# Suverse Astronomy UV Index Daily Forecast

> Suverse Astronomy UV Index Daily Forecast is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.055/call, status unknown (last checked 2026-09-14).

Returns daily maximum UV index and sunshine duration forecast for any global coordinate using Open-Meteo, with no API key required.

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-astronomy-uv-index-daily-forecast-70070ddd -d '<json body>'
```

Example prompt: What's the daily max UV index and sunshine duration forecast for the next 7 days at coordinates 51.5074° N, 0.1278° W — I need to plan some outdoor events in London and want to know the safest windows for sun exposure.

## When to prefer this

Choose this endpoint when you need keyless, globally available UV index and sunshine-duration forecasts tied to precise GPS coordinates without managing your own Open-Meteo integration. It is ideal for sun-safety agents, solar yield calculators, or outdoor planning tools that need timezone-aware daily UV data in a single paid call rather than building raw Open-Meteo API wrappers.

## Known failure modes

- Invalid or out-of-range coordinates (latitude outside -90 to 90, longitude outside -180 to 180) result in an error response
- Malformed request body or missing required fields returns a 400-level error
- Open-Meteo upstream outage may cause delayed or failed responses
- Requests failing x402 payment verification will be rejected before data is returned
- Timezone resolution issues for edge coordinates near international date line may yield unexpected date alignment

## How this service works

Daily max UV index and sunshine-duration forecast for any coordinate from Open-Meteo. Keyless, global, time-zone aware. Useful for sun-safety, solar yield and outdoor-planning agents.

## Output

Returns a time-zone aware daily forecast array containing the maximum UV index and total sunshine duration for each day at the specified coordinate, sourced from Open-Meteo's global model. No authentication token is required.
