How this service works
Active in-flight weather hazard advisories (SIGMETs and AIRMETs) from the NOAA Aviation Weather Center. Returns current advisories over a lookback window (1-24h), optionally filtered by hazard (CONVECTIVE, TURB turbulence, ICE icing, IFR, MTN OBSCN mountain obscuration, ASH volcanic ash). Each advisory carries the issuing office, type (SIGMET/AIRMET/OUTLOOK), hazard, severity, valid-from/to times, affected altitude band (feet MSL), movement (direction/speed), and the raw text bulletin. Keyless, public-domain (NOAA). The active-hazard layer aviation agents need — distinct from aviation.metar (station conditions) and aviation.taf (forecasts). Not for navigation.
Output
Returns a JSON array of active SIGMET advisories, each with raw text, hazard type, ICAO region ID, validity start/end times, altitude bounds (low and high in feet), movement direction (degrees) and speed (knots), and severity. Also includes total count and NOAA source metadata.
Example use cases
Example prompt
“Pull the latest SIGMETs from the past 6 hours, up to 30 advisories, and filter for just convective hazards — I need to know what's active right now for flight planning.”
Technical details
Endpoint
GEThttps://2s.io/api/aviation/sigmetWhen to prefer
Use this endpoint when an AI agent needs real-time, ground-truth SIGMET data sourced directly from NOAA for aviation safety, flight planning, or meteorological monitoring. Prefer over manual weather lookups or general weather APIs that don't surface structured SIGMET data with altitude, movement, and hazard classification.
Side effects
- Invalid hazard filter string returns empty or error response
- hours parameter out of 1–24 range may be rejected or clamped
- limit parameter out of 1–50 range may be rejected
- No active SIGMETs matching filter returns empty items array
- NOAA upstream outage causes error or stale data
- Payment failure (402) if USDC balance insufficient
