Free IP Geolocation API for EU Developers: 2026 Buyer’s Guide

5-minute read · 2026 pricing · honest assessment

If you’re building a SaaS, an e-commerce checkout, or a fraud signal, you’ll eventually need to ask “what country is this visitor coming from?” — and the free tier of an IP geolocation API is usually where that journey starts. The problem in 2026 is that “free” hides three very different things:

1. Free with attribution required (a back-link in your footer)
2. Free with HTTPS reserved for paid plans
3. Free with key features (VPN/Tor detection, ASN, organization) gated to paid

This post walks through what to look for in 2026 — and where IP Geo API fits.

1.000 requests/day: who actually needs more?

For most B2C web apps, 1.000 lookups/day is the realistic ceiling for the first 6-12 months. A simple math check:

• 100 unique visitors/day → 100 lookups (one per session)
• Geo-pricing on a checkout? Roughly equal to your conversion funnel top.

If you’re crossing 1.000 lookups/day, you’re past the validation phase and should be looking at a starter plan anyway (about €29/mo at iploc.eu).

What free really means in 2026

The “included threat detection on free” is the single biggest differentiator in 2026 — most competitors moved VPN/Tor flags to a paid Security Module (ipstack, ipgeolocation.io, ipinfo all do this in some form).

The migration cost from a free tier

Free tiers are sticky because the migration cost compounds:

• You build assumptions into your code (field names, response shape)
• You snapshot pricing in a vendor comparison spreadsheet and forget about it
• You don’t bother re-evaluating until rate-limit emails arrive

IP Geo API’s response shape is intentionally close to the de-facto industry shape (ipinfo + ipapi.co), so most migrations look like a one-line endpoint swap:

- curl https://ipinfo.io/8.8.8.8?token=$TOKEN
+ curl https://iploc.eu/api/lookup?ip=8.8.8.8

Field names map 1:1 for country, region, city, lat, lon, org, asn. The is_eu, is_vpn, is_proxy, is_tor flags are additive — your existing code keeps working.

When the free tier is NOT enough

Be honest with yourself:

1. You need >1.000 requests/day → starter plan
2. You need batch lookups (e.g., enrich 100k historical sessions) → business plan
3. You need a contractual DPA + SLA → starter or business
4. You need offline (database file) lookups → not us; look at MaxMind or IP2Location
5. You need 200ms SLA on a single endpoint → us, but verify with a load test

GDPR posture in plain English

EU hosting matters for two reasons:

• Article 44 transfers: if your DPA says “no transfer outside the EU/EEA”, the IP geolocation lookup must terminate inside the EU. A US-hosted API fails this even with a Standard Contractual Clause.
• Data residency clauses in B2B sales: enterprise buyers increasingly require an EU-hosted stack as table stakes.

IP Geo API runs in Frankfurt + Amsterdam (Hetzner), with no data leaving the EU. The DPA is downloadable and signed by the operating BV.

What to do this week

1. Sign up for the free tier (no credit card)
2. Swap one API call in a staging environment
3. Compare the response shape against your current provider for 24 hours
4. Decide based on the diff, not the marketing page

If the free tier holds for a week, you’ve got your answer. If it doesn’t, the paid plans are designed to scale linearly from there.
