REST API · MCP server · live map
FlyItalyADSB is a global community network, born in Italy in 2020, with about 3,200 receivers: they send us their data directly, ADS-B and our own multilateration, open and unfiltered. You can use the API in a product you sell on every plan, Free included.
The free key arrives by email in a minute: no card, no receiver needed.
For builders
Pro plan
FlyItalyADSB’s Pro plan, €49 a month + VAT, returns the whole world in one request: every aircraft the network sees, about 11,000 with a position. Polling it every 10 to 30 seconds is 86,400 to 259,200 requests a month, well inside Pro’s 10 million, with commercial use included, in a product you sell too, and no overage: over a limit you get an error, never an extra charge.
Apps: patterns and code →Any plan
Customers’ desk and wall displays run on an ESP32 or a Raspberry Pi. Keep the key on your own server and let every display ask it: one request every 30 seconds is 86,400 requests a month, however many displays you sell.
Guide: displays and devices →From Starter, €9 a month
/v2/events returns the emergencies and notable aircraft in an area (squawk 7500, 7600 and 7700, military and other rare aircraft): the last 24 hours on Starter, 7 days on Pro and Fleet. With area alerts they reach your server as signed webhooks: 1 area on Starter, 5 on Pro and Fleet. Fleet adds takeoff and landing alerts for up to 25 watched aircraft.
Alerts and webhooks: docs →Before you build
These come by email from people about to put the data in a product. The short answers are here, the full ones in the docs.
The plans count requests per minute and per month, not per second: Free 30 a minute and 300,000 a month (and at most 100 a minute per IP), Starter 60 and 1,000,000, Pro and Fleet 300 and 10 million. The per-minute allowance refills continuously; a flood guard per IP, well above Pro’s rate, only stops abnormal bursts. Over a limit you get a 429 with Retry-After (a 403 for a radius larger than the plan’s), never a charge, and the refused request is not counted. Changes to plans and limits are announced by email at least 30 days ahead on paid plans and 7 on Free.
Limits and errors →Yes, on every plan, Free included: apps, devices, websites and paid services. The data is CC BY-SA 4.0, so one line where your users see the data is enough: “Flight data: FlyItalyADSB (flyitalyadsb.com), CC BY-SA 4.0”. Share-alike covers the data and the datasets, feeds or APIs built from it, not your product’s code, artwork or design. You can keep what you receive and what you derive from it, tracks and statistics included, even after you stop using the API, as long as the credit stays; a social media post with a map or a chart made from our data carries the same line. Reselling the data as an API or feed for other people’s products needs a written agreement.
Commercial use →Coverage follows the receivers. Of those with a declared position on 28 October 2026, 36% were in the United States, 15% in Germany, 11% in the UK and Ireland, 5% in Canada and 16% in the rest of Europe, Spain included. Before you pick a plan, check your area on the coverage page: the aircraft seen there in the last 24 hours, the positions right now by source and the receivers nearby, also as JSON without a key.
Check the coverage →It is best effort, and no plan includes an SLA: one can only be agreed in writing. Nesso Labs S.r.l. operates the API and its servers, and the public status page shows each component’s measured uptime and every incident, with email alerts. You can keep a cache on your own server, and a second source to fall back on when our API does not answer.
Service status →Every aircraft the network sees in the area: a radius request has no cap on the number of aircraft, and on Pro and Fleet one request covers the whole world: about 11,000 aircraft with a position at the measurement of 26 October 2026, 20:24 UTC. The 25 in the plans is something else: how many aircraft a Fleet account can watch for takeoff and landing alerts.

With a Raspberry Pi, an RTL-SDR dongle and an antenna (about €55–110) you send your receiver’s data to the network. In return you get the API with Pro’s limits and features, free, and Lightcone, which shows the aircraft that passed near you and you did not receive, and how you compare with nearby receivers.
