pqlq.com is a modern, fast IP and request-inspection service. Hit / in a browser for a compact network mirror, or curl / from a shell for plain-text output. Endpoints under /api/v1 return structured JSON for programmatic use.

Geo, ASN, and hosting-provider data are looked up from local files at request time — no external API calls, no third-party rate limits, no visitor IPs leaked to upstream services. Lookups are sub-millisecond.

The public service is free for casual use. If you are building a product against it, need a guaranteed SLA, want a dedicated rate limit, or are deploying at scale where you want a stable contract — get in touch and we can set you up with a dedicated API key.

Email [email protected] with a short note about your use case and expected volume, and we will reply with options. Self-hosting the open-source code is also a valid path — the repo includes everything needed to run your own instance.
