# AgentGate Route Distance API

> AgentGate Route Distance API is a paid API for AI agents from agentgate-x402.netlify.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns the great-circle distance and estimated flight time between two airports identified by IATA or ICAO codes

## Facts

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 agentgate-route-distance-api-0a2d0f4a
```

Example prompt: What's the great-circle distance and estimated flight time between JFK and LHR?

## When to prefer this

Use this endpoint when you need quick, machine-payable airport-to-airport route distances and flight time estimates without setting up an account or API key. Ideal for AI agents that need on-demand aviation route data at $0.002 per call via USDC on Base. Prefer this over full flight search APIs when you only need distance/duration data, not schedules or pricing.

## Known failure modes

- Invalid or unrecognized IATA/ICAO code returns an error
- Missing required 'from' or 'to' query parameters returns a 400 error
- Payment not included or insufficient USDC balance triggers a 402 Payment Required response
- Network timeout if the endpoint is temporarily unavailable

## How this service works

Machine-payable micro-APIs: web content extraction, airport data, route distances and DNS intelligence. No accounts, no API keys — AI agents pay $0.002–$0.005 per request in USDC on Base via the x402 protocol.

## Output

A JSON object containing the origin and destination IATA codes, distance in kilometers, miles, and nautical miles, and estimated flight time as a decimal hours value and a formatted string (e.g. '7h 06m').
