CompanyData.com vs CoinGecko: common questions

Which is more reliable, CompanyData.com or CoinGecko?

Only CoinGecko 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 CompanyData.com and CoinGecko need an API key?

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

Can I call CompanyData.com and CoinGecko from the browser?

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

Are CompanyData.com and CoinGecko free for commercial use?

CompanyData.com has unclear commercial terms, and CoinGecko 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.
