# NOAA Planetary K-Index (Geomagnetic Storm Level)

> NOAA Planetary K-Index (Geomagnetic Storm Level) is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns the current NOAA planetary K-index value indicating geomagnetic storm intensity, which drives auroral activity and GPS/radio disruption.

## Facts

- Endpoint: POST https://clonecho.builda.company/x402/geomagnetic-kp
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/noaa-planetary-k-index-geomagnetic-storm-level-cd34973a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_RGvtluyr-mPzVdgK1F08Q

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-planetary-k-index-geomagnetic-storm-level-cd34973a -d '<json body>'
```

Example prompt: What's the current NOAA planetary K-index — I want to know if there's a geomagnetic storm strong enough to see auroras or disrupt GPS right now?

## When to prefer this

Use this endpoint when you need real-time geomagnetic storm activity data for aurora visibility forecasting, GPS disruption assessment, or space weather monitoring. It wraps the authoritative NOAA planetary K-index source in a simple paid API call, ideal for agents that need current Kp without building their own NOAA integration.

## Known failure modes

- NOAA upstream data source unavailable — returns error or stale data
- Payment required error (402) if USDC payment not attached
- Network timeout if NOAA feed is slow to respond
- Rate limiting if called too frequently

## How this service works

SCIENCE: NOAA planetary K-index — geomagnetic storm level driving auroras & GPS disruption. Returns JSON.

## Output

A JSON object containing the current planetary K-index value (Kp), which ranges from 0 (quiet) to 9 (extreme storm), along with associated geomagnetic storm level information sourced from NOAA.
