BlockCypher vs Coinlore: common questions

Which is more reliable, BlockCypher or Coinlore?

Only Coinlore 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 BlockCypher and Coinlore need an API key?

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

Can I call BlockCypher and Coinlore from the browser?

Yes — both BlockCypher and Coinlore send CORS headers over HTTPS, so front-end code can fetch either directly with no backend proxy. That makes them easy to swap in a client-side app while you compare responses.

Are BlockCypher and Coinlore free for commercial use?

BlockCypher has unclear commercial terms, and Coinlore 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.
