Precise IP Geolocation. Proven Daily.

Every HTTP request includes a user-agent string — a snippet of text identifying the browser, operating system, and device making the request. The format varies significantly across clients, and parsing it reliably requires keeping up with a constantly changing landscape of browsers, bots, and device types....

This API returns active IANA time zone information for any time zone identifier — current UTC offset, daylight saving time status and schedule, and current local time. If you pass a UTC reference time, it converts that time to the local time of the specified zone....

This API returns the same time zone information as the Time Zone Info API — IANA time zone identifier, UTC offset, daylight saving time status, and current local time — but resolved automatically from an IPv4 or IPv6 address rather than requiring you to know the time zone identifier upfront....

This API returns detailed information about any country by ISO 3166-1 code — including isoAlpha-2, isoAlpha-3, and m49 numeric codes. The response includes ISO-defined names, official languages, currencies, calling codes, flags, UN region classifications, and World Bank income level....

This API returns country-level information for any IPv4 or IPv6 address — ISO names, official languages, currency, calling code, UN region classification, and World Bank income level — derived from the same patented geolocation technology that powers our full ...

Most IP geolocation providers work backwards from database records — WHOIS registrations, user submissions, or latency probes — all of which have well-documented accuracy limits. BigDataCloud takes a different approach.Our patented technology (US Patent No. 11,792,110 B2) maps the actual routing structure of the internet: every public router interface is identified and categorised, its geographic service area is calculated using verified ground truth data, and any IP address is then located by finding the router responsible for delivering traffic to it. This means our results are grounded in how the network actually works, not how it's registered or how it responds to pings....

This API returns the same geolocation data as the IP Address Geolocation API, with one important addition: a confidence area polygon.Where most geolocation APIs return a single coordinate, this endpoint also returns a set of coordinates forming a closed polygon — the realistic boundary within which the IP address is likely operating. This boundary is derived from our router service area analysis: we calculate the actual geographic coverage of the network infrastructure responsible for that IP, based on verified ground truth data. The result is an honest representation of location uncertainty rather than a false sense of precision....

This API combines everything in the IP Address Geolocation with Confidence Area API with the Hazard Report — a set of risk signals designed to help you make faster, more informed decisions about incoming traffic.Most risk tools only look backwards: is this IP on a blocklist? Has it been flagged before? The Hazard Report adds a forward-looking dimension. It assesses whether an IP belongs to hosting infrastructure rather than a residential network — a strong indicator of automated or non-human traffic — even when there's no prior incident history. That combination of reactive signals and proactive indicators gives you a more complete picture of threat likelihood than blocklist checks alone....

An Autonomous System (AS) is a collection of IP routing prefixes managed by a single administrative entity — typically an ISP, hosting provider, university, or large organisation. Each AS is identified by a globally unique Autonomous System Number (ASN), which governs how it exchanges routing information with neighbouring systems....

This API returns detailed information about the active network a specific IP address belongs to, including the Autonomous Systems (AS) that announce and serve that network — registration details, IP prefix, and neighbouring system relationships.It's useful when you need network-level context rather than geographic location: identifying the ISP or organisation behind an IP, understanding the network topology, or enriching logs and analytics with provider information....

The Hazard Report API provides a consolidated, machine-readable assessment of IP address risk, combining reactive signals (evidence of past malicious behaviour such as blocklist appearances and known anonymiser detections) with proactive indicators (the likelihood that an IP belongs to a hosting or data-centre environment with no real user behind it)....

Captchas are a blunt instrument. They protect against bots, but they also slow down legitimate users — and the frustration is real. One way to reduce that friction is to skip the captcha for visitors whose IP address shows a strong signal of genuine human traffic....
