Environmental Data API & MCP Server
Intelligence
for Life
Pxie is an environmental data API and MCP server for space weather, aurora, power grids, oceans, soil and the night sky. Canadian owned and operated, built to protect infrastructure and inform decisions.
The signals that shape
our world.
Space Weather
Storm levels, a 3-day outlook, solar flares, solar wind and eruption arrival times, in plain terms.
Coverage: Global
Learn more →Aurora Forecast
Tonight's aurora chance at any location, the live aurora oval and substorm timing.
Coverage: Global, both hemispheres
Learn more →Ground Magnetometers
Live readings from ground stations worldwide and a local storm level for any point.
Coverage: Global; most detailed near a station
Learn more →Energy Grid
Geomagnetic storm risk per substation and line, with a plain-language action checklist.
Coverage: Anywhere on Earth; most detailed in Canada
Learn more →Ocean & Marine
Daily sea surface temperature, the difference from normal and sea-ice cover for any ocean point.
Coverage: Global ocean
Learn more →Soil & Agriculture
Soil properties, management zones, soil moisture and growing-season climate for any field.
Coverage: Farmland and open ground worldwide
Learn more →Sky Quality
Cloud cover, transparency and seeing up to 72 hours ahead, an observing score and light pollution.
Coverage: Global
Learn more →Astronomy
Moon phase, sunrise, sunset and twilight for any coordinates and date.
Coverage: Global, any date
Learn more →Freshwater & Air Quality
We're building harmful algal bloom and toxin risk for lakes and rivers, plus hyperlocal air quality and wildfire smoke. Join the early-access list to hear first.
Coverage: Planned

Designed for impact.
We handle the complexity of sourcing, normalizing, and delivering planetary data so your team can focus entirely on what you build with it.
Global Coverage
Most endpoints answer for any latitude and longitude on Earth, and every vertical states exactly where its data applies. No guessing about coverage.
Authoritative Sources
We ingest exclusively from government agencies, research networks, and certified sensor grids. No synthetic data without clear labelling.
One API, Every Vertical
One key, one dashboard, one consistent schema across every domain. Less time on plumbing, more time on product.
Built for MCP
A live MCP server across every active vertical, letting AI assistants call environmental and space weather data inside conversations and agent workflows.
The Pxie MCP server:
your AI's data layer.
The Pxie MCP server lets compatible AI assistants call live environmental and space weather data in real time, mid-conversation, without custom integration work for each assistant.
This opens an entirely new channel for your data. Not just developers building apps — AI assistants themselves become your consumers, pulling Pxie signals into answers, reports, and autonomous agent workflows.

Environmental data API questions.
What is an environmental data API?
An API that delivers environmental measurements and forecasts as clean data. Pxie covers space weather, aurora, power grid storm risk, ocean, soil, sky quality and astronomy.
Is there a free space weather API?
Yes. The free Pxie plan includes the current geomagnetic storm level, solar flares, light pollution and moon, sun and darkness data.
What is the Pxie MCP server?
A hosted Model Context Protocol server that lets Claude, ChatGPT and other AI assistants call Pxie data as tools. It is included from the Builder plan.
