# Nearby Airports Lookup

> Nearby Airports Lookup is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-02).

Returns a list of airports near a given latitude/longitude coordinate, with optional filtering by airport type and result limit.

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 nearby-airports-lookup-087b04cf
```

Example prompt: Find me airports near coordinates 40.7128 latitude, -74.0060 longitude — show me up to 10 results and include all airport sizes.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call geospatial lookup for airports near a coordinate pair, especially in agent workflows where you don't want to maintain a full aviation database. Prefer this over scraping flight sites or querying large aviation APIs when you just need proximity-based airport discovery with optional type filtering.

## Known failure modes

- Missing required lat or lon parameters returns an error
- Invalid coordinate format may cause a 400 or empty result
- Result count exceeds max limit of 50 — capped silently
- Unknown airport type value may return empty results
- Payment not completed (402) if x402 protocol not followed

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing an array of airport records near the queried coordinates, a count of results, and an attribution/license line for the data source.
