Space Weather API
Stay ahead of
solar storms.
Pxie's space weather API turns live solar and geomagnetic data into clear answers, so satellites, flights and field crews keep working when the Sun acts up.
Coverage: Anywhere on Earth, both hemispheres.
What the space weather API covers.
Geomagnetic storms
Current storm level on a 0 to 9 scale and a 3-day outlook, so schedules change days ahead.
Solar wind
Real-time speed and density upstream of Earth, plus a 96-hour speed outlook.
Flares and solar eruptions
Recent flares with class and timing, and arrival windows for Earth-directed eruptions.
Radiation belt data
The latest energetic electron levels around Earth by energy threshold, for satellite operators.
One space weather API, matched to the job.
Satellites, drones and positioning
Storm level and the 3-day outlook show satellite and drone operators which days to avoid risky maneuvers, passes and long flights. The radiation belt feed adds the latest energetic electron levels by energy threshold, so spacecraft teams can see when the environment around Earth turns hostile.
Aviation and polar routes
Solar flares arrive with a class and a time, so flight planners can see when a radio blackout may affect high-frequency communication on the sunlit side of Earth. The storm outlook supports polar route planning days ahead instead of minutes before departure.
Surveying, farming and offshore crews
Precision positioning gets worse when the upper atmosphere is disturbed. A daily look at storm level and solar wind tells survey, precision-farming and offshore teams when to expect poorer satellite accuracy and when to move critical work.
Power and pipeline operators
Large storms can push stray current through power lines and pipelines. The same storm data feeds Pxie's geomagnetic disturbance monitoring, which turns it into a risk level for each substation and is currently in testing.
Apps, dashboards and AI assistants
Everything comes back as clean JSON with plain-language labels, and the same data is available to Claude, ChatGPT and other assistants through the Pxie MCP server. A product can answer "is a storm coming this week?" without building its own space weather pipeline.
Research, insurance and reporting
Kp, Dst and other geomagnetic indices are available alongside the storm level, so researchers, insurers and reporting teams can document what a storm did and when, using the same feed that drives live decisions.
The same call, anywhere
Everything is global, so one integration works for a fleet in Canada, a vessel at sea or a ground station on another continent.

Space weather API questions.
Is there a free space weather API?
Yes. The free plan includes the current storm level and solar flares. Outlooks, solar wind and eruption arrival times are on the Builder plan.
Where can I get radiation belt data?
Pxie returns the latest energetic electron levels in Earth's radiation belts by energy threshold, on the Builder plan.
How much warning does it give?
Eruptions usually take one to three days to arrive, and Pxie gives an arrival window once one is detected. Solar wind measured upstream gives roughly 30 to 60 minutes of notice.
Does it work outside North America?
Yes. Storm levels and outlooks are global, and location-based answers accept any latitude and longitude.
