# NOAA Geomagnetic Storm & Space Weather API

> NOAA Geomagnetic Storm & Space Weather API is a paid API for AI agents from api.paylyte.ai, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-30).

Returns current geomagnetic storm level (Kp index) and active space weather alerts from NOAA

## Facts

- Endpoint: GET https://api.paylyte.ai/v1/data/space/weather?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/noaa-geomagnetic-storm-space-weather-api-6477ad06
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7lzgkqqtXC5dwZfh9OPLF

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-geomagnetic-storm-space-weather-api-6477ad06
```

Example prompt: What is the current geomagnetic storm level and are there any active NOAA space weather alerts right now?

## When to prefer this

Choose this endpoint when you need current geomagnetic storm conditions and NOAA space weather alerts in a single, low-latency call without having to query NOAA directly. It is ideal for agents that need to monitor solar activity, check aurora visibility conditions, or assess risk to satellite/power infrastructure. The x402 micropayment model makes it suitable for on-demand agent use without subscription overhead.

## Known failure modes

- NOAA upstream unavailable — API may return an error or stale data if NOAA source is unreachable
- No active alerts — alerts array will be empty during quiet space weather periods (not an error)
- Rate limiting or payment failure — 402 Payment Required if x402 payment is not processed
- Stale data — retrievedAtUtc may lag real-time if caching is in effect

## How this service works

Current geomagnetic storm level and space weather alerts from NOAA, the National Oceanic and Atmospheric Administration.

## Output

Returns a JSON object containing the current geomagnetic storm tier (e.g. G0–G5), the Kp index value object, a list of active space weather alerts, timestamps for when data was retrieved and as-of time, the NOAA source URLs for the data and alerts, and an explanatory note about the data.
