World Trading Data vs CoinGecko: common questions

Which is more reliable, World Trading Data 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 World Trading Data and CoinGecko need an API key?

Both ask you to authenticate — World Trading Data uses an API key and CoinGecko uses an API key. Each key is free to obtain; the Auth and Card-required rows above spell out the signup terms.

Can I call World Trading Data and CoinGecko from the browser?

Neither sends browser-friendly CORS headers reliably, so call World Trading Data and CoinGecko from a server or proxy rather than client-side. The CORS and HTTPS rows above show exactly what we detected for each.

Are World Trading Data and CoinGecko free for commercial use?

World Trading Data 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.
