# Space Weather HF/GPS/Satellite/Power Grid Impact

> Space Weather HF/GPS/Satellite/Power Grid Impact is a paid API for AI agents from space-weather.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-21).

Returns the current impact of space weather on HF radio, GPS accuracy, satellites, and power grids, with the NOAA storm level driving each effect.

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-hf-gps-satellite-power-grid-impact-bf84bc4a
```

Example prompt: What does the current space weather mean for HF radio, GPS accuracy, satellites, and power grids right now — and what storm levels are driving each?

## When to prefer this

Choose this endpoint when you need a synthesized, plain-language interpretation of how space weather is currently affecting practical systems (HF radio, GPS, satellites, power grids) rather than raw NOAA indices. It is ideal for operators, automation systems, or agents that need actionable impact assessments without parsing raw Kp, G, S, or R scale values themselves. Prefer sibling endpoints if you need raw Kp history, aurora probability, sunspot data, or multi-day forecasts.

## Known failure modes

- NOAA data unavailable — upstream fetch failure returns null fields
- All impact fields may be null if the space weather data source is temporarily unreachable
- Stale data if NOAA updates are delayed — check asOf timestamp
- notChecked array may list domains that could not be evaluated

## How this service works

What current space weather means for HF radio, GPS accuracy, satellites and power grids, with the level driving each.

## Output

A structured object containing plain-language impact assessments for HF radio, GPS, satellites, and power grids; a degraded boolean flag; the driving NOAA G, S, and R scale levels as numbers; the latest solar flare class; a list of reasons for any degradation; an overall verdict and summary; the data timestamp (asOf); source name and URL; and a disclaimer.
