Quick answer
Free IP API - Free IP API wins for most builders because its free tier is much more usable day to day, while Antideo is better only if you need email or phone validation alongside IP checks.
How the free tiers compare
These two free tiers solve different problems. Antideo is a mixed validation API: IP geolocation and reputation plus email and phone number checks, but the free tier is very tight at 10 requests per hour and is best treated as a tiny sandbox. Free IP API is narrower on data types, focused on IP geolocation and network data, but its free tier is far more practical at 60 requests per minute and includes commercial use, bulk lookups, API keys, and global features on paid plans. If you want to build, test, or ship something with real traffic, Free IP API gives you much more headroom before you pay. If your product needs email or phone validation in the same vendor, Antideo has the broader API surface, but its free quota is the main constraint.

After you outgrow the free tier
Antideo uses a flat monthly ladder that starts at $5/mo for 50 requests/hour and rises to $80/mo for 2000 requests/hour. Free IP API is also mostly flat-priced: €9.90/mo for Unlimited, €99/year for the yearly plan, and custom Enterprise pricing. The big difference is scale. Antideo is cheaper at the first paid step, but Free IP API’s free tier is much more generous, so many small builders can stay free longer. Free IP API’s Enterprise plan is contact sales.
Cost at real usage
| Usage | Antideo | Free IP API |
|---|---|---|
| Light product use, well under free limits | Free | Free |
| Need to exceed free quota but stay at a small paid tier Antideo’s first paid tier is cheaper, but its free cap is much lower. | $5/mo for 50 requests/hour | €9.90/mo for Unlimited |
| Need around 100 requests/hour capacity Free IP API does not publish a lower paid step for this use case. | $10/mo for Pro | €9.90/mo for Unlimited |
| Need around 1000 requests/hour capacity Free IP API’s Unlimited plan already removes minute-based caps. | $50/mo for Growth | €9.90/mo for Unlimited |

When to pick each one
Pick Antideo when…
- You need IP geolocation, email validation, and phone validation from one API vendor.
- You only need a very small sandbox for occasional testing, with 10 requests per hour enough.
- You want to check IP reputation, disposable email, or phone carrier details in the same stack.
- You prefer a simple flat paid ladder if you outgrow the free tier.
Pick Free IP API when…
- You need a free tier that can handle real product usage instead of just testing.
- You want commercial use allowed on the free plan.
- You need bulk IP lookups, API keys, and IPv4/IPv6 support from day one.
- You expect to stay on a free plan for a while before paying.
- You want much higher request headroom before moving to a paid plan.
Bottom line
For the common builder, Free IP API is the better free tier because it gives you far more room to build before you hit a wall. Antideo only becomes the better choice if you specifically need email validation, phone validation, or IP reputation checks in the same service. If your use case is mostly IP lookup and you care about staying free as long as possible, Free IP API wins. If your use case is broader validation, Antideo has more endpoints but a much tighter free allowance.
