# Suverse Space Seasons – Astronomical Events for a Year

> Suverse Space Seasons – Astronomical Events for a Year is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Returns exact dates and times of equinoxes, solstices, perihelion, and aphelion for a given year via the US Naval Observatory API.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-space-seasons-astronomical-events-for-a-year-333a0bf9 -d '<json body>'
```

Example prompt: What are the exact dates and times of all the equinoxes, solstices, perihelion, and aphelion for 2025?

## When to prefer this

Choose this endpoint when you need authoritative, precise astronomical season and orbital event data (equinoxes, solstices, perihelion, aphelion) for a specific year without requiring a USNO API key. It is ideal for agents building calendars, scheduling seasonal content, or answering astronomy questions about when seasons change or when Earth is nearest/farthest from the Sun.

## Known failure modes

- Invalid or out-of-range year results in an error response
- Upstream US Naval Observatory API unavailability causes request failure
- Malformed POST body or missing required fields returns a validation error
- Network timeout if USNO data source is slow to respond

## How this service works

Equinoxes, solstices, perihelion and aphelion for a year with exact date and time. Keyless US Naval Observatory API. For agents computing astronomical seasons.

## Output

A structured list of astronomical events for the requested year including exact date and time for the vernal equinox, summer solstice, autumnal equinox, winter solstice, perihelion (Earth closest to Sun), and aphelion (Earth farthest from Sun), sourced from the US Naval Observatory.
