How this service works
Latest 1-minute estimated planetary Kp index from NOAA SWPC, with a boolean storm flag (estimated_kp >= threshold, default 5 = G1 storm). Query: ?last=1..60 (trailing minutes returned in 'series'), ?threshold=0..9. Signals GPS/GNSS degradation, satellite drag, HF blackouts and grid stress. 60s cache.
Output
Returns the current Kp index value, estimated Kp, timestamp, a storm boolean (true if Kp meets or exceeds threshold), and an optional time-series array of up to 60 trailing 1-minute values, sourced from NOAA SWPC.
Example use cases
Example prompt
“What's the current NOAA Kp index? Give me the last 5 minutes of readings and flag it as a storm if Kp hits 6 or above.”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/space/kpWhen to prefer
Use this endpoint when you need real-time or near-real-time NOAA Kp geomagnetic index data with a simple storm flag, especially in agentic workflows that already support x402 micropayments. Prefer this over scraping NOAA directly when you want a clean JSON response with a configurable storm threshold and trailing time series, with pay-per-call pricing and no subscription required.
Side effects
- HTTP 402 returned if payment not included — endpoint requires USDC payment via x402 protocol before data is served
- Invalid 'last' parameter outside 1-60 range may return an error or clamped value
- NOAA upstream outage may cause stale or unavailable data
- Threshold value outside 0-9 range may cause validation error
