# Agent Time & Place – Sun Times

> Agent Time & Place – Sun Times is a paid API for AI agents from time-place.agent-utils.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns sunrise, sunset, moon phase, day length, and current sun position for a given latitude/longitude and date

## 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 agent-time-place-sun-times-ce0f8f81
```

Example prompt: What time does the sun rise and set in Oslo (lat 59.9139, lon 10.7522) on June 21, 2026, and how long is the day?

## When to prefer this

Choose this endpoint when you need deterministic, sub-cent astronomical solar and lunar data for a specific geographic coordinate without requiring API key registration — payment via x402 is the only authentication needed. It is ideal for agents that need sunrise/sunset, moon phase, day length, or current sun position in a single lightweight call. Prefer it over general weather APIs when you specifically want solar timing data rather than forecasts, and over heavy astronomy libraries when you need a hosted, pay-per-call solution with no setup overhead.

## Known failure modes

- Missing required lat or lon parameter returns a 400 error
- Latitude outside -90 to 90 or longitude outside -180 to 180 returns validation error
- Invalid date format (non-ISO 8601) returns a 400 error
- Payment not provided or insufficient returns 402 Payment Required
- During polar day or polar night, sunrise/sunset times may be null and polar field set accordingly
- Network timeouts or upstream worker failures return 5xx errors

## How this service works

Geocoding, timezones, holidays, business days, sun times, FX and distances for AI agents. Deterministic, sub-cent, no API key: payment is authentication (x402).

## Output

A JSON object containing: local and UTC times for sunrise and sunset, total day length in minutes (null during polar events), a polar field indicating polar day/night/none, moon phase fraction and name and illumination percentage, current sun azimuth and altitude in degrees, the resolved timezone, and the echo of the input lat/lon/date.
