As answered by people managing ipstack and IPData.info.
IPData.info's answer:
Developers and technical teams who need IP geolocation, ASN lookup, or proxy/VPN/fraud detection in their apps — including SaaS builders, e-commerce and payments teams doing risk and localization, security and fraud analysts, and indie hackers who want a capable free tier without signing up for a key.
IPData.info's answer:
IPData.info started from a simple frustration: existing IP geolocation APIs gated basic data behind keys, low free limits, or paywalled security fields — while charging for what open datasets already provide. The goal was "IP intelligence, without the bill": take free, well-maintained datasets (MaxMind GeoLite2, IP2Location LITE, RIR registries, community threat feeds) and serve them as a fast, key-free API with a generous free tier and transparent paid plans for teams that need higher volume.
IPData.info's answer:
IPData.info is built using modern cloud-native technologies, including:

IPData.info's answer:
IPData.info delivers full IP intelligence — geolocation, ASN/network, timezone, currency, and security signals (proxy/VPN/Tor/hosting detection) — for free, with no API key and 50 requests/minute. Its JSON is an ipwhois.io-style enriched superset, and every response is available in JSON, XML, CSV, newline, and PHP formats. Enrichment runs entirely on free/offline datasets (MaxMind GeoLite2, IP2Location LITE, RIR registries, IANA tzdata), so there's no third-party API call per lookup. It also ships a rare extra: a free DNS/EDNS resolver API that detects which DNS resolver a client actually uses and whether it leaks an EDNS Client Subnet.
IPData.info's answer:
Most IP APIs paywall security signals, throttle the free tier hard, or require a key just to start. IPData.info gives you country, city, ASN, timezone, currency, and proxy/VPN/Tor/hosting flags for free, no key, at 50 req/min — then scales with simple, honest pricing (Basic $9, Pro $25, Business $79) and no overage fees. You get five output formats, IPv4 + IPv6, a backwards-compatible enriched JSON schema, and a free DNS-leak/EDNS resolver endpoint that competitors like ip-api charge for. Same data, fewer restrictions, lower cost.
