PyPI vs ReqRes: common questions

Which is more reliable, PyPI or ReqRes?

Both are neck-and-neck — PyPI and ReqRes 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, PyPI or ReqRes?

PyPI has the lower median latency in our checks — PyPI responds in 46 ms versus ReqRes at 256 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 PyPI and ReqRes need an API key?

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

Can I call PyPI and ReqRes from the browser?

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

Are PyPI and ReqRes free for commercial use?

PyPI has unclear commercial terms, and ReqRes 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.
