How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns a JSON object with the OVATION model's aurora visibility probability (0-100%) at the nearest 1-degree grid point, a qualitative likelihood label (e.g. 'low', 'medium', 'high'), current Kp index and NOAA G-scale, sun altitude in degrees, a dark_enough boolean (true if sun is below -12°), model forecast time and observation time, staleness and cache status, and attribution to NOAA SWPC.
Example use cases
Aurora chasing in Alaska
“I'm in Fairbanks right now at about 64.8 latitude, -147.7 longitude — what's the OVATION aurora probability and is it dark enough to see the northern lights tonight?”
Northern lights trip planning alert
“Can you check the aurora nowcast for Tromsø Norway, roughly latitude 69.65, longitude 18.95, and tell me the probability and Kp index so I know whether to head out?”
Automated aurora monitoring for a remote cabin
“Check the current aurora visibility probability at latitude 67.5, longitude 26.0 in Finnish Lapland and let me know the likelihood rating and whether the sky is dark enough for viewing.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/space/aurora?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, point-specific aurora visibility probability derived from the NOAA SWPC OVATION model, especially for agentic workflows that need a structured JSON response with Kp index, sun altitude, and a dark-sky check at a specific lat/lon. Prefer it over general space weather sites when you need machine-readable nowcast data for automated aurora monitoring, travel planning agents, or notification systems.
Side effects
- Coordinates out of range (-90 to 90 lat, -180 to 180 lon) return validation error
- Stale data if NOAA SWPC feed is delayed (stale: true in response)
- Cached response returned within cache_seconds window (600s)
- Sun above -12° means dark_enough=false even if aurora probability is high
- No cloud cover or light pollution modelling — probability assumes ideal dark clear sky
