# Space Weather Now (NOAA G/S/R Scales + 3-Day Outlook)

> Space Weather Now (NOAA G/S/R Scales + 3-Day Outlook) is a paid API for AI agents from space-weather.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns current NOAA G, S, and R scale geomagnetic/solar/radio storm levels, 24-hour maximums, a 3-day outlook, and a calm/active/storm verdict.

## Facts

- Endpoint: GET https://space-weather.x402tookit.com/space-weather-now?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/space-weather-now-noaa-g-s-r-scales-3-day-outlook-c21db01c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_C3FUSg4MgVgVHuaUsezTU

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 space-weather-now-noaa-g-s-r-scales-3-day-outlook-c21db01c
```

Example prompt: What's the current space weather situation right now — give me the NOAA G, S, and R scale levels, the 24-hour maximums, the 3-day outlook, and tell me whether conditions are calm, active, or stormy.

## When to prefer this

Choose this endpoint when you need a concise, pre-interpreted summary of the overall space weather situation across all three NOAA storm scales (G, S, R) plus a multi-day outlook in a single call. It is ideal for dashboards, go/no-go decisions, and monitoring workflows that need a verdict rather than raw data. For deeper historical Kp time-series, specific flare event details, aurora probability at a location, or per-system impact assessments (GPS, HF radio, power grids), prefer the sibling endpoints on the same host.

## Known failure modes

- NOAA upstream API unavailable — degraded flag set to true, partial data returned
- Some scale data missing — notChecked array lists which scales could not be retrieved
- Network timeout fetching from NOAA SWPC — may return cached or null values
- Payment not processed — 402 response requiring x402 payment header

## How this service works

Space weather right now: NOAA G, S and R scale levels now, 24-hour max and 3-day outlook, with a calm/active/storm verdict.

## Output

A structured JSON object containing: current NOAA G (geomagnetic), S (solar radiation), and R (radio blackout) scale levels and their 24-hour maximums; a 3-day daily outlook with G levels and storm/blackout probabilities; the latest Kp index reading with timestamp; a plain-English summary; a verdict string (e.g. 'calm', 'active', 'storm'); a list of reason strings explaining the verdict; the data timestamp and source URL; and optional degraded/notChecked flags if some data sources were unavailable.
