OOPSpam vs ipify: common questions

Which is more reliable, OOPSpam or ipify?

Only ipify 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 OOPSpam and ipify need an API key?

Neither needs a paid key — OOPSpam is callable with no signup, and ipify is callable with no signup. Both are quick to prototype with; rate limits still apply.

Can I call OOPSpam and ipify from the browser?

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

Are OOPSpam and ipify free for commercial use?

OOPSpam has unclear commercial terms, and ipify allows commercial use on its free tier. 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.
