DFlight API: common questions
Is DFlight API free to use?
Yes — DFlight API is a free weather API. Free tier: Free — limits not published. Whether the free tier allows commercial use is unclear — check the provider docs.
Does DFlight API need an API key?
No — DFlight API needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).
Can I call DFlight API from the browser?
Yes — DFlight API returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.
Is DFlight API up right now?
DFlight API is catalogued but not yet on our probe schedule, so we don't publish a live status for it. Check the provider's own status page or docs for its current state.
