# Saylor Innovations Aurora Visibility Forecast

> Saylor Innovations Aurora Visibility Forecast is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Returns NOAA OVATION model aurora visibility probability (percent chance, strongest nearby value, and equatorward edge latitude) for any latitude/longitude coordinate.

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 saylor-innovations-aurora-visibility-forecast-7dd18266
```

Example prompt: What are the chances of seeing the northern lights tonight at latitude 64.84, longitude -147.72? Give me the OVATION model probability and the equatorward edge latitude.

## When to prefer this

Choose this endpoint when you need a quick, per-coordinate aurora visibility probability directly from the authoritative NOAA OVATION model, including the equatorward edge latitude and strongest nearby value — useful for aurora hunting apps, travel planning, or automated space-weather alerts at a specific location. Prefer over general space-weather APIs when you need a probability percentage tied to exact coordinates rather than a broad Kp-index-based regional estimate.

## Known failure modes

- Missing required lat or lon parameters returns an error
- Out-of-range latitude (outside -90 to 90) or longitude (outside -180 to 180) may cause a validation error
- aurora_probability_percent or equatorward_edge_latitude_at_longitude may return null if NOAA data is unavailable or the location is outside model coverage
- NOAA OVATION model data may be stale during space weather data outages

## How this service works

Aurora visibility probability for any lat/lon from the NOAA OVATION model - percent chance, strongest nearby value and equatorward edge latitude

## Output

A JSON object containing the aurora probability as a percentage at the queried coordinates, the strongest aurora probability within 3 degrees, the equatorward edge latitude at the given longitude, forecast and observation timestamps, a visibility label, the data source attribution, and any contextual notes or caveats about the reading.
