## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Live Flight Tracker (OpenSky)

**Export real-time aircraft positions** worldwide or inside a geographic bounding box — callsign, latitude/longitude, altitude, speed, heading, vertical rate, squawk and origin country. Powered by the **OpenSky Network** public REST API: **no API key required** for anonymous access.

### What you get (one aircraft per result)

| Field | Description |
|---|---|
| `icao24` | Unique transponder address (hex) |
| `callsign` | Flight callsign (e.g. `DLH4AB`) |
| `originCountry` | Country the aircraft is registered to |
| `latitude`, `longitude` | Current position (decimal degrees) |
| `baroAltitudeM`, `geoAltitudeM` | Barometric / geometric altitude (m) |
| `velocityMs`, `headingDeg`, `verticalRateMs` | Speed, track, climb/descent |
| `onGround` | On the ground vs airborne |
| `squawk`, `spi`, `positionSource` | Transponder code + flags |
| `timePosition`, `lastContact`, `snapshotTime` | ISO timestamps |
| `trackUrl` | Link to the aircraft profile on OpenSky |

### Example input

```json
{
  "lamin": "45.8389",
  "lomin": "5.9962",
  "lamax": "47.8229",
  "lomax": "10.5226",
  "onlyAirborne": true,
  "maxItems": 5000
}
```

### Example output (1 row)

```json
{
  "icao24": "39de57",
  "callsign": "TVF72VT",
  "originCountry": "France",
  "latitude": 47.219,
  "longitude": 8.1556,
  "baroAltitudeM": 11887.2,
  "velocityMs": 231.56,
  "headingDeg": 111.78,
  "onGround": false,
  "snapshotTime": "2026-06-21T12:47:23.000Z"
}
```

### Use cases

- **Aviation / logistics analytics** — airspace and airport-traffic snapshots.
- **Journalists & OSINT** — track specific aircraft by ICAO24.
- **Travel & mapping apps** — live overlay data without running your own receiver.
- **Research** — noise studies, route analysis, dataset building.

### Honest notes

- Anonymous OpenSky access is **rate-limited** and updates roughly every 10 seconds — this actor takes a **snapshot per run** (global or bounding-box), not a per-second feed.
- For higher limits, supply your free **OpenSky account** username/password in the input; the actor uses them automatically.
- Coverage depends on OpenSky's volunteer receiver network (excellent over Europe/N. America, sparser elsewhere).

### How it works

Calls `opensky-network.org/api/states/all` with an optional bounding box and/or ICAO24 filter, maps each state vector to a clean record, and pushes one aircraft per dataset item (pay-per-result).

# Actor input Schema

## `lamin` (type: `string`):

Southern edge of the area to scan (decimal degrees, e.g. 45.8389). Leave all four bounding-box fields empty to scan the whole world.

## `lomin` (type: `string`):

Western edge (decimal degrees, e.g. 5.9962).

## `lamax` (type: `string`):

Northern edge (decimal degrees, e.g. 47.8229).

## `lomax` (type: `string`):

Eastern edge (decimal degrees, e.g. 10.5226).

## `icao24` (type: `array`):

Optional list of ICAO24 transponder addresses (lowercase hex, e.g. 39de57) to track only those aircraft.

## `onlyAirborne` (type: `boolean`):

Exclude aircraft currently on the ground.

## `requirePosition` (type: `boolean`):

Skip aircraft with no latitude/longitude in this snapshot.

## `maxItems` (type: `integer`):

Maximum number of aircraft to output from this snapshot.

## `openSkyUsername` (type: `string`):

Optional OpenSky Network account username for higher rate limits. Leave empty to use anonymous access.

## `openSkyPassword` (type: `string`):

Optional OpenSky Network account password (used with the username above).

## Actor input object example

```json
{
  "icao24": [],
  "onlyAirborne": false,
  "requirePosition": true,
  "maxItems": 10000
}
```

# API

});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("foo121/flight-tracker-opensky").call(input);

// Fetch and print Actor results from the run's dataset (if any)

## CLI example

```bash
echo '{}' |
apify call foo121/flight-tracker-opensky --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,foo121/flight-tracker-opensky"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
