Space weather API — solar storms, live.

The current space-weather now-cast — NOAA R/S/G storm scales, the Kp index and solar-wind speed and density.

The call

Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.

# REST (free key)
curl -H "X-API-Key: $KEY" "https://dynamicfeed.ai/space-weather"

# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call:
space_weather()

Sample response

{ "kp": 5, "scales": {"R":1,"S":0,"G":1}, "solar_wind_kms": 540,
  "observed_at": "2026-06-03T12:30:00Z" }

Why live data

Geomagnetic conditions change by the hour and drive real risk to satellites, power grids and HF radio — none of it in a model's training data.
