- 1 credit per completed run (1¢ with pay as you go); failed runs are free.
- Method
faa.gov/get_airport_delays- Returns
- airport name, code, whether a delay is active, events (type, reason, delays, trend, times)
Use it from your agent
Give your agent this line. It reads SKILL.md, gets a Fous API key and connects the Fous MCP server. Its run then takes the method faa.gov/get_airport_delays with the inputs above.
Ask your agent
- Is there any ground delay at LAX right now?
- Are flights into Denver being held up today?
- What's the current delay status for JFK?
- Any FAA closures or delays reported at Chicago O'Hare this afternoon?
- Check whether Seattle-Tacoma has an active delay program and the reason given.
