How this service works
Use when you need airport delays, FAA ground stops or the airport status of a US airport right now, such as departure delays or closures. Do not use for the status of a flight number, airports outside the US or historical delays. Returns JSON with current US airport delays from the FAA: ground stops, ground delay programs with average and maximum delay, arrival and departure delays and closures, for all airports or one for 0.007 USDC per call. Typical response time 1500 ms (p95). Category: Data.
Output
A JSON object containing the timestamp of last update, the queried airport code (or null for all airports), total number of active delay events, and arrays of ground stops (with airport and reason), ground delay programs (with average and maximum delay in minutes), arrival/departure delays, and closures (with reason, start time, and reopen time). Also includes an FAA attribution string and a suggested next call hint.
Example use cases
Pre-departure delay check for travelers
“Before I head to the airport, can you check if there are any current FAA ground stops or arrival delays at JFK right now?”
Airline ops dashboard ground stop monitoring
“Pull up the current FAA delay status for all US airports so I can see which ones have active ground stops or ground delay programs.”
Connecting flight risk assessment
“I have a connection through ORD in two hours — is there a ground stop or any departure delays at Chicago O'Hare right now according to the FAA?”
Technical details
Endpoint
POSThttps://x402-gateway.blackwoodstate8.workers.dev/v1/airport-delays?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time FAA-sourced US airport operational status — ground stops, ground delay programs, or arrival/departure delays — for one specific US airport or all US airports at once. Do not use for tracking a specific flight number's status, for airports outside the US, or for historical delay data.
Side effects
- Invalid or non-US airport code returns an error or empty result — endpoint only supports US airports
- No delays present returns a valid response with empty arrays and total=0
- Truncated or stale FAA data if FAA upstream is slow — updatedAt timestamp may be older than expected
- Non-existent airport code (e.g. typo like 'SFX') may return empty or error response
- Payment failure (insufficient USDC) results in 402 response before data is returned
