It can be used in a product you sell on every plan, Free included, with one attribution line; the whole world in one request costs €49 a month (Pro). This page has the facts a developer compares when choosing a flight data API, the rules in short, and the right pattern for each kind of product. ## Key facts for comparing flight data APIs - **What it is:** A REST API with live positions of aircraft worldwide, from ADS-B and multilateration (MLAT), collected by a network of about 3,192 receivers. JSON, base `https://api.flyitalyadsb.com/v2`, key in the `X-Api-Key` header. - **Coverage:** Worldwide: ~11,000 aircraft with a position at the measurement of 26 October 2026, 20:24 UTC. Receivers: United States 36%, Germany 15%, UK and Ireland 11%, Rest of Europe 16%. - **Data per aircraft:** readsb’s aircraft.json format: ICAO hex, position, barometric and geometric altitude, speed, track, vertical rate, squawk (~85%), callsign (~98%), registration (~99%), ICAO type (~99%), category, military/PIA/LADD flags (`dbFlags`) and position source (`type`: ADS-B or MLAT; 88% from ADS-B). No routes or schedules. - **Filtering:** None: military, PIA and LADD aircraft included, also those seen only through our multilateration. - **Freshness:** The picture refreshes every half second; median position age 0.32 s (90th percentile 8.1 s). - **Plans and prices:** Free, Starter €9, Pro €49, Fleet €149 a month, before tax. Limits per plan in the table below; the whole world in one request with Pro and Fleet. - **Over the limits:** An error (429, or 403 for the radius), never extra costs: refused requests aren’t counted or billed. - **Commercial use:** Yes, on every plan, Free included, in apps and devices you sell too. [The rules](https://flyitalyadsb.com/data/products/using-the-data.md). - **Licence:** Data under CC BY-SA 4.0: one attribution line (“Flight data: FlyItalyADSB (flyitalyadsb.com), CC BY-SA 4.0”). Share-alike covers the data and datasets built from ours, not your product’s code or design. - **Keys:** One per product, free, with an email address and no card: [get it here](https://flyitalyadsb.com/data/api/#api-key). Moving to a paid plan keeps the same key. - **History:** Each aircraft’s daily track, every day since 17 August 2026 (today included, up to about 10 minutes ago), plus periods in 2022–2024 with gaps; and which aircraft flew over a place in a time window. [History](https://flyitalyadsb.com/data/api/docs/history.md). - **Alerts:** Events by area (emergencies 7500/7600/7700, military and other notable aircraft, up to 7 days) on every plan; signed webhooks on paid plans. [Alerts](https://flyitalyadsb.com/data/api/docs/alerts.md). - **Formats and tools:** [OpenAPI 3.1](https://flyitalyadsb.com/openapi.json), [ADS-B Exchange v2–compatible paths](https://flyitalyadsb.com/data/api/docs/adsbx-v2.md), an [MCP server](https://flyitalyadsb.com/data/mcp.md) for AI assistants, examples on [GitHub](https://github.com/flyitalyadsb/adsb-api). - **Reliability:** Best effort, no SLA. Public [status page](https://flyitalyadsb.com/status/) with history and email alerts. - **Who runs it:** A network started in Italy in 2020; servers and billing by Nesso Labs S.r.l. (Brescia, Italy). [Contact](https://flyitalyadsb.com/contact/). - **In production:** [FlyScout](#built-on-it), an app that finds unusual flights worldwide, on the Pro plan. - **Comparison:** Limits, terms of use and requirements of the other open ADS-B APIs, side by side: [the comparison](https://flyitalyadsb.com/data/comparison.md). ## The rules, in short - In a product you sell: yes, on every plan. - One key per product, not per device. - Your own server with a cache: yes, and it’s the lightest option. - One attribution line; share-alike covers the data, not your product. - Over the limits: an error, never extra costs. No SLA. - Position, altitude, speed, registration and type; no routes. The rules in full, as questions and answers: https://flyitalyadsb.com/data/products/using-the-data.md ## Which plan for which product | Use | Requests per minute | Requests per month | Smallest plan | | --- | --- | --- | --- | | 1 device, every 30 s, 15 km around it | 2 | 86,400 | Free | | 3 devices, every 30 s, 15 km | 6 | 259,200 | Free | | 10 devices, every 30 s, 50 km | 20 | 864,000 | Starter | | 90 devices, every 30 s, 15 km | 180 | 7,776,000 | Pro | | Your server fetches the whole world every 30 s, for any number of users | 2 | 86,400 | Pro | Plans: Free €0 (30 requests/minute, 300,000/month, 500 km radius, 7 days of flight history), Starter €9 (60 requests/minute, 1,000,000/month, 1,000 km radius, 14 days of flight history), Pro €49 (300 requests/minute, 10,000,000/month, whole world, 30 days of flight history), Fleet €149 (300 requests/minute, 10,000,000/month, whole world, 90 days of flight history, up to 25 watched aircraft with takeoff and landing webhooks). Prices per month, before tax. ## The right pattern for each kind of product - **Displays and devices** (desk displays, e-paper frames, LED panels, ESP32, Raspberry Pi): for a few units each device can ask for its own area; from a few dozen units, one server of yours fetches once and serves all devices, so usage does not grow with units sold and the key never ships in firmware. Guide: https://flyitalyadsb.com/data/products/displays-and-devices.md - **Mobile and web apps** (spotting, unusual flights, alerts, maps): the key stays on your server, which keeps one cache refreshed every 30 s; the app asks your server. Usage depends on the refresh, not on users. Guide: https://flyitalyadsb.com/data/products/apps.md - **Drones and light aviation** (planning, traffic awareness): what shows up at low altitude and what does not; never a certified collision-avoidance tool. Guide: https://flyitalyadsb.com/data/products/drones.md ## Built on it FlyScout (Apptractor, https://www.flyscout.app/): Finds unusual flights worldwide, such as go-arounds, holds, emergencies and tankers flying racetracks, and replays them on a map. FlyScout’s server reads the whole world from our API and derives the events; the app only talks to that server. “Really happy I switched to your service.” (Stan, Apptractor).
