API Access

Simple REST API. Grab your IP, geo, ASN or full metadata with a single curl.

Privacy First

Zero logs, zero cookies, zero tracking. Your data never touches a database.

Developer-First

Content negotiation built-in: browsers get HTML, curl gets plain text, scripts get JSON.

API Endpoints

Limitations

Behind a proxy or VPN: the displayed IP is your exit node, not your device.
IPv4/IPv6 depends on your network stack and ISP support.
Geolocation accuracy varies; city-level data may be incorrect.

Geolocation is derived from network metadata and may not reflect your physical location. Accuracy varies by ISP and region.

Global Edge Infrastructure

ip.clk.am runs on Cloudflare's global edge network across 300+ cities in 100+ countries. Every request is routed to the nearest point-of-presence, delivering sub-50ms response times for most of the world. There is no single-origin bottleneck, no cold-start latency, and no regional failover to configure. The service is stateless by design — no database queries, no disk I/O — so it scales to any traffic volume without degradation. Uptime follows Cloudflare's SLA for edge Workers.

Why ip.clk.am?

Several alternatives exist — ifconfig.me, ipify.org, icanhazip.com — and they all return an IP. The difference is in the details. ip.clk.am serves the same endpoint with content negotiation: browsers get a full HTML page, curl gets plain text, scripts get JSON or YAML — no endpoint switching needed. It is dual-stack: IPv4 and IPv6 are both detected, and when you connect over IPv6 the page fetches your IPv4 from a secondary probe automatically. The service is free and imposes no rate limits for reasonable programmatic use. There are no API keys, no sign-up, no quotas. Geolocation, ASN lookup, reverse DNS, and HTTP header inspection are all available as discrete endpoints on the same base URL. Everything runs at the edge — no proxying to an origin, no latency tax.

Common Use Cases

DevOps provisioning: retrieve your build agent's egress IP to add it to firewall allowlists or security group rules.
CI pipeline IP allow-listing: use /json in a pipeline step to dynamically whitelist the runner's IP before hitting a staging API.
Geofencing verification: confirm a client's country code server-side before serving region-locked content.
Fraud detection: cross-check the IP a user submits against the IP their browser actually uses.
Home network monitoring: poll ip.clk.am/json on a cron and trigger a webhook when your public IP changes.
VPN / proxy testing: verify that your exit node is the expected IP after connecting to a VPN or proxy.

Part of CLK.AM

ip.clk.am is one tool in the CLK.AM platform — a privacy-first site intelligence suite built for developers and digital teams. CLK.AM also provides cookieless analytics with full data ownership, and a short-link engine optimized for attribution. All products share the same edge infrastructure and the same design principle: no third-party data brokers, no hidden tracking, no lock-in.
