- Malformed request body returns 400-level error
- Payment failure via x402 protocol blocks the call
