Real-time airport delay data from FlightAware via pay-per-request micropayment — $0.10 per call, no API keys.
What it does
This endpoint returns all current airport delays across the system, sourced from FlightAware's AeroAPI. It is part of StableTravel, a pay-per-request travel API suite that wraps Amadeus, FlightAware, and Google Flights data behind MPP/x402 micropayment protocols. No API keys, OAuth tokens, or subscriptions are required — payment via USDC on Tempo (chainId 4217) serves as authentication.
A single GET request to `/api/flightaware/airports/delays` returns an array of delay objects, each containing the airport name, airport code, a color-coded severity indicator, and an array of delay reasons with category, severity color, delay duration in seconds, and affected flight count. The endpoint costs $0.10 per call (100,000 base units of pathUSD on Tempo L2, 6 decimals). The response schema is fully documented in the OpenAPI spec.
The endpoint is confirmed live via a 402 MPP challenge. It accepts GET requests with no required query parameters. For per-airport delay data, use the sibling endpoint `/api/flightaware/airports/{id}/delays` at $0.02 per call. Related endpoints include airport weather observations (METAR), forecasts (TAF), and disruption counts by airline or airport.
Capabilities
Use cases
- —Monitor system-wide airport delays for travel planning agents
- —Build real-time airport status dashboards
- —Alert travelers about delays before departure
- —Feed delay data into itinerary optimization workflows
- —Aggregate delay trends for airline operations analysis
Fit
Best for
- —AI travel agents that need real-time delay awareness before booking
- —Operations dashboards monitoring US and global airport delays
- —Autonomous agents that pay per call without managing API credentials
Not for
- —Historical delay analytics over long time periods (use history endpoints instead)
- —Per-flight delay tracking (use /flightaware/flights/{ident} instead)
- —Free or bulk data access without per-request payment
