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.
Does the FlyItalyADSB API have per-second or burst limits?
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 → Can I use FlyItalyADSB data in a product I sell, and what does the licence ask?
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 → Does FlyItalyADSB cover my country, for example the UK, Spain, the US, Canada or Germany?
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 → How reliable is the FlyItalyADSB API, and is there an SLA?
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 → Does a FlyItalyADSB radius request return every aircraft, or only 25?
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.
