ipto vs ipapi.is

ipapi.is positions itself as a cheaper, higher-quality alternative to IPinfo, and its free tier is a genuine standout: 1,000 requests/day with the same data quality as paid plans, by their own claim — VPN, datacenter, and abuser detection included, not gated behind a paid tier. The catch is the daily cap itself; past 1,000/day it's a $20/month Basic plan for 20,000/day.

FAQ

That's their own claim — the free tier is stated to return the same data quality as every paid plan. The only thing volume buys you is a higher daily request cap, not new fields.
Requests beyond the daily free cap are throttled or rejected until the next reset, per ipapi.is's published limits. ipto's free tier has no daily request cap to run into.
