{"jsonrpc":"2.0","id":1,"method":"tools/list"}route_ontime — Monthly on-time performance for one US domestic flight route (origin airport -> destination airport), from BTS TranStats Reporting Carrier On-Time Performance. Returns, per month (and per carrier if more than one serves the route): flights, completed flights, on-time arrivals and on-time %, average arrival delay in minutes, cancellations, diversions, and delay minutes broken down by cause (carrier, weather, NAS/air-traffic-control, security, late aircraft). Pass carrier (2-letter code like "DL", or a common name like "Delta") to scope to one airline; omit it to see every carrier that flew the route. months caps how many of the most recently loaded months to return (default 12). Covers the most recent months loaded (see data_as_of and the earliest/latest fields), not full history. Unknown origin/destination airport codes are refused with a clear error, never an empty success.carrier_ontime — Monthly on-time performance for one airline, aggregated across all its routes (or just the routes touching one airport), from BTS TranStats Reporting Carrier On-Time Performance. Pass carrier as a 2-letter code ("WN") or common name ("Southwest"). Pass airport to scope to flights where that airport is the origin or destination. Returns the same per-month shape as route_ontime (flights, on-time %, average arrival delay, cancellations, diversions, delay minutes by cause). months caps how many of the most recently loaded months to return (default 12). Unknown carrier codes are refused with a clear error, never an empty success.bts_airport_delays — Delay-cause breakdown at one US airport (as the ARRIVAL airport), by carrier, from BTS TranStats on-time data: arriving flights, how many arrived 15+ minutes late, cancellations, diversions, and delay minutes attributed to carrier, weather, NAS (air-traffic-control/system), security, and late-aircraft causes. Pass year and/or month to scope to a specific period; omit both to get every loaded month, most recent first. Rows beyond `limit` are reported via truncated/total_matching rather than silently dropped -- narrow with year/month or page with limit/offset to see the rest. Unknown airport codes are refused with a clear error, never an empty success.delay_causes — Delay-cause rows for a given year, optionally scoped to one carrier and/or one (arrival) airport, from BTS TranStats on-time data. Same fields as bts_airport_delays (arriving flights, 15+ minute-late arrivals, cancellations, diversions, delay minutes by cause) but organized by year first rather than by airport first -- use this to scan a whole year across carriers/airports, or to compare one carrier's delay profile across the airports it serves. Rows beyond `limit` are reported via truncated/total_matching rather than silently dropped -- narrow with carrier/airport or page with limit/offset to see the rest. Unknown carrier or airport codes are refused with a clear error, never an empty success.list_coverage — What this pack actually has loaded right now: the earliest and latest BTS month covered, how many months, and when it was last loaded. Call this before route_ontime/carrier_ontime/bts_airport_delays/delay_causes if you are not sure a given month or year is covered.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
