How this service works
244 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.
Output
Returns a JSON object with: current Kp index (number), geomagnetic storm level (e.g. G0–G5), maximum recent Kp, Kp readings over recent 3-hour intervals, solar wind speed in km/s, a list of recent solar flares with class and timestamps, active NOAA space weather warnings with full message text and issue times, a note explaining the Kp scale, and the data source attribution.
Example use cases
Aurora visibility check before trip
“Is there a geomagnetic storm strong enough to see the northern lights tonight? Give me the current Kp index and storm level.”
Satellite operations risk assessment
“Pull the latest space weather data — Kp index, storm level, solar wind speed, and any NOAA warnings — so I can assess risk for our satellite operations right now.”
Solar flare activity monitoring
“Have there been any significant solar flares recently, and what is the current geomagnetic storm level and Kp index?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/space-weather?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need current, real-time space weather conditions sourced directly from NOAA SWPC, especially Kp index, geomagnetic storm classification, solar wind, and flare data — all in a single structured call. Prefer over scraping NOAA directly or using general web search when you need structured numeric data for programmatic use.
Side effects
- NOAA upstream data unavailable — may return null fields or partial data
- Network timeout if NOAA SWPC feed is slow
- Empty warnings array when no active alerts exist (not an error)
- Malformed request body may return 400 error
