FAA NAS Operational Disruption Causal-Chain Gauge (US Air Hub)
x402
FAA NAS Operational Disruption Causal-Chain Gauge (US Air Hub) is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).
Returns a real-time causal-chain snapshot of aviation disruptions at a US hub airport, linking upstream weather (METAR) to current FAA ground stops/delays and downstream network propagation for air-cargo and logistics intelligence.

How this service works
[3-LEG] Aviation ground-stop chain, one airport (?entity=ewr): leading aviation weather - METAR ceiling, visibility, convection and gusts -> current FAA NAS ground stops and delay programs -> realized realized delay (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: FAA NAS Status, NWS METAR. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
A structured JSON object containing: the airport entity key, a causal-chain narrative across upstream weather legs (METAR cloud ceiling, visibility, convection, gusts), current FAA NAS ground stop/GDP/AFP/delay/closure status legs, realized delay metrics, downstream hub propagation and air-cargo freight exposure flags, a reason_category (WEATHER/VOLUME/EQUIPMENT/RUNWAY), sequential confidence scoring ('lights on' causal chain), freshness/provenance metadata with data age and lineage, a grade disclosure (screening-level), and an Ed25519-signed cryptographic citation for zero-trust verification.
Example use cases
Air cargo delay risk screening
“Check the current FAA NAS status for ORD — is there an active ground stop or GDP, what's the METAR weather showing for ceiling and visibility, and is there downstream cargo network exposure I should flag for our Chicago freight shipments?”
Real-time logistics disruption alert
“I need the live disruption causal-chain for JFK right now: upstream weather conditions, any active FAA delay programs or airport closures, and what the reason category is — WEATHER, VOLUME, EQUIPMENT, or RUNWAY?”
Hub propagation risk for freight forwarder
“What's happening at SFO in the FAA NAS right now? Walk me through the causal chain from weather through ground operations to any realized delays, and tell me if our downstream hub air cargo exposure is lighting up.”

Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/nas-regionWhen to prefer
Use this endpoint when you need a real-time, single-airport, causal-chain view linking aviation weather (METAR) directly to active FAA NAS ground stop/delay programs and downstream air-cargo network exposure at US hub airports. Prefer this over general flight status APIs when the goal is logistics risk screening, freight exposure assessment, or understanding the weather-to-operations causal sequence rather than individual flight booking or tracking. Best suited for air cargo agents, logistics planners, and supply chain monitors who need verifiable, source-cited operational intelligence at screening level.
Side effects
- Invalid or unknown airport code returns error or empty entity
- FAA or AviationWeather source temporarily unavailable causing stale data (indicated by freshness=stale in provenance)
- Data age may be non-zero if official sources have not updated recently
- Endpoint is screening-level only — not decision-grade for operational safety or flight dispatch
- Payment of 0.1 USDC required per call; unpaid requests return 402 Payment Required
- Downstream hub propagation data may lag behind primary airport status
