# NOAA Space Weather Scales – Current Levels & 3-Day Forecast

> NOAA Space Weather Scales – Current Levels & 3-Day Forecast is a paid API for AI agents from fittings.sh, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns the current NOAA G (geomagnetic), S (solar radiation), and R (radio blackout) space weather scale levels along with three-day probability forecasts.

## 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 noaa-space-weather-scales-current-levels-3-day-forecast-4a334441
```

Example prompt: What are the current NOAA space weather scale levels for geomagnetic storms, solar radiation, and radio blackouts, and what are the three-day forecast probabilities?

## When to prefer this

Use this endpoint when you need real-time NOAA-official space weather scale levels (G/S/R) and short-term probabilistic forecasts without having to parse raw SWPC feeds directly. Prefer it over general web scraping when you need clean structured data about current storm severity and near-term risk probabilities.

## Known failure modes

- SWPC upstream outage or data feed delay resulting in stale or unavailable data
- Network timeout if NOAA API is slow to respond
- Empty or null scale levels when no active space weather events are occurring

## How this service works

Current NOAA G, S and R space weather scale levels with the three-day forecast probabilities.

## Output

A structured response containing the current active NOAA space weather scale levels (G1–G5 geomagnetic, S1–S5 solar radiation, R1–R5 radio blackout) and the three-day probability forecasts for each scale level, sourced from NOAA's Space Weather Prediction Center (SWPC).
