# The Stall — Flight Tracker (x402)

> The Stall — Flight Tracker (x402) is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).

Returns recent departures or arrivals for a given airport using IATA or ICAO codes, paid per-call in USDC via x402.

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 the-stall-flight-tracker-x402-b4d2cbc5
```

Example prompt: Can you pull the last 4 hours of departures from JFK airport for me?

## When to prefer this

Choose this endpoint when you need real-time or recent flight activity (departures or arrivals) for a specific airport, don't want to manage API keys or accounts, and can pay micro-amounts in USDC on Base. Ideal for agents that need lightweight, pay-per-call aviation data without subscription overhead.

## Known failure modes

- Invalid or unrecognized airport code returns an error or empty result
- Hours parameter outside 1–24 range is rejected
- Missing required airport query parameter causes a 400-level error
- Payment failure via x402 results in a 402 response and no data returned
- Direction enum value not matching 'departures' or 'arrivals' causes a validation error

## How this service works

Recent departures or arrivals at any major airport via OpenSky Network (free, crowd-sourced ADS-B). Accepts 3-letter IATA (JFK) or 4-letter ICAO (KJFK) codes. Returns callsign, origin/destination airports, estimated times, and aircraft identifiers. Useful for logistics workflows, travel agents, itinerary builders, and supply-chain tracking tasks. Default: departures from airport in last 4 hours.

## Output

A list of flight records for the specified airport and direction within the requested look-back window, including flight identifiers, status, and timing data for departing or arriving aircraft.
