Feed Data to OpenSky
Want to become a feeder and support thousands of academic researchers around the world?
It's easy! Choose the setup that fits your hardware below.
Feeding boosts your API access.
You get 8,000 API credits per day whenever at least one of your
receivers has been online for more than 30% of the current month so far.
Uptime is recalculated daily, so today's feeding starts counting from tomorrow.
How and when the boost kicks in
“Active feeder” is not a role or a setting. There is
nothing to request and no support ticket to raise. It is worked out automatically from your
receiver uptime. As long as at least one receiver has been online for more than
30% of the current month, you qualify. The number of receivers doesn't matter;
uptime does.
Two things then have to happen before your credits actually change, which is why the boost
isn't instant:
We re-check who's feeding on a schedule. Once your uptime crosses 30%
there is a short delay before the next recalculation picks you up as an active feeder.
Your limit updates after you've made a few more calls. Your allowance
lives in a separate “bucket” for each endpoint
(/states/all, /flights/*, /tracks/all). Once you
qualify, a bucket is bumped to 8,000 the next time it is re-checked, roughly
every 50 requests to that endpoint. So keep making requests: each endpoint
upgrades on its own once you've hit it enough times. Until then,
X-Rate-Limit-Remaining can still show the old 4,000 limit.
No action is needed; it switches over by itself. Your daily credits refill as a single
lump when your window resets, not gradually through the day.
ADS-B Feeding
Raspberry Pi
The easiest way to get started. Whether you're new to feeding or already feeding other
networks, a Raspberry Pi with an RTL-SDR dongle is all you need. We recommend using
adsb.im — a ready-made multi-feeder image
that gets you sharing data with OpenSky and other networks in minutes, with no command-line
experience required.
