LCBO vs NPPES: common questions

Which is more reliable, LCBO or NPPES?

Both are neck-and-neck — LCBO and NPPES each measure 100% uptime over 90 days on our probe schedule. Reliability here is verified from our own scheduled checks; use the 30-day bars above to see which has been steadier lately.

Which is faster, LCBO or NPPES?

LCBO has the lower median latency in our checks — LCBO responds in 207 ms versus NPPES at 910 ms (P50). Tail latency (P95) is in the table above; for most workloads the median is the number that shapes how the API feels.

Do LCBO and NPPES need an API key?

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

Can I call LCBO and NPPES from the browser?

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

Are LCBO and NPPES free for commercial use?

LCBO has unclear commercial terms, and NPPES 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.
