# Airports Reference – Airport Timezone Offset

> Airports Reference – Airport Timezone Offset is a paid API for AI agents from airports-reference.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Returns a nominal solar UTC offset for an airport and reports that actual timezone data is not available in the dataset.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability airports-reference-airport-timezone-offset-4d95c580
```

Example prompt: What is the nominal solar UTC offset for Sydney Airport (SYD)? I just need the timezone offset information and whether the dataset has actual timezone data for it.

## When to prefer this

Use this endpoint when you only need a rough solar-longitude-based UTC offset for an airport and do not require authoritative DST-aware timezone data. It is useful for quick sanity checks on approximate local time at an airport when full timezone accuracy is not critical. For precise, DST-correct timezone lookups use a dedicated timezone database instead.

## Known failure modes

- Unknown airport code or name returns null airport object and a not-found verdict
- Ambiguous name with multiple matches may return degraded results or require a more specific query
- Solar offset is a rough longitude-based estimate and will not reflect DST or political timezone boundaries
- If q parameter is missing the API will return an error

## How this service works

Time zone offset of an airport: reports whether the dataset has one (it does not) and gives a nominal solar offset.

## Output

Returns an object with the airport's identity details (IATA, ICAO, name, lat/lon, country, region, elevation, municipality), a nominal solar offset in hours (computed from longitude), a verdict and summary indicating that actual timezone data is absent from the dataset, a list of reasons, a disclaimer, degraded-data flag, and attribution. The utcOffsetHours and timezone fields will typically be null.
