WorldIP.io
A free API that tells you where an IP address is, who owns it, and whether it looks like a VPN, proxy, or datacenter — usable instantly with no signup, and with paid tiers if you need higher volume or fraud-detection-grade data.

Description
Knowing basic facts about an IP address — its country, its owner, whether it's likely a VPN or a bot farm — comes up constantly in fraud prevention, analytics, and access control, and most services that provide it either require a signup wall or come with confusing pricing tiers. WorldIP.io's core pitch is removing that friction: a keyless API you can start querying immediately, covering the full IPv4 address space (4.3 billion addresses).
WorldIP.io returns geolocation (country, region, city), ASN and CIDR range data, reverse DNS records refreshed in under 24 hours, and VPN/proxy/datacenter detection, backed by live BGP feeds from 23 RIPE RIS route collectors and RPKI validation monitoring — plus some Web3 blockchain node mapping. The free tier allows 1,000 lookups/day with core descriptive data (roughly 10x higher with a free account signup), full API documentation is available with cURL, PHP, Node.js, and Python examples, and paid tiers scale up: Basic at $9/month (25,000 enriched lookups), Pro at $39/month (adding VPN/proxy/trust scores), and Business & Scale from $129/month (live BGP feeds, bulk operations).
💬 Our review
The short version: for basic geolocation and ASN lookups, WorldIP.io's no-signup free tier is a genuinely convenient way to get started immediately, and the pricing ladder scales sensibly if you later need VPN/proxy detection or bulk operations.
The technical backing — live BGP feeds from 23 RIPE RIS collectors and RPKI validation monitoring — is a real differentiator versus IP databases that just ship a static lookup table updated occasionally; that infrastructure suggests genuinely current routing data rather than stale snapshots. The free tier's 1,000 lookups/day (10x with a free signup) is generous enough to prototype a real integration before paying anything. The main thing to verify yourself is detection accuracy on the paid VPN/proxy/trust-score tiers ($39+/month) — that's the hardest part of this category to get right, and it's worth testing against your own known-bad IP samples before committing budget, since no third-party IP intelligence provider has perfect detection rates in this space.
