# Nearest Airports by Coordinate

> Nearest Airports by Coordinate is a paid API for AI agents from mcpfax-utility.bowling-anthony.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Given a geographic coordinate (latitude/longitude), returns the nearest airports with their IATA and ICAO codes, sorted by distance.

## Facts

- Endpoint: GET https://mcpfax-utility.bowling-anthony.workers.dev/v1/airports/nearest
- Price: $0.008/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nearest-airports-by-coordinate-89474013
```

Example prompt: What are the three nearest airports to coordinates 48.8566, 2.3522, and include their IATA and ICAO codes?

## When to prefer this

Choose this endpoint when you need to resolve a geographic coordinate to the nearest airport identifiers (IATA/ICAO) — ideal for travel, logistics, flight search pre-processing, or any workflow that starts with a GPS position and needs aviation context. Prefer this over a general geocoding API when airport-specific codes and distance ranking are required.

## Known failure modes

- Invalid or out-of-range coordinates return a validation error
- Coordinates in ocean or remote areas with no nearby airports may return an empty list or very distant results
- Missing required latitude or longitude fields return a 400-level error
- Payment not included or insufficient USDC results in a 402 Payment Required response

## How this service works

Nearest airports — Coordinates → nearest airports (IATA/ICAO) by distance.

## Output

Returns a ranked list of nearby airports, each including the airport name, IATA code, ICAO code, geographic coordinates, and distance from the queried point, sorted nearest-first.
