# Space Weather Intelligence – Alerts

> Space Weather Intelligence – Alerts is a paid API for AI agents from space-weather.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Returns the newest NOAA SWPC geomagnetic and solar-flare alert messages, sorted deterministically by product-code kind, with complete message digests and freshness metadata.

## Facts

- Endpoint: GET https://space-weather.use.x402atlas.com/alerts
- Price: $0.005/call
- Payment: x402
- Status: unknown

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-intelligence-alerts-f04da1b8
```

Example prompt: Pull the latest NOAA space weather alerts — give me up to 10 of the newest geomagnetic and solar-flare messages along with how fresh the data is.

## When to prefer this

Choose this endpoint when you need the latest raw NOAA SWPC geomagnetic and solar-flare alert messages with deterministic sorting and freshness metadata. Prefer this over the sibling conditions or forecast endpoints when you specifically want alert-level notifications (storm watches, warnings, summaries) rather than numerical Kp-index values or multi-day forecasts. Ideal for monitoring pipelines, risk assessment workflows, or any agent that needs to react to breaking space weather events.

## Known failure modes

- NOAA SWPC upstream unavailable — stale flag set to true with cached data returned if available
- limit parameter out of range (below 1 or above 50) — validation error
- No alerts currently available from NOAA — empty alerts array returned
- Network timeout reaching space-weather.use.x402atlas.com — HTTP 5xx error
- Payment not provided or insufficient — HTTP 402 payment required

## How this service works

Space-weather alerts — newest bounded NOAA SWPC geomagnetic and solar-flare messages with deterministic product-code kinds, complete-message digests, and freshness.

## Output

A JSON object containing an array of the newest NOAA SWPC alert messages (up to the requested limit, default 20, max 50), each with a product-code kind and complete message digest. Also includes a normalized query object, a boolean stale flag indicating if a cached snapshot was used, source age in seconds, any warnings, and Atlas documentation metadata.
