AviationAPIs TAF Decoder
x402
AviationAPIs TAF Decoder is a paid API for AI agents from aviationapis.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Parses and decodes a raw Terminal Aerodrome Forecast (TAF) string into structured JSON with forecast periods, wind, visibility, cloud layers, and validity times.

How this service works
Pay-per-call aviation data APIs for AI agents, settled in USDC via the x402 protocol.
Output
A structured JSON object containing the station ICAO code, issuance time, validity window, amendment flag, and an array of forecast periods each with type (INITIAL, FM, TEMPO, BECMG, PROB), from/to times, wind direction and speed in knots, gust speed, visibility in statute miles, CAVOK flag, cloud layers (cover type and base altitude in feet), weather phenomena, and probability.
Example use cases
Parse TAF for flight planning
“I've got this raw TAF string for KJFK and I need to build out a flight plan — can you decode it and pull out each forecast period with the wind direction, speed, and visibility so I can check if conditions are suitable for my departure window? TAF KJFK 081755Z 0818/0924 18015KT 6SM -RA BKN040 FM082200 22020G35KT 4SM TSRA OVC025 TEMPO 0900/0904 1SM +TSRA OVC010”
Extract cloud layers from TAF
“Can you parse this TAF for EGLL and just give me the cloud layers and ceiling heights for each forecast period? I want to know when conditions drop below 1500 feet so I can flag any IFR risk. TAF EGLL 101155Z 1012/1118 24015KT 9999 FEW018 BKN030 BECMG 1014/1016 18008KT SCT010 OVC015 TEMPO 1018/1022 3000 -SHRA BKN008”
Interpret ATIS TAF string
“We just pulled this TAF off the ATIS broadcast at KDFW and the pilots are asking what it means — can you decode it into structured forecast periods so I can quickly walk through the wind, visibility, and any weather phenomena expected over the next 24 hours? TAF KDFW 150530Z 1506/1612 35010KT P6SM SKC FM151400 18012KT P6SM FEW025 FM152000 20018G28KT 5SM TSRA OVC030”
Technical details
Endpoint
POSThttps://aviationapis.com/decode-tafWhen to prefer
Use this endpoint when you have a raw TAF text string (from an ATIS, METAR source, or user input) and need it decomposed into machine-readable forecast periods for downstream processing, flight planning logic, or display. Prefer this over manual regex parsing or general-purpose LLM interpretation when structured, field-level accuracy is required for wind, visibility, and cloud data.
Side effects
- Malformed or empty TAF string returns a parsing error
- Unsupported TAF format or non-standard encoding may produce incomplete period extraction
- Missing required 'raw' field returns a 400-level error
- Payment not settled via x402 protocol returns a 402 Payment Required response
