## 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 api-strale-io-4ae833e4
```

Example prompt: Can you check the current status of flight LH400 — is it on time, and what gate is it departing from?

## When to prefer this

Use this endpoint when you need real-time or near-real-time flight status for a specific flight number, including departure/arrival times, delay information, and gate data. Prefer this over general travel search APIs when you already have the flight number and need operational status details.

## Known failure modes

- Invalid or malformed flight number returns an error
- Flight number not found in database returns no results
- Missing or invalid AVIATIONSTACK_API_KEY results in authentication error
- Network timeout from upstream aviation data provider
- Historical or future flights beyond data window may return incomplete data

## How this service works

## Output

Returns departure and arrival times, any delay information, gate assignments, and overall flight status for the queried flight number.
