SkyBiometry vs TensorFeed: common questions

Which is more reliable, SkyBiometry or TensorFeed?

Only TensorFeed is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do SkyBiometry and TensorFeed need an API key?

TensorFeed needs no key, while SkyBiometry requires a free API key. If you want to start calling without signup, reach for TensorFeed first.

Can I call SkyBiometry and TensorFeed from the browser?

Only TensorFeed is browser-friendly — it returns CORS headers over HTTPS. SkyBiometry needs a server-side call or proxy, so factor that into which one fits a front-end project.

Are SkyBiometry and TensorFeed free for commercial use?

SkyBiometry has unclear commercial terms, and TensorFeed has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
